Certifications & Appraisals

Paperwork that means something, from the bodies that back it.

GIA — Gemological Institute of America

American Gem Society

The American Gem Society holds member dealers to a strict code of ethics on pricing, disclosure and consumer protection — a standard we hold ourselves to daily.

Why Certification Matters

A stone is only worth what you can prove about it.

Two diamonds can look nearly identical to the eye and differ enormously in value once cut precision, clarity and color are measured under controlled conditions. Independent certification removes guesswork — and protects you if you ever choose to insure, resell or pass the piece down.

For colored stones, certification also confirms whether a gem is natural, treated, or synthetic — a distinction that can change its value many times over.
