About Diamond Grading

Carat

0.257 Carat

Often mistaken as a unit of size, a carat actually measures the weight of a gemstone, with 1 carat equaling 0.2 grams. Historically, carob seeds (locust beans) were used as weights for measuring gemstones. It is said that the term 'carat' originates from the Greek word 'Karation,' which means carob seed.

Colour

H: Near Colourless

Many diamonds contain nitrogen and have a slight yellowish tint. The closer a diamond is to pure colorless transparency, the more valuable it becomes. The color grading scale starts with 'D' for colorless and goes down to 'Z' for yellow, divided into 23 alphabetical stages.

Clarity

VS1: Very Slightly Included

Clarity refers to the transparency of a diamond. It is assessed by observing the diamond under a 10x magnification loupe, evaluating the size, number, position, quality, color, and visibility of inclusions, as well as any scratches or wear that occur after cutting. The grades range from 'FL (Flawless),' where no imperfections or defects are observed, to levels where inclusions are visible to the naked eye, categorized into 11 grades.

Cut

3EX H&A: Highest rating in three evaluation criteria, Hearts and Arrows

The cut is the only aspect of a diamond's evaluation that involves human intervention. It is graded on a five-level scale based on ideal proportions, with points deducted for finish quality and craftsmanship.
