A Gemstone For Every Occasion

multi gemstone pendant

Every gemstone is unique, millions of years old, and has occurred naturally. The different varieties have been loved throughout history because of their beauty, and the story they had to tell. The Ancient Egyptians wore them, as did many of the Kings and Queens of old. The Knights and their Ladies, celebrities, or the famous people of an era. Aquamarine, Emerald and Morganite are varieties of the mineral Beryl. They bring their own beauty and charm to our rings, and other items of jewellery stocked by International Diamond Brokers.

aquamarine diamond ring on pink and green


The beautiful Aquamarine is a pale blue gemstone, with shades of green from traces of iron that have been absorbed into its structure. Aqua is Latin for water, whilst marine means the ocean. True aquamarine is a pale turquoise colour. Similar to the tropical seas whose waters ebb and flow onto pure white sand. Naturally making us think of Paradise. The Aquamarine is the perfect ring to be worn on holiday… and every other day too!

emerald diamond ring


The Emerald is one of our most precious gemstones. Its distinctive green colour comes from chromium, and again, traces of iron. It’s probable that Emeralds were mined in Ancient Egypt, more than three thousand years ago. Whilst people in the Medieval era wore them because they believed that the Emerald had protective powers. During the sixteenth century when the Spanish invaders reached Central and South America, they discovered that the Aztec and Inca Empires were rich in gold and Emeralds. The stones were thought to be sacred, and often carved into jewellery or small goblets. Some of the finest Emeralds we have today come from Columbia. Like the Gachala Emerald, weighing 858 carats. Whilst there is also the traditional belief, that wearing an Emerald will bring love into our lives. So why not treat yourself to an Emerald ring, like the one in the photograph below? An elegant, and sophisticated, item of jewellery.

morganite diamond ring yellow flower


Morganite is a pink or purplish pink gemstone. It was first identified in 1910 and named the following year, in honour of the financier and banker, J.P. (John Pierpont) Morgan. The main sources of Morganite are Brazil, Madagascar, Afghanistan, Pakistan, and the United States of America. It is traditionally believed to attract love, and keep it safe. The perfect reason to wear the faerytale, Morganite ring in the photograph below!

The Best Sapphire Engagement Ring

sapphire diamond cluster ring

The Sapphire Engagement Ring in the photograph above is surrounded by a cluster of Diamonds, set in 18 carat white gold. Like the Diamond and Ruby, the Sapphire is formed of aluminium oxide which occurs naturally in a mineral known as corundum. Whilst its stunning blue colour comes from titanium, and iron. Some of the best of these gemstones are found in Africa, Australia, Sri Lanka, India and Myanmar. The rarest Sapphires have a star pattern within their depths called asterism, made from Rutile wands. The star may be visible if the gemstone is shaped and polished in a cabochon, or rounded dome. Cornflower blue is often used to describe its rich, velvet intensity and depth. Although blue is the most popular, you will find Sapphires in other colours, including yellow and pink.

How to Choose the Best Sapphire

If you have chosen a Sapphire Engagement Ring, or simply because you love this gemstone as much as we do at International Diamond Brokers, how do you find the best one for you? Here are a five things you can look out for which may affect the appearance, and value of your Sapphire:

  • Colour

A classic blue Sapphire should have a pure to violet hue. Any trace of green can diminish the value of the gemstone. The best Sapphires are medium to medium dark in tone, with a vivid intensity and vibrancy.

  • Pleochroism

All Sapphires have this. Showing two colours, when viewed from different angles. Gem cutters usually aim to have the cornflower blue at the top of the stone, and any greenish blue or other shading on the sides. The greater the pleochroism the lower the price.

  •  Colour Zoning

This often occurs in Sapphires, as bands of dark and light blue which are actually growth marks. If the zoning is too obvious the value of the gemstone may be considerably less.

  • Clarity

Sapphires often have inclusions or fractures. Tiny crystals, liquids, or gases trapped inside of them. These don’t affect the value unless they detract from the gemstone’s beauty. The asterism star effect is a valuable inclusion

  • Cut

Low clarity Sapphires with a good colour often have a cabochon cut. Whilst a Sapphire Engagement Ring usually has faceted cuts, to enhance its beauty.

The ring in the photograph below is a stunning example of an amazing Sapphire. It weighs 1.89 carats and is set with an oval faceted, vibrant gemstone. A contrast is achieved by the round brilliant cut diamonds on either side of it. All crafted in 18 carat white gold.

And thine eye is like a star, But blue as the sapphires are…

The Poetical Works of Miss Landon (1839)

A Famous Sapphire Engagement Ring

Sapphires have been popular for many years, with Royalty and celebrities. The Duchess of Cambridge’s ring is an oval 12 carat Ceylon Sapphire, surrounded by diamonds. Prince Charles chose this particular gemstone in the 1980s, to be made into a ring for Lady Diana Spencer, and which was later inherited by their son. Prince William gave it to his future wife, Catherine, in 2010. It is now one of the most famous Engagement rings in the world. Our classic 18 carat yellow and white gold Sapphire Engagement ring is in the photograph below.

Our Professional Service

The deep blue colour of the Sapphire is often seen in Medieval paintings, and stained glass windows. Traditionally regarded as a symbol of Heaven, this blue is said to connect us to our deepest dreams. Whilst wearing a ring set with a Sapphire helps them come true. So the perfect gift, for the one you love. 

Our Sapphires are also set in earrings, pendants, and bracelets. Or our Eternity rings, like the one in the photograph below.

The Perfect Diamond Engagement Ring

A beautiful Diamond Engagement ring is a unique way of saying I love you. The moment when it is given, and the memory this creates are timeless. An eternal gift which is followed by the special day when you also wear a Wedding Ring. While an Eternity Ring can complete the three circles of gold or platinum which have a special meaning for you both. International Diamond Brokers offers a professional and bespoke service, to help you find the perfect rings, because we understand the important part this plays in the celebration of your love.

Tradition, Romance and Love

Men and women have desired beautiful rings from the earliest of times, to wear for their symbolism and status, or as we do now for love. The rings worn long ago by the Ancient Greeks, Egyptians, and Romans signified a man’s intention to marry, and a woman’s connection to him. A diamond has been regarded as a sign of wealth for thousands of years, and in matters of the heart… It is forever. So the perfect gift for the one you love.

“If I know what love is, it is because of you.”

Hermann Hesse (1877 – 1962)

Your Engagement Ring

Being engaged and married are two of the most important occasions in our lives. Your diamond symbolises the love that exists between a husband and wife. Giving an Engagement Ring is a sign of commitment before, and after, your wedding. The beautiful Engagement Rings which International Diamond Brokers have on offer are the perfect choice. If you want a bespoke ring made by our in-house goldsmith, this begins with you selecting a diamond that is just right for you. For more advice on how to find your diamond, please read our earlier post

With this ring I thee wed… Your Wedding Ring

Wedding rings are usually worn on the fourth finger of the left hand, between the middle and little fingers. The Ancient Greeks believed that this finger contained the “vena amoris,” or the vein of love which connected directly to the Bride’s heart. Whilst the Engagement and Wedding Rings made by us take this to the next level, in the skill and care we put into creating them for you. 

Your Eternity Ring… Symbolising forever.

“How do I love thee? Let me count the ways. I love thee to the depth and breadth and height my soul can reach.”

Elizabeth Barrett Browning (1806 – 1861)

An Eternity ring is a beautiful piece of jewellery, representing the love that exists in a relationship. What this symbolises to the Bride and Groom. For this reason two Eternity rings can never be the same because they are truly about you, and the love you share with someone else. A never ending circle of your life, and love. If diamonds are set into your ring they may also symbolise this. They have been used for centuries to show love, fidelity, devotion and friendship. Your Eternity Ring can be created in solid gold or platinum, and set with different gemstones. It is often given to celebrate an anniversary which is an important or special occasion for you. What that will be isn’t universally agreed, so the choice is yours. Although many believe that it should be given on the first wedding anniversary or the birth of a first child. If you would like a matching set of rings, International Diamond Brokers can create all of them for you when you first contact us. We will make them, especially for you. Is it necessary to buy all three rings? Again this is a matter of personal choice, but the number three is traditionally thought to be sacred. Just like marriage or the vows you make in your own special ceremony. It is often used to refer to the Holy Trinity, and Heaven. It is also connected to the past, present, and future. Our bodies, minds, and souls. So intended to be forever, and as we also believe, for you.

The 4 C’s –  Buying the best value Diamond

Using Your Knowledge Of The Four C’s And Without Paying A Premium

If you have are about to purchase a diamond then you need to educate yourself to find out are you getting good deal. – many high street jewellers will encourage you to purchase the diamonds that they have in stock as opposed to sourcing a stone to suit your requirements.

Start by understanding what it is you want from a diamond especially when you look at it; do you want the diamond to sparkle, do you want the diamond to be bright and white, or do you want the largest diamond that your budget can buy you? Unless of course you have an unlimited amount of money to spend on a diamond, you will find that at some point you will have to compromise on one of the four C’s.

The 4 C’s

  • Colour
  • Clarity
  • Cut
  • Carat

The Colour

Or rather – the lack of colour!

When buying a diamond, with the exception of purchasing a fancy diamond, you want your diamond to be as free from colour as possible. The diamond colour grading system begins alphabetically from D and goes right the way through to Z

The colour is an important visual characteristic, the higher the colour grade, the brighter and “whiter” the stone appears. The GIA (Gemological Institute of America) are a diamond certification body and use sub-groupings to further simplify the colour grading system:

  • Colourless are grades D-F
  • Near Colourless are grades G-J
  • Faint  Yellow are grades K-M
  • Very Light Yellow are grades N-R
  • Light Yellow are grades S-Z

What colour grade should you look for when buying a diamond?

Two colour grades apart – left is an E colour diamond, on the right is a G colour diamond.

A diamond which is a colour grade D is deemed as the best and most rare, therefore you pay a premium for a stone of this colour grade. Unless you have a highly trained eye, and have two loose diamonds sitting next to each other on a plain piece of white paper, at least 3 colour grades apart – it is very difficult to see the subtle colour difference. However is can greatly affect the price of a diamond.

Our recommendation would to be to stay in the “near colourless” grades and the “colourless” range, preferably grades G colour and above. Diamonds in the near colourless range will be sensational and bright but without the high price tag. It is not a necessity to have a D coloured diamond, especially when even one colour grade down will look almost identical but may save you a lot of money.

The Clarity

Diamonds are created deep within the earth’s mantle in extreme conditions. The environments in which they develop in are far from controlled and so inclusions and blemishes can form and are present in almost all diamonds. Flawless diamonds are exceptionally rare thus there is a premium should you wish to acquire such a stone. Some jewellers may have a negative view on inclusions and blemishes, but ultimately they are after all, natures hallmark and fingerprint.

The grades for clarity are similar across many certification bodies, with slight variations. The grades are based upon how free from inclusions and blemishes a diamond is using 10X magnification. The clarity is graded with a number of factors in mind such as placement, the size of the inclusion, the number of inclusions, the colour of the inclusion as well as a whole range of other factors.

A diamond viewed through a 10X magnification loupe.

The clarity grades from the IGI (International Gemological Insitute):
  • Flawless – F
  • Internally Flawless – IF
  • Very Very Slightly Included 1 & 2 – VVS1 & VVS2
  • Very Slightly Included 1 & 2 – VS1 & VS2
  • Slightly Included 1 & 2 – SI1 & SI2
  • Imperfect 1, 2 & 3 – I1, I2 & I3

It is advisable to stay above the imperfect range unless it is a specific look that you are going for, as the more heavily included your diamond is, the less valuable it is – so keep this in mind when purchasing your stone.

Slightly Included diamonds are our personal favourite as you can absolutely have a stunning slightly included diamond which is perfectly eye clean and does not impact on your diamonds fire or brilliance. An eye clean stone is a stone which has no visible inclusions, especially in the top table facet, from a distance of circa 6 – 8 inches away from an unaided eye.

An IGI certified diamond.

If you wish you to have a higher clarity diamond, it will cost extra and it is not a necessity, as all you need a diamond to be is eye clean. Otherwise you are paying a premium for a characteristic you cannot physically see without the aid of 10X magnification and a trained eye.

The Cut

Would you like your diamond to sparkle – should have been the title here! A diamond is known for its brilliance, fire and scintillation, which are a direct result of how well it has been cut and how good the proportions, symmetry and polish are. The cut grades are a measure of how well a diamond interacts with light and the light return that it gives.

Round Brilliant Cut Diamond

The cut grades from the IGI are:
  • Excellent
  • Very Good
  • Good
  • Fair
  • Poor

You do not, under any circumstances, wish to purchase a poor or a fair cut diamond. This will simply be a diamond which is either cut too deep or too shallow, which results in light leaking out of the sides and will be a lifeless diamond. It would be like a person without a personality – the sparkle is the epitome of a diamond.

The cut does not refer to the shape of the diamond, however the shape and cutting style plays a role in the overall cut grade. The most popular shape of a diamond is a round diamond, but a diamond can be cut in numerous different shapes including an oval, a marquise or even a heart shape!

The perfect cut arrangement originated in 1919 by Marcel Tolkowsky. He calculated the specifics to achieve a perfect cut diamond, the optimum number or facets, their perfect placements, along with the exact and best proportions to provide the maximum light return and dispersion. This cut is one of the most famous diamond cutting styles, known all over the world and is still used to this day – the round brilliant cut. Other cutting styles include the step cut and mixed cuts.

The Carat

The carat is the measurement of the weight of a diamond. The carat weight is a metric measurement divided into 100 points – the precise weight of a 1 carat diamond is 200 milligrams. To some, a diamonds carat weight can be one of their main priorities. However, if you have a very strict budget this could mean that you are compromising too heavily on another characteristic in order to achieve the biggest diamond for your price range.

You can be clever when it comes to choosing the size of your diamond. For example, if you are interested in a 1 carat diamond and you include in your search a diamond between the ranges of 0.90ct – 0.99ct, it can look very similar in size to a 1 carat diamond and may even spread the same. By lowering your carat weight search, you could find the perfect diamond of a similar size, yet save yourself a lot of money. The spread of a diamond is a measurement in millimetres – an average 1 carat measures around 6.4mm.

Avoid, where possible, benchmark carat weights such as 0.50ct, 0.75 and the definitive 1 carat mark. Diamonds are sold on price per carat basis, and a typical consumer wishes to be able to say that she has a 1 carat diamond solitaire engagement ring, therefore a 1 carat stone costs a premium. Unfortunately there is no steady correlation between the price of a diamond and its carat weight. Discuss with your local jeweller as to what carat you are aiming for and what could look like a similar sized diamond, but without the premium price.

The 5th C?

The Certificate of Course!
Which diamond certificate should you look for?

GIA Diamond Report

The GIA are undoubtedly the most globally recognised diamond graders and have a fantastic reputation; however there are other highly reputable and well known certification bodies such as HRD (Diamond High Council) and the IGI (International Gemmological Institute). The IGI were established in 1975 and have worldwide laboratories including the oldest laboratory in Antwerp, and the HRD were established in 1973 and pride themselves on integrity and developing new ways to screen and examine diamonds.

IGI Diamond Report

Despite how they may seem, diamond certificates are actually not hard written scientific facts but are ultimately an opinion from trained diamond graders. I would advise looking at all reputable diamond certifications with your diamond as this could also save you money when purchasing a loose diamond or an engagement ring. GIA certified diamonds due to a number of reasons, but mostly down to incredible marketing, demand higher prices than the exact same diamond but with an alternative certification.

A standard HRD certificate includes the following information:
  • The date of the diamond report
  • Report number – referring to the laboratories database
  • Shape of the diamond
  • Measurements of the diamond in millimetres
  • The carat weight, the colour grade, the clarity grade and the cut grade – the important four C’s!
  • The finish, polish and symmetry of the diamond
  • The fluorescence of the diamond
  • An inclusion plotting diagram – typically only present if a diamond is over 1 carat
  • HRD cut, colour and clarity grading scales


A diamond exhibiting medium blue fluorescence.

A natural phenomenon is diamond fluorescence which refers to when a diamond emits a glow, typically a blue glow, when under an ultraviolet source such as a black light or strong sunlight. Not all diamonds have fluorescence, only around 25 – 35% of diamonds show a degree of fluorescence. When looking for your perfect diamond we advise to look for diamonds which have none, faint or slight fluorescence. Strong fluorescence can have a negative visual impact on the diamond by making it appear milky or cloudy to the naked eye.

Ask Your Local Jeweller

If you are in the midst of looking for a loose diamond or a diamond engagement ring, you should ask your local jeweller questions on anything you do not understand about the four C’s. Do not be pressured into buying a diamond you do not wish to own, even if you think it is a bargain – it could be a bargain for the wrong reasons.

The Formation Of Gemstones & Organic Gems

True and beautiful natural gemstones owe their development to wonderful natural causes of the world, of which there are many varieties; mineral origin found in rocks, in gem gravels from these rocks, or organic gems from plants and animals – all with no intervention or production from man. For natural mineral gemstones to occur, a combination of temperature, pressure, oxygen, chemical elements and time are all needed for their formation. Different environments and processes produce a variety of gemstones with varying chemical structures and crystal structures which produce such diverse attributes of hardness, colours and optical qualities.

Organic gems have been adored for hundreds of years and are from living things such as plants and animals. Amber is an organic gem of hardened and fossilised tree resin from pine trees, typically from hundreds of years ago. Amber can have inclusions such as insects that were trapped inside the resin as it was forming – such inclusions of insects can increase the amber’s worth. Pearls are another divine and organic gem from the produce of molluscs, either fresh water or salt-water. Starting with a foreign body entering and becoming an irritatant to the mollusc, this causes it to protect itself by producing a layer of nacre to coat the foreign body – this ultimately produces the pearl. Other organic gems include coral, shells, ivory, jet and even tortoise shell.

Mineral gemstones are formed from rocks, of which there are three main types: Igneous, Sedimentary and Metamorphic rocks. These processes form the rock cycle as they are all in a constant state of change, as well as interlinking with sub cycles and cross interactions. The varying types of rocks have their own processes which can change a rock or gemstone’s chemical and physical properties. The earth has several layers that were formed 4.5 billion years ago; the crust, which makes up 1% of the Earth’s volume, is from 3 miles to 25 miles deep, the mantle is said to make up 80% of the earth’s volume, and finally the core which has a solid inner and liquid outer layer – all of these layers and processes produce the stunning gemstones that are found.

  • Igneous rocks – the solidification of magma, the magma rises through the cracks of the earth’s crust and dependent on whether or not the magma reaches the surface, ultimately leads to intrusive or extrusive igneous rocks. Intrusive igneous rocks are formed through the cracks of the earth’s crust or volcanic pipes which are able to cool slowly under the earth’s surface giving, with time and perfect environmental factors allow the magma to form large crystals. If the magma erupts onto the earth’s surface it is then deemed as lava and depending on the rate of cooling, the extrusive rocks can produce medium to very small crystals. Igneous rock gemstones include amethyst, citrine, emeralds, aquamarine, garnets, moonstone, diamond, topaz and zircon.
  • Sedimentary rocks – the consolidation of layered sediments, with igneous rocks on the earths surface and due to factors of erosion and weathering can mean that they are broken down into smaller pieces which are then transported by the wind or water and deposited into pockets. Eventually these pockets are built up into layers through continuous cycles of erosion and deposited on top. Eventually with the layers building over time, pressure begins to build up on the bottom layers causing them to become compact, producing chemical and physical changes, altering its state, and producing new rock formations. An example of a sedimentary rock gemstone would be opal or zircon.
  • Metamorphic rocks – these can be either igneous or sedimentary rocks under tremendous heat and pressure. This happens within the earth’s crust, over time or from direct contact with magma, and can result in the change of the crystal structure. This forms new rocks and minerals, producing new gemstones such as Jade, Turquoise, Ruby, and Sapphire.

The time and effort Mother Nature puts in to create these magnificent gems, what better way to show these gemstones off, than by using them in elegant pieces of fine jewellery…
