Every diamond is a wonder of nature, unique and a miracle of time and chance. Like fingerprints, no two diamonds are the same. With the growth in popularity in diamonds in the early 1950’s, the Gemological Institute of America (GIA) saw a need to standardize the quality of diamonds. By creating the 4Cs of a Diamond -- Carat, Colour, Clarity, Cut buyers and sellers can now communicate with each other in a universal language regarding the quality of diamonds.
The GIA’s 4C’s is now accepted worldwide. In fact, the four C’s of diamond quality is the universal means of measuring the quality of any diamond, anywhere in the world. Particularly with this unique, global standardization, diamonds buyers are now able to know exactly the value of their purchase. [caption id="attachment_1824" align="aligncenter" width="875"]
A Damasci Jeweller will be happy to walk you through the 4 Cs of a Diamond[/caption] 1. Carat Weight Diamonds are sold by the carat (ct.), a unit of weight. Although people think the carat number is determined by the size, some diamonds are smaller, however have "hidden" weight lower in the stone. One carat is equal exactly .2 grams. 2. Colour Colour quality of a diamond is based on the absence of it. A chemincally and structurally "perfect" diamond should be as clear as a pure droplet of water. The GIA's D-Z grading system measures colour by comparing stones under controlled lighting and precise conditions to determine exact colour value. 3. Clarity Diamond clarity is used to describe the presence (or lack) of flaws on the surface or within the diamond. Gems with high clarity grades should have very few flaws. A diamond that is entirely clear is very rare and would be very costly. Most flaws that exist in jewellery grade diamonds are not visible to the regular eye and usually can't be seen without a jeweller's magnifying glass. 4. Cut Quality When we look at the quality of a cut of a diamond, we focus on the proportions of the gem, as rather than the shape. Brilliance and scintillation are achieved by skillfully cutting and polishing the diamond's facets, which allows the maximum amount of light to enter the stone, and reflect and disperse through it, therefore the precision of cuts are paramount.
