About
Diamonds last forever, and so should your slabs.
Introducing the toughest slab on the market.
Verify your slabs.
As of March 2026, we implemented a new label design that also includes an extra layer of verification with your slabs. If you have an updated label you can now search the certification number on your slab to verify it in our database.
Over 50,000+ cards graded & slabbed!
