Clarity

Natural gemstones are not created in laboratories with perfection, but are created by mother earth with immense power thrust within them; therefore they might contain inclusions, which affect the clarity of the gemstone. Lesser the inclusions, rarer the gemstone. Though there is no standard clarity measurement scale for Colored gemstones, Diamonds are graded on a fixed clarity grading scale. Colored stone cannot be graded on a fixed scale because the possibility of inclusions vary from stone to stone, Ex: It is more obvious to find inclusions in emeralds than in blue sapphires. Even the best quality of emerald might have few noticeable inclusions. Therefore the grading scale vary from gemstone to gemstone.

Cut

A polished gemstones beauty lies in its complex relationship with light: how light strikes the surface, how much enters the gemstone, and how, and in what form light returns to your eye. All these attributes depend on the quality of cut which in turn depends on the perfection of the human being shaping and faceting the gemstone. Cut evaluation includes judging the shape, type of cut and quality of cut & polish. Experienced Lapidaries cut a gemstone to bring out the best of it !

Carat Weight

Carat is a weight measurement unit, which is generally used to weigh gemstones. One carat equals 200 milligrams in weight. For gemstones under one carat, each carat is divided into 100 points – similar to pennies in a dollar. 0.75 ct. = 75 points, 1/2 ct. = 50 points.
