What Solid Gold Diamonds does

Solid Gold Diamonds is an Australian luxury diamond jewellery retailer founded in 1983 and headquartered in Perth, Western Australia, with a second showroom in Adelaide, South Australia. The company specializes in diamonds and diamond-set jewellery, with a core assortment spanning engagement rings (Solitaire, Halo, Trilogy, and Accents styles in Round, Oval, Cushion, and Emerald cuts), ladies' and men's wedding bands, certified loose diamonds, fancy coloured diamonds (including rare Argyle pink, blue violet, champagne, yellow, orange, and green), lab-grown diamonds, and ancillary categories (earrings, pendants, bracelets, dress rings). A signature offering is The Argyle Rose™, a convertible ring/pendant built around a 1.36ct radiant-cut 1P-grade Argyle pink diamond.

The business operates a primarily showroom-led, appointment-based go-to-market model supported by an e-commerce website (solidgold.com.au) with a "Design My Ring" online configurator and virtual video consultations. Revenue is generated through one-time sales of finished jewellery and loose diamonds, supplemented by fee-free custom handmade design services and ancillary services (repairs, remodelling, engraving, lifetime warranty, complimentary yearly clean and polish). Pricing is quote-based and not publicly disclosed; affordability is supported by Zip Money installment financing and a 3-month interest-free layby plan. Customers are individual consumers, primarily bride/groom couples and luxury coloured-diamond collectors.

The company is an authorized Argyle Pink Diamonds Select Atelier™ and is certified by the Responsible Jewellery Council, with additional traceable supply relationships with Diavik and CanadaMark diamond producers and GIA grading services. Distribution is domestic Australia only, via the two physical showrooms, virtual appointments, and the e-commerce site with nationwide free shipping. The firm is privately held with no disclosed parent company, institutional investors, or public listing.
