RINOVA Diamond Guide
Diamond Clarity
Clarity describes the tiny marks formed as a diamond crystal grows — inclusions inside, blemishes outside. Most are invisible without magnification.
The Clarity Scale
From Flawless (FL) to Included (I). Tap any grade to see what it means.
FL/IFVVSVSSII
-
FL / IF — flawless to internally flawless under 10x magnification. Beautiful, and priced accordingly.
-
VVS1–VVS2 — very very slight inclusions, difficult to find even under magnification. This is the grade we set.
-
VS1–VS2 — very slight inclusions, invisible to the eye but visible under 10x.
-
SI1–SI2 — small inclusions, sometimes visible to a careful eye, particularly in step cuts.
-
I1–I3 — inclusions visible to the naked eye, sometimes affecting durability.
One Grade, No Guesswork
Plenty of sellers will tell you SI is fine because most SI stones are eye-clean. Often true — but it means inspecting each stone and trusting whoever inspected it. We avoid the question entirely by setting VVS on everything. You are not buying a judgement call, you are buying a grade printed on an independent report.
Where Clarity Shows Most
-
Where the inclusion sits — one under the table (the flat top) is far more visible than one near the girdle, where a prong may cover it entirely.
-
Step cuts are less forgiving — emerald and Asscher cuts have open, mirror-like facets that show everything. This is where a high clarity grade earns its price.
-
Brilliant cuts hide more — round, oval, pear and cushion cuts break up light and disguise small inclusions well.

Read the report — every IGI report maps the inclusions on a diagram. Send us any report number and we will walk you through it.
