Natural Type A positioning
Where stated, material is presented as 100% natural with no treatment — aligned to the verified Imperial Green Type A record.
Authenticity and responsible gemstone trading
We recognise the importance of transparency and confidence in the international gemstone business. Independent gemological testing can help establish gemstone identity and detect treatments.
Due diligence
Clarity before commitment
For significant transactions, buyers are encouraged to undertake appropriate inspection, laboratory verification and commercial due diligence. Product availability, specifications, pricing and supporting documentation are communicated on a transaction-specific basis.
We do not invent laboratory affiliations, origins, or certifications beyond information supplied for each catalogue record. Buyers should verify material independently for significant transactions.
Buyer due diligence
We encourage inspection arrangements, photographic review and independent laboratory verification for significant purchases.
Transaction clarity
Weights, dimensions, colour notes and commercial terms are shared privately during enquiry — never as public storefront pricing.
