About Diamonds

Diamonds were formed about 70 million years ago - due to their hardness, strength and transparency they have become highly sought after and treasured gem stones.

The diamond trade is extremely lucrative and in some countries diamonds had been used to fund wars and conflict. As a result a major milestone occurred when a government run initiative called the Kimberley Process was introduced to stop the flow of conflict diamonds. The Kimberley Process Certification Scheme (KPCS) imposes requirements on participants to certify that shipments of rough diamonds are conflict-free.

The diamonds sold by Jewellery Edition are certified conflict free by each jewellery supplier / manufacturer. Many pieces of 18k and platinum pieces are supplied certificated which is proof that an independent gemological laboratory has confirmed the quality of the diamonds in a particular jewellery piece.

Diamond Certification
All jewellery or stone with a Cerificated Diamond  are independently and individually graded for Colour and Clarity by the Birmingham Assay Office, IGI, IGL or GIA and come with the appropriate grading certificate at no extra cost.

Who provides diamond certification?
Diamond certificates are issued by independent gemological laboratories. There are several grading laboratories, the most prominent being: the International Gemological Institute (IGI) ; the Gemological Institute of America (GIA); the American Gem Society (AGS); the European Gemological Laboratories (EGL) and GemEx Systems. A completed certificate includes an analysis of the diamond’s dimensions, clarity, colour, polish, symmetry, and other characteristics. Round diamonds will also include a cut grade on the report.

GIA Certificate (Gem Institute of America)
The GIA set the standard for diamond grading and gemmological identification, and their grading system serves as the international gem and jewellery industry's benchmark. A dossier is issued for diamonds under 1 carat. Each diamond with a GIA Diamond Report is laser inscribed with the report number. The report includes information about the shape and cutting style, its dimensions, weight to the nearest hundredth of a carat, depth (for round diamonds) and/or width (for fancy shapes), the thickness of girdle and its polish and symmetry. It will also give information about the clarity grade determined under 10x magnification, the colour of the diamond colour and strength of colour viewed under UV light. The document will also include additional diamond characteristics not mentioned in the report.

AGSL Diamond Quality Document (American Gem Society Laboratory) / GCAL (Gem Certification & Assurance Laboratory)
A Quality Document, from the American Gem Society Laboratories, is respected by the jewellery industry as a document of authenticated quality. The AGSL uses a grading system that ranks cut, colour, and clarity on a zero to ten scale, with zero signifying the rarest and most desirable and ten indicating the least desirable. A Certificate of Authenticity, issued by the Gem Certification & Assurance Lab (GCAL), also serves as verification of your diamond's quality. GCAL warrants that each diamond meets the grades and measurements noted in the GIA or AGSL grading report.

Diamond Quality
The quality of a diamond depends on its clarity, carat, colour, cut and shape.

Diamond Clarity
Most diamonds have a few imperfections and are yellow, although this is many are not visible to the naked eye.

Diamonds that are absolutely clear are the most sought-after and therefore the most expensive. Many diamonds have small scratches, trace minerals or other tiny characteristics that can detract from the pure beauty of the diamond.

We would recommend that you look for a diamond, which to the naked eye, appears to have no imperfections.

Diamond Weight
A diamonds’ weight is measured in carat – one carat is 0.2grams. Most diamonds are weighed in hundredths of a carat and it is only a rare few over 1 carat which prove to be extremely valuable. For example, a quarter carat would be 25points or .25 carats.

Diamond Cut
It is the cut of a diamond that can determine its final value. The width and depth can have an effect on how light travels within the diamond, and how it exits in the form of brilliance. If cut too shallow, light can be lost and if cut too high, light can escape lessening the brilliance of the diamond. Whether large or small, cut is critical since releasing a diamond's maximum potential for beauty and brilliance is an art. The polish and symmetry of the diamond cut is also very important. If either are not done well, the light can fracture as it travels through the diamond affecting its brilliance. A well cut diamond is one that maximizes the beauty and brilliance of the stone and is not to be confused with shape.

A+ Very good cut. High quality, white diamonds only very small inclusions. SI clarity or better, H colour or better. Perfect to the eye.
H/SI High Quality Diamonds:
H The colour H is part of the colourless group, and indicates a white diamond with no signs of colour visible from either the top or side.
SI Clarity is an indication of a diamond's purity. It describes the degree to which a diamond is free of imperfections. The internal clarity grade SI is an indication of high quality, the diamond having only tiny inclusions which are not visible to the naked eye.
H/SI indicates specially selected diamonds, hand picked for their whiteness and freedom of inclusions. These are diamonds that you will treasure for their beauty and quality.

A++ Very good cut. Extremely high quality diamonds, diamonds you will consider to be perfect even with a 10x loupe. G VS or better.
G/VS Extremely High Quality Diamonds
G The colour G is part of the colourless group, and indicates a very white diamond with no signs of colour visible from either the top or side.
VS Clarity is an indication of a diamond's purity. It describes the degree to which a diamond is free of imperfections. The internal clarity grade VS is an indication of extremely high quality, the diamond having only tiny inclusions which are not visible to the naked eye or with a x10 loupe other than by a trained expert.
G/VS indicates specially selected diamonds, hand picked for their whiteness and freedom of inclusions. These are diamonds that you will treasure for their beauty and quality.

Ring Settings
It is important to choose the setting that best suits you. And you need to consider not only the actual settings for the diamonds, but also whether you want silver, gold or platinum.

A claw setting is the most commonly used for solitaire rings with claws that rise from the ring shank and hold the diamond tightly. A very expressive way to show off your diamond! Other methods are flush and bezel which enables a more streamlined and contemporary feel to your ring. The diamonds is sunk into the ring itself or a collar which hold the diamond(s) in the ring. A pave setting suits rings with a cluster of diamonds or a channel when the diamonds are set in a channel along two sides of the ring. The type of setting will vary depending on the diamonds within the design and also the type of ring in question.

Hallmarks are special marks on gold, silver and platinum that indicate the purity of the metal. Hallmarks are not needed on gold under 1g, silver under 7.78g and platinum under 0.5g. Other European national hallmarks are accepted in the UK, provided that these represent an equivalent guarantee of quality. Purity hallmarks for 850, 900, 950, and 999 parts per 1000, are made on the piece, the remainder being a mixture of iridium, palladium, ruthenium or other alloys. There are 3 compulsory hallmarks - a maker’s mark, a quality mark, and an assay office mark. These marks establish the origin and purity of the precious metal and ensures it has been accurately and independently tested.

Whilst strong, it is also easy to shape and manipulate. To increase its durability it is mixed with other metals silver, copper, palladium, and zinc. Quality of gold is measured in Karats. 24k (100% gold) and 22k (91.7% gold) are too soft for jewellery. 18k (75% gold), 14k (58.3% gold) are the best karat for fine jewellery - 12k (50% gold) and 9k (37.5k) may also be used for jewellery.

Platinum is 30 times rarer than gold and is the strongest of jewellery metals. They retain their shape due to their durability and develop a soft sheen over time which is a particular aspect of platinum jewellery. If you wish to retain its more reflective shine either buff it with a jewellery cleaner or ask your jeweller. It is also hypoallergenic.

Slightly harder than gold, Sterling Silver (92.5% silver mixed with 7.5% copper) is a silver alloy used in jewellery making.
