Be it natural or lab grown, diamonds are assessed on its cut, colour, clarity and carat. Universally known as the 4 C’s of diamonds, this grading applies only to diamonds, not simulants. Every Star Carat Shop diamond comes with an IGI certificate.
Cut is the most important grading aspect of the 4C’s. It determines how effective the light that enters the stone is refracted within and then reflected back through the top of the diamond. The overall proportions, symmetry and polishing affects the diamond’s fire, brilliance and scintillation. A well-cut diamond is able to reflect maximum light to the eye, allowing it to sparkle brighter than a poor cut diamond. Only lab grown diamonds of cut grades “Very Good” and above are offered at Star Carat Shop.
Colour refers to the natural hint inherent in diamonds. Graded on an alphabetical scale starting from D (colourless) to Z (light yellow). The closer the diamond is to colourless, the rarer it is. All Star Carat Shop lab grown diamonds possess colour grades between D and H.
Clarity assesses the small imperfections and flaws found on the diamond’s surface and internally, referred to as inclusions or blemishes, typically caused by tremendous heat and pressure. Ranging from FL (flawless) to I3 (included), diamonds graded SI2 and above are not visible to the naked eye. Diamonds that graded below SI2 usually possess imperfections that’s visible to the unaided eye. Star Carat Shop lab grown diamonds are graded SI2 and above in clarity.
Colour denotes the weight of a diamond. 1 Carat is equivalent to 0.2 grams in weight. The value of a diamond (with all other C’s equal) increases significantly as it enters a higher carat weight group. At Star Carat Shop, all jewellery are one carat and above, the savings you get to enjoy as the carat weight increases are significantly greater than that of the natural diamond of the same carat weight.
