About: Our Slabs
The OGS™ Crystal Matrix™
Standard in all Crystal Matrix™ Slabs.
VVS1 is the second highest clarity on the GIA™ Int'l Diamond Grading Scale.
VVS1 denotes minor imperfections visible only under 10x magnification.
Crystal Matrix™ Tamper Seal:
In addition to our proprietary sealing process, OGS™ applies a Crystal Matrix™ tamper seal that will shatter if tampered with.
