Six disciplines, one house. Whether you are placing a single significant stone or managing a multi-generation collection, our services are structured around your goal — not ours.
Direct trade in certified loose coloured gemstones and polished diamonds. We supply jewellers, auction houses, and private buyers worldwide.
Every stone we trade carries independent laboratory certification and documented provenance. Pricing is transparent and referenced against live auction and dealer comparables. No hidden markups, no conflict trades.
Three decades of trade relationships in Mogok, Muzo, Ratnapura, Kashmir, and the diamond cutting centres of Antwerp and Surat.
Tell us your brief — size, hue, origin, certification, budget — and we will present three to seven candidates within four to six weeks. For rarer material, longer. We do not offer what we cannot authenticate.
Independent in-house valuation signed by our qualified gemmologists. Reports accepted by major insurers, auction houses, and estate attorneys.
Valuations include full gemmological grading, high-resolution imaging, origin assessment where determinable, treatment disclosure, and fair-market pricing referenced to current comparables. Available for insurance, estate, resale, or acquisition purposes.
We manage submission to the leading independent laboratories worldwide — GIA, Gübelin, SSEF, AGL, GRS, and others.
You choose the lab; we handle the logistics, bonded transit, submission, follow-up, and insured return. For significant stones we recommend dual certification. Turnaround typically two to six weeks depending on laboratory and report tier.
Confidential advisory for collectors, family offices, and institutional investors building long-term positions in coloured gemstones.
Services include portfolio structuring, acquisition strategy, auction representation, estate dispersion planning, and succession advisory. Retainer-based; references available on request. All engagements under NDA.
Fully insured bonded transit worldwide via Brink's, Malca-Amit, and Ferrari. Real-time chain-of-custody from vault to buyer.
Transit insurance covers full declared value. All shipments are tracked and signed on receipt. We handle customs, duties, and compliance documentation. White-glove delivery available in major financial centres on request.
