What adamas does

Adamas Diamonds is an Australian private company, founded in 1983 and headquartered in Perth, Western Australia, that supplies polished diamonds and manufactures and designs diamond jewellery for a global customer base. The core product is loose polished diamonds — both white and fancy coloured — sourced from world-class suppliers and certified through affiliations with GIA, Argyle Pink Diamonds, Rio Tinto, CanadaMark, and the Responsible Diamond Guide, with FCRF membership for coloured diamond pricing research. Each diamond is listed as a unique, real-time-verified SKU on the company's own e-commerce platform at adamasdiamonds.com.au, priced individually on the basis of the 4 Cs and subject to market, currency, and inflation movements.

The company has built a manufactured jewellery line on top of its diamond inventory covering engagement rings, dress rings, signet rings, wedding and eternity rings, earrings, pendants, and bracelets and bangles, supplemented by custom design services and an education portal covering diamond knowledge, the 4 Cs, fancy coloured diamonds, and pricing. Distribution runs through three channels: the consumer-facing e-commerce storefront, a direct sales team reachable at [email protected] for B2B and bespoke orders, and a network of global employee benefit partner schemes whose members access the platform using corporate email credentials. Fully insured courier delivery with signature confirmation is offered worldwide, and payment is accepted via major credit and debit cards plus EFT and PayPal, processed through Commonwealth Bank of Australia.

Commercially, Adamas operates a unit-pricing, one-time-transaction model on individually priced unique items, with no subscription, SaaS, or licensing layer. Pricing is not publicly disclosed in aggregate because each stone is unique; quotes are issued on request and confirmed contractually by email. The primary customer segment is corporate employees enrolled in partner benefit schemes worldwide, with jewellery manufacturers and individual consumers as secondary segments. The company is privately held with no disclosed parent, subsidiaries, funding rounds, management team bios, or financial results, and is presented as actively operating with global reach.
