Assessing diamonds



The 4C’s is the industry standards for assessing a diamond’s quality are Cut, colour, clarity and carat weight. When we are buying these beautiful shiny gems, we carefully consider all these factors and plenty more to ensure your full satisfaction when looking at your diamond for the first time.



Cut and shapeS



A diamond is a true wonder of nature – a rare and beautiful thing – but it is only when a master cutter gets to work that its true brilliance is revealed. Diamond cutting requires great knowledge and accuracy; we source our diamonds from a close network of suppliers who excel at both. Even our melee diamonds – the small sided stones of usually less then 0.05ct – are also selected based on the 4C’s, always trying to get the best quality, the whitest, brightest and cleanest diamonds you can get.


Today’s round brilliant cut diamonds are composed of 57 facets, giving the best shine possible.

The cut of a stone also refers to its shape. The round brilliant cut being the one used the most on the market with its multi-facets and symmetrical design giving an exceptional sparkle which works especially well on engagement rings. Beside the round brilliant there is a huge variety of cuts which you can ask for or will find in our jewellery– brilliant, oval, emerald, pear, marquise, cushion, heart, princess, asscher, and radiant – and we are always ready to hunt for exciting new ones on request.





Finest quality white diamonds



Using colour to describe a diamond is something not always easy to see and understand for an untrained eye, reason why GG is always there to help you choose your diamond colour whether you wish a white diamond or a fancy colour one. Graded on a scale from D to Z, the finest-quality white diamonds are D which are colourless and the further we go down the more yellow and brown tint can be found in the diamond. Arising to the names you might have already heard such as Champagne, Cognac, Canary colours and many others.


Diamonds are exceptional in their colour range. The most common one is the white one as explained above but the rarest ones are the fancy colours such as red, blue, pink, and green, orange, purple up to black. GG is willing to work with fancy coloured diamonds, so you can always ask about fancy colours and it will be a pleasure sourcing the right natural one for you.





Purity of colour



It is this absence of colour that intensifies the flashes of fire visible in the very best diamonds. D and E colour diamonds are frequently referred to as "exceptional whites", F and G's as "rare whites" and only an experienced gemmologist can distinguish between them. Put simply, GG is always looking for purity of colour and high clarity keeping her standards consistently high for you.





Clarity



Each diamond is unique, like a snowflake. Nearly all contain crystals or minerals, formed during their creation in the earth and visible to the trained eye as minuscule inclusions. It is these tiny blemishes, known as inclusions, which affect a diamond's clarity and make it possible to compare two diamonds of exactly the same cut, carat and colour. Ranked on a scale of clarity, the most perfect “flawless” diamonds are renowned for their rarity and value. At the other end of the spectrum are mottled diamonds, the least precious and pretty to look at, mostly used in industries. We are very stringent when it comes to clarity – all GG diamonds are perfect to the human eye.





Carat weight



Carat weight is the factor that everyone's most interested in: how big? But it is not that simple to understand, since the carat is a measure of the weight of any kind of gemstone excepted a few particular ones such as pearls. Keep in mind that the size and the cut of a diamond can make this one seem bigger or smaller than it actually is. Sometimes, higher-carat weight diamonds appear more brilliant because of their greater surface area refracting more light sometimes they can be less brilliant because it has not been cut properly and the light does not reflect properly. Also, it is not necessarily true that a two carat diamond will be twice as expensive as a one Carat stone of identical Cut, Colour and Clarity as the price will vary accordingly to each of the 4C’s. However, larger diamonds do tend to be more difficult to find in nature and therefore much more valuable.
