MINERALS & GEMSTONES

One place for gemstone and mineral enquiries.

Different materials require different checks. A useful enquiry identifies the exact product form, origin, quantity or carat weight, available quality records and intended destination. Product identity, lawful origin and documentation should be independently verified.

Loose cut diamonds

Evidence matters

Photographs can help describe a material but are not proof of identity, grade, origin or ownership. Independent analysis, gemmological assessment, provenance and legal documentation may be required.

Project enquiries

For a mining or resource project rather than a physical product, provide the location, ownership and licence status, development stage, technical records and the specific partnership being considered.
