The rarity, beauty and durability of a diamond has made it the ultimate symbol of love, luxury and status. Ask anyone which gemstone they would most like to own and more often than not, they will say diamond.
When purchasing a diamond, it is important to understand the 5 C’s, this is the industries standard grading system to determine a diamond's quality. So, what are the 5 C’s?
Below, we will be giving you a breakdown of what the 5 C’s are and how you can check the quality of your diamond. For further assistance please ask in store for more details about your purchase.
The cut of a diamond is an important aspect in the quality of a diamond. If a diamond is not cut well, it won’t maximise the amazing sparkle of the stone. Diamonds are cut to a very specific and defined proportion to make the most of the diamonds optical properties. Each cut is called a facet and each facet is designed to allow light to be reflected and refracted from it. One of the most popular cuts on the market is the ‘round brilliant’, this has 57 or 58 facets, each one working just as hard as the next to make the diamond truly sparkle to its best ability.
A diamond's weight is measured in metric carats and takes into consideration the entire diamond, including the depth which can sometimes be hidden inside a setting. Where some diamonds may appear to look the same size, there may still be a difference in the overall carat of both.
Almost all diamonds appear to be colourless but, in reality, only very few diamonds are completely without colour. The majority of diamonds have a hint of yellow that is usually unnoticeable to the naked eye. At T H Baker, we use the industry-standard GIA (Gemological Institute of America) Colour Grading Scale which defines the colour from D through to Z.
It is extremely rare to for diamonds to be completely clear when you look into them. Usually, they contain small marks know as inclusions. These inclusions are formed from the intense conditions which occurred when they were created, so in effect these minor inclusions are birthmarks and show your diamond has lived. Again, for this we use the GIA Grading System to differentiate how many inclusions are visible.
It is now increasingly common for diamonds over 0.25cts to be certified. This certificate is available to give you peace of mind and reassurance when purchasing your diamond. The certificate comprises a brief description of the jewellery item or loose diamond, including an assessment of the 4C’s.
Also, it is important to note that all of our diamonds comply with the Kimberley Process and are ethically sourced.
