Crystal Certificates

Our GII Certification

Cold Lava Studio is authenticated by the Gemological Institute of India (GII). GII does not simply issue a certificate on request — they randomly select specimens from our stock, test them independently, and issue a certificate of authentication based on those results. We don't choose which pieces get tested. GII does.

Why we don't certify every individual bead

Certifying a single loose crystal is already a rigorous, expensive process. A bracelet or combination piece is made up of many individual beads — and unless every single bead in that piece is independently tested, calling the whole piece "certified" isn't accurate. That's a big part of why genuine, piece-by-piece certification is rare in this industry, and why we don't claim it for every product.

A word of caution

Anyone can print a card that says "certified" and put it in a box. That's not the same as authentication. Real certification means an accredited lab has actually tested the material — not that a label was added to the packaging. Please be cautious of certificates you see attached to crystal products elsewhere without a recognized, accredited lab behind them.

What GII testing actually checks

Accredited gemological testing identifies the mineral itself — not just its appearance — using methods such as refractive index measurement, specific gravity testing, and microscopic examination of internal inclusions, along with other standard gemological techniques. This is how a lab tells a genuine stone apart from glass, dyed material, or a look-alike mineral.

What this means for you

When GII randomly tests our specimens and issues a certificate, it's independent proof that what we say is genuine crystal, actually is. We stand by every random check GII carries out on our stock.
