Carat weight is a measure of a diamond’s weight, and a reflection of its size. One carat is equal to one fifth of a gram (0.2 gram) or 200 mg. One carat is equal to 100 points or 100 cents. Carat weight is related to a diamond’s value because (all else being equal) larger diamonds are rarer than smaller ones.
A quality cut grade allows a diamond to express its natural sparkle and scintillation. Sub-Grades in Cut as a Parameter.
Poor Cut | Fair Cut | Good Cut | Very Good Cut | Excellent Cut
This grade refers to the ‘whiteness’ of a diamond, or its lack of colour. The colour of a diamond is one of the vital factors influencing the price of diamond. In diamonds, the best colour is no colour at all. Colourless diamonds are extremely rare, hence making them the most sought after. Contrary to common belief, all diamonds are not truly colourless. They come in many different colours – commonly faint yellow or brown.
Diamonds are graded for clarity based on internal and external imperfections present.
From Flawless to Included we have divided our Grading System to 6 different grades combining SI1,2&3 and combining I1, I2 & I3. from per GIA’s 11 Grades or AGS’s 0-10 scales.
