Condition & character

The candid paragraph, written by the founder.

This stone carries a local CSL screening only. International certification at the laboratory of your choice is arranged before payment — we do not ask anyone to take a local report as the final word. The crystal is clean to the eye; at 10× a small feather sits under one corner of the crown.


Provenance

Bought at Ratnapura and cut there. Origin is our statement, not a laboratory's — the certificate does not determine it.

How the stones are sourced


Notes on this stone

Yellow sapphire from Sri Lanka is often heated to lift the colour. This one is not, which is why it is offered with the certification route described rather than assumed.
