Treatment Disclosure
Independently verified as a 100% natural, earth-mined gemstone by GST valuer Scott Brown F.G.A.A., NJVA Gold Member No. 033. This verification establishes natural origin. It does not determine whether the stone has been heat treated: heat treatment status is not stated on the supplier's parcel record for this stone and we make no claim either way. Independent laboratory testing is available on request and any result is disclosed in writing before sale.
✓ Assessed in-house by our FGAA gemmologist
100% natural, earth-mined stone. As company policy we do not sell synthetic or man-made gemstones. Where a stone is heated, this refers to traditional heat treatment of a natural stone — it never means the stone is artificial.
