What Single Stone does
Single Stone is a Los Angeles-based fine jewelry company founded in 1988 and currently led by husband-and-wife co-owners Ari and Corina Madilian, who launched the signature collection after a decade of sourcing vintage stones and restoring antique jewelry. The company specializes in handcrafted jewelry that uses antique and responsibly-sourced diamonds alongside recycled metals, with all production carried out by skilled artisans in Los Angeles. Its assortment spans bridal, Bold Gold, Cobblestone, Monogram, From the Vault, and Men's Jewelry collections, covering rings, bands, bracelets, earrings, necklaces, and charms at price points ranging from roughly $1,600 for entry bands to over $46,000 for statement pieces.
The business operates a hybrid go-to-market model: a flagship boutique in San Marino, California; direct e-commerce through singlestone.com with virtual and in-store appointment booking; and a curated network of stockist retailers (including Korman Fine Jewelry and Croghan's Jewel Box) supplemented by traveling trunk shows. Revenue is generated primarily through one-time fine jewelry sales and bespoke design services (a 10-12 week consult-to-reveal process for custom engagement rings, wedding bands, and reimagined heirlooms), with ancillary revenue from jewelry repair, restoration, diamond resetting, loose diamond sales, and appraisals. Customer acquisition is driven by visual social channels (Instagram, Facebook, Pinterest), the Single Stone Style blog, email, Google Reviews, and event-based trunk show marketing, while Affirm financing (0%-36% APR) is integrated at checkout to support higher-ticket purchases. The company remains private and founder-owned with no disclosed external investment.

Single Stone competitors and assessment
Company assessmentBroad incumbents
- Tacori: Established US bridal and fine jewelry brand with national wholesale and retail distribution. Comparable end-customer (bridal buyers) but operates at much greater scale and price-point breadth than Single Stone.
- Blue Nile: Online-first fine jewelry and engagement ring retailer, now part of Signet. Comparable DTC jewelry / bridal customer base, but competes across a much wider price band and a fundamentally different (mass-market-configurable) model.
- David Yurman: Large US luxury jewelry house with broad handcrafted collections and own-store retail. Comparable handcraft and premium positioning but materially broader assortment and scale across jewelry categories.
Emerging players
- Mejuri: DTC fine jewelry brand that scaled via venture and influencer-driven marketing with lower average price points. Comparable channel strategy and direct-to-consumer ethos, but price band sits below Single Stone's premium tier.
Direct peers

- Melissa Joy Manning: Sustainable, handcrafted fine jewelry designer based in the Bay Area/Los Angeles. Comparable on craftsmanship ethos, recycled metals, and responsibly-sourced stones, with fine jewelry collections in a similar premium band.
- Mark Broumand: LA-based bridal jeweler focused on antique, old European, and rose-cut diamonds in handcrafted settings. Direct regional peer sharing Los Angeles origins, antique-stone focus, and bespoke bridal positioning.
- Anna Sheffield: NYC-based bespoke bridal and fine jewelry designer known for vintage-inspired settings with rose-cut, old-European, and ethically-sourced stones. Closely overlaps Single Stone's bridal, antique-aesthetic, and made-to-order value proposition.
