At GEMTOPYA the certificate is not a formality — it is the stone's passport. Every gem we hold is graded by an independent laboratory: its species and colour confirmed, its origin identified where possible, and any treatment disclosed in full.
We work with the world's most respected gemmological laboratories, so that what you acquire is verifiable, not merely described.
Independent grading
Each stone is accompanied by a report from a recognised laboratory such as GIA, Gübelin, SSEF, GRS or AGL. The report travels with the stone, always.
Origin, identified
Where the laboratory can determine it, we state the geographic origin of the stone — a meaningful part of both its beauty and its worth.
Treatment, disclosed
Many of our stones are unheated and untreated. Where any treatment exists, it is disclosed plainly. We believe transparency is the foundation of trust.
