Understanding Diamond Clarity: From Flawless to Eye-Clean
Deciphering inclusions, internal crystal structures, and laboratory grading nuances
“Learn how diamond inclusions form over billions of years in the earth's mantle and why microscopic characteristics serve as nature's indelible fingerprint.”
Every natural diamond is a geological marvel, crystallizing under intense pressure and extreme heat over 100 miles beneath the continental crust. During this primordial formation, tiny traces of non-crystallized carbon, mineral crystals, or structural graining are trapped within the gemstone.
Laboratories classify clarity into six primary categories across eleven grades: Flawless (FL), Internally Flawless (IF), Very Very Slightly Included (VVS1/VVS2), Very Slightly Included (VS1/VS2), Slightly Included (SI1/SI2), and Included (I1-I3).
For discerning collectors seeking maximum optical value, the VVS and VS spectrum represents the sweet spot of elegance: stones that are microscopically pure to 10x magnification while offering superlative light transmittance.
Our cutting facility in Surat evaluates the position of every inclusion prior to faceting. By strategically orienting facets, our master cutters hide natural graining beneath prong areas or bezel facets, maximizing the unblemished surface of the stone.
