CIRCA

What CIRCA does

CIRCA is a privately held, New York-headquartered international buyer and reseller of pre-owned fine jewelry, diamonds, and luxury watches, founded in 2000 as SellJewelry and rebranded to CIRCA in 2005. The company purchases items from individual high-net-worth sellers through private in-person appointments at 20 global locations across the United States, Spain, and Hong Kong, as well as through a secure online mail-in service, and pays sellers immediately via bank transfer without fees or commissions. Resale occurs through proprietary online platforms including shop.circajewels.com and the recently launched CIRCA Vault curated-drop boutique, plus the Worthy online auction and tender platform acquired in the October 2023 combination.

The business operates a hybrid buy-side and sell-side model: revenue is generated by the spread between purchase price and resale value across auction, tender, e-commerce, and private sale channels. Acquisition volumes have surpassed $500 million cumulatively since inception, and the company employs 101-250 staff including over 30 credentialed experts (GIA Graduate Gemologists, former Tiffany & Co. and Neiman Marcus professionals, and certified watch specialists from the Fondation de la Haute Horlogerie). Distribution has been built through organic geographic expansion plus two material M&A transactions: the 2019 acquisition of online buyer Mondiamo and the 2023 combination with Worthy.

CIRCA's go-to-market spans enterprise-style field sales (in-person appointments at owned retail locations), direct-to-consumer e-commerce (the online boutique and CIRCA Vault), and B2B trade channels (proprietary auctions and tenders). Leadership is founder-led with Richard Tilles as President, Jeffrey Singer as Co-Founder and SVP, Oren Schneider as CEO, and Shailen Amin as CFO; regional directors oversee buying operations across the US, Spain, and Hong Kong. Industry affiliations include the Gemological Institute of America, American Gem Society, and Jewelry Security Alliance, supporting the company's positioning as the most trusted global buyer of pre-owned luxury.

Direct peers

• The RealReal: NASDAQ-listed online authenticated luxury consignment marketplace for jewelry, watches, and accessories. Most direct comparable on buyer-side digital scale, though CIRCA's instant-cash buyer model differs from consignment.
• Vestiaire Collective: Global peer-to-peer authenticated luxury resale platform backed by Kering, with deep jewelry and watch categories. Comparable as a competing buyer channel for high-end consignors; offers CIRCA a global benchmark on digital resale economics.
• WP Diamonds: Online buyer of pre-owned diamond jewelry and watches offering instant cash offers. Closest pure-play digital direct competitor to CIRCA's mail-in and online selling service.
• 1stDibs: Online marketplace for luxury jewelry, watches, and collectibles connecting dealers and buyers. Comparable as a competing buyer destination for pre-owned fine jewelry with significant jewelry/watch category exposure.
• Watchfinder & Co. Richemont-owned pre-owned luxury watch platform with global buy/sell operations. Comparable as a vertically integrated watch specialist; well-capitalized incumbent in the watch resale sub-vertical CIRCA operates in.

Broad incumbents

• Sotheby's: Global auction house with major jewelry and watch departments, also operating Buy-Now channels and a private sales division. Comparable as a competing buyer of high-end jewelry/watches from collectors and estates, though CIRCA offers instant payment vs. auction timing.
• Christie's: Major international auction house with significant jewelry and watch sales. Comparable as an alternative disposition venue for high-value pre-owned jewelry, particularly estate pieces where auction visibility can outperform instant-purchase offers.
• Bonhams: International auction house with established jewelry and watch departments, including diamond specialists. Competes for the same estate and high-end consigned jewelry CIRCA buys directly.

Emerging players

• Crown & Caliber: US-based online platform specializing in pre-owned luxury watch buying and selling. Comparable as a focused watch-resale competitor with overlapping target sellers (collectors and lifestyle sellers).
• Brilliance: Online diamond and fine jewelry retailer with growing pre-owned and trade-in offerings. Comparable in diamond-jewelry retail expertise and digital buyer reach, though newer to dedicated pre-owned acquisition.
