Discuss the stone with us
You deal with the trading house that holds the stone, not a reseller. Ask anything about it before you decide.
Treatment and report status stated
Every listing states the treatment we know of and whether a laboratory report is included. Where it is not, one can be arranged.
Photographs and video first
Ask for additional photographs and video, in daylight and under other lighting, before you commit.
Calibrated and matched stones
The single pieces on this page are the online entrance to the house. Behind them, Giri Corporation supplies calibrated and matched stones for jewellery production, mostly handled in person and by direct enquiry.
How an enquiry works
Send the stone reference, or the colour, size and budget you have in mind, on WhatsApp or by email.
We confirm availability and price, and send additional photographs or video. If you want a laboratory report and there is none, we tell you the cost and timing to arrange one.
Before proceeding, we confirm payment, delivery, insurance and the applicable terms in writing.
