What australia diamonds Ltd does
Australian Diamond Supply Ltd. is a private diamond trading company incorporated in New York and founded in 1989 that supplies natural white/colorless diamonds, natural fancy color diamonds, and finished diamond jewelry to trade buyers, collectors, and private clients worldwide. The product range spans loose diamonds segmented by carat weight (0-1 through 5+ carats, including rare stones above 30 carats) and by fancy color (yellow, pink, blue, green, red, cognac, champagne, gray, black, and multi-color), plus matched pairs and a finished-jewelry line of necklaces, earrings, bracelets, and rings set predominantly in 18kt gold.
The company's core technology is a Wix-hosted e-commerce catalog (austdiam.com) with Square payment processing integration for secure transactions; the site functions as a product showcase and lead-generation surface rather than an automated e-commerce engine. Underlying the storefront is a physical sourcing operation that draws on a network of employed expert cutters in five major diamond centers (Australia, Antwerp, New York, Israel, Hong Kong) and additional associates in Australia and Asia, enabling the company to fulfill both stocked and sourced-on-demand orders globally within a few days using credited insured shipping agents.
The business model is a quote-based, one-time-transaction B2B/B2C sales operation. Pricing is not publicly disclosed; customers submit inquiries and receive personalized quotes based on carat weight, color, clarity, cut shape, and certification (predominantly GIA). The company is a proud member of several industry bodies: the New York Diamond Dealers Club (DDC), Rapnet (diamond and jewelry trading), the International Watch and Jewelry Guild (IWJG), the World Federation of Diamond Bourses (WFDB), and holds a lifetime membership in Polygon. The go-to-market is direct via the website and supporting social channels (Facebook, Instagram, LinkedIn, YouTube), with no disclosed channel partnerships, agency of record, or institutional marketing spend. The firm does not disclose headcount, revenue, ownership structure, or management team in the source data.
