Company profile
researched Sep 2026YourDiamonds.com is a Sydney-based diamond technology company positioning itself as a "Global Diamond Hub" serving both diamond industry trade members and private jewellery customers. For trade members it offers a suite of pricing tools and services, including six diamond pricing applications offered free for five years; for private customers it provides instant insurance valuations, written valuations of diamonds, complimentary pre-tender estimates, and participation in its pink diamond tenders. The company's stated themes are democratization, decentralization, digitalization and financial technology, with decentralized finance, "re-cycled economics" and auctions listed as forthcoming offerings.
A secondary strand of the business is the secondary market for Australian fancy-coloured diamonds. The company operates public tenders for second-hand pink and blue diamonds originally mined at Rio Tinto's Argyle mine in Western Australia, which ceased operations in November 2020. Its first tender included the sale of the Fitzpatrick Pink for $2.2 million, reported as a world auction/public tender record for an Argyle-sourced stone. Its third tender, announced in 2022, comprised 60 lots consigned by 22 individuals and self-managed superannuation funds with an aggregate value of AUD$6-8 million, and toured Sydney, Brisbane and Perth before being exhibited internationally in Singapore.
A third-party business-data profile describes the company as enabling the diamond industry to address legacy problems through digital technologies and Web3, monetizing SaaS applications via trading platforms and a decentralized lending system based on DeFi collateralized loans (DCL) appraised using its automated valuation engines, with the diamond sector framed as an initial vertical.
Founding story
Founder Tim Goodman established the largest fine art and jewellery auction enterprise in the Southern Hemisphere, with revenues of $70 million, and was the founding Executive Chairman of Sotheby's Australia Pty Ltd and founder of Bonhams & Goodman. In 1998 he was reported to be the first auctioneer in the world to sell a lot to an online bidder at a traditional fine art auction. He founded YourDiamonds.com and is described on the company's site as its Founder and largest (elsewhere on the same page, second largest) shareholder.
Business model
The company operates a business-to-business and business-to-consumer platform combining subscription-style access to diamond pricing and valuation software with transaction-based activities. Trade members register for access to a suite of tools and services, while private customers pay for services such as written insurance valuations and participate in tenders of fancy-coloured diamonds. A third-party company profile describes the intended monetization as commercializing SaaS applications through trading platforms and a decentralized money-lending system built on DeFi collateralized loans appraised by the company's automated valuation engines.
Revenue is described as coming from monetizing SaaS applications through trading platforms and a planned DeFi collateralized lending system, alongside valuation services for private customers and tender/auction activity in fancy-coloured diamonds.
Traction
The company reported selling the Fitzpatrick Pink for $2.2 million at its first tender, described as a world auction/public tender record for an Argyle-sourced stone. Its third tender attracted 60 lots from 22 individuals and self-managed super funds with an aggregate value of AUD$6-8 million, including a matching pair of Australian pink diamonds over a carat each estimated at $800,000-$1 million. Employee estimates from third-party directories range from 11-50 to 101-200.
Latest developments
In September 2022 the company took its third public tender of Australian fancy-coloured diamonds overseas for the first time, exhibiting at the Jewellery & Gem World Singapore 2022 Fair after a domestic tour, with the tender closing on 3 October. A company profile states the founder and CEO was based in Sydney with a plan to relocate to New York in 2023.
▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies
Market position
The company presents itself as a startup creating the first secondary market platform for trading second-hand Argyle-sourced pink and blue diamonds, a market it describes as involving many hundreds of millions of dollars of stones held by private investors and the diamond trade. Its Head of Operations, a former Argyle mine executive, noted that the mine had produced 90% of the world's pink diamonds before closing and that prices for these stones continue to rise on constrained supply and increased demand.
The company positions itself around objective, transparent and up-to-date diamond market data delivered across mobile, tablet and desktop, allowing private buyers to assess what they should pay for a diamond and to obtain written valuations. It also claims to have created the first secondary market platform for the trading of second-hand pink and blue diamonds originally discovered at the Argyle mine, combining auction and tender expertise from its founder's background with automated SaaS valuation engines intended to underpin collateralized lending.
Technology
The platform is built around diamond pricing applications and automated SaaS valuation engines delivered across smartphone, tablet and desktop, with planned decentralized finance functionality including DeFi collateralized loans. The company states it has assembled a team of digital technology and Web 3.0 developers, blockchain lawyers, IP lawyers, digital marketing specialists, diamond industry veterans, investment bankers and statisticians. Its CTO, Sven Meyer, has a computer science research background and has developed and deployed smart contracts for various platforms; its blockchain counsel, Dr Adrian McCullagh, participates in ISO Technical Committee 307 on blockchain standards. A technology profile lists WordPress, PHP, Elementor, Apache HTTP Server, jQuery, Swiper, WP Rocket, reCAPTCHA, Microsoft 365 and Google Ads among the site's technologies.
Go-to-market
The company markets to two distinct audiences through its website: diamond industry trade members, who register free as "Founding Members" to access tools and services, and private diamond jewellery customers, who are directed to instant insurance valuations, pre-tender estimates and the pink diamond tender. It uses an email marketing list offering industry news, offers and early access to new tools, and gains visibility through physical tender roadshows in Australian cities and exhibition at international jewellery trade fairs, alongside trade press coverage.
Two primary segments: diamond industry trade members, including diamond merchants and jewellery retailers, and private diamond jewellery consumers seeking pricing guidance, insurance valuations or participation in tenders. Tender consignors have included individual owners and self-managed superannuation funds holding Argyle-sourced coloured diamonds.
Geography
Headquartered in Sydney, New South Wales, Australia, with an address at Level 7, 167 Macquarie Street. Team members are based in Sydney, Brisbane, Byron Bay, Melbourne, New York, Amsterdam and Manama, Bahrain. Tenders have to date operated within Australia, touring Sydney, Brisbane and Perth, with the 2022 tender exhibited internationally at a jewellery fair in Singapore. A jobs-board listing also associates the company with Hong Kong.
History
The company was founded in 2020 in Sydney by auction industry veteran Tim Goodman. It launched public tenders for Australian fancy-coloured diamonds sourced originally from the Argyle mine, which ceased production in November 2020; the Fitzpatrick Pink sold at the first tender in 2021 for $2.2 million. By September 2022 it was running its third tender, its first exhibited outside Australia, at the Jewellery & Gem World Singapore fair. A 2022 company website noted six diamond pricing apps available free for five years, with decentralized finance, recycled economics and auctions described as forthcoming. A company profile indicates the CEO planned to relocate from Sydney to New York in 2023.
Risks & controversies
The founder publicly described taking the entire third tender overseas for the first time as a gamble and expressed anxiety about the international launch. Company representatives stated they do not give investment advice regarding pink diamonds. Third-party directory data about the company is inconsistent, including conflicting founding years (2020 versus 2021) and employee ranges (11-50 versus 101-200).
