Yes. Zamruth serves collectors, investors, and jewellery houses worldwide. All international shipments are fully insured and dispatched via trusted secure logistics partners, accompanied by original laboratory documentation.
Heating is a traditional treatment that enhances colour and clarity. Unheated (untreated) gemstones are rarer and command a significant premium because they reach their colour entirely through nature. All Zamruth stones are clearly disclosed as heated or unheated in their laboratory report.
Zamruth operates on nearly a decade of direct mine-to-market relationships — not auction intermediaries. We verify every stone independently before offering it, practise complete transparency on origin and treatments, and serve as long-term custodians for our clients' collections, not simply as traders.
