What Adiamor does

Adiamor is a privately held, direct-to-consumer online jewelry manufacturer and retailer founded in 1999 and headquartered in downtown Los Angeles. The company designs, manufactures, and sells engagement rings, wedding bands, loose diamonds (natural and lab-grown), and fine jewelry (earrings, pendants, bracelets) through its own e-commerce site, adiamor.com, with no physical retail storefronts. Its core platform combines a diamond search tool, a design-your-own-ring configurator, and in-house production at a single Los Angeles manufacturing facility, enabling custom and bespoke orders built to consumer specifications.

Adiamor's business model is manufacturer-direct: by cutting out intermediaries, the company captures both wholesale margin and customization flexibility. Revenue is generated through one-time consumer purchases (no subscription component), with average tickets spanning loose diamonds, settings, and finished pieces. Financing is offered through third-party BNPL partners Affirm (0% APR up to 12 months) and PayPal Credit (no interest if paid in 6 months on $99+ purchases), which lowers the upfront cost barrier on high-ticket engagement ring orders. All diamonds are certified by GIA and IGI, and the company backs orders with a lifetime warranty, complimentary appraisal, 90-day complimentary resizing, free worldwide FedEx shipping, and a 30-day return policy.

The company serves individual consumers shopping for engagement, wedding, anniversary, and milestone-occasion jewelry. Marketing is primarily organic: an education blog active since 2010, multi-platform social media presence (Facebook, X, Instagram, Pinterest, YouTube), and earned media in NBC, The Knot, WeddingWire, BuzzFeed, and Telemundo. Distribution is exclusively online from the Los Angeles facility, with no disclosed enterprise/B2B contracts, no outside investors, and no M&A or funding activity in the source data. Leadership is anchored by CEO Sam Sarkisian, with no other named executives disclosed.

Core offering

Adiamor designs, manufactures, and sells diamond engagement rings, wedding bands, loose diamonds (natural and lab-grown), and fine diamond jewelry (earrings, pendants, bracelets) directly to consumers through its own e-commerce site. Each ring is custom-built to order in the company's Los Angeles manufacturing house, and customers can use the "Design Your Own Ring" tool to configure bespoke pieces by pairing a loose diamond with a setting.

Product overview

Adiamor is a direct-to-consumer online jewelry company specializing in engagement rings, loose diamonds, and fine jewelry.

Scale indicators2 records

Expansion highlights5 records

Emerging players

• Clean Origin: DTC lab-grown diamond retailer offering engagement rings and fine jewelry. Competes with Adiamor in lab-grown bridal but does not have comparable natural-diamond or custom-manufacturing scale.
• VRAI: Vertically integrated DTC lab-grown diamond brand. Overlaps with Adiamor's lab-grown diamond offering and DTC engagement-ring design, but with a much narrower (lab-only) positioning.

Direct peers

• Blue Nile: Pioneer in online loose-diamond and engagement-ring sales; acquired by Signet Jewelers, giving it significantly more capital than Adiamor. Direct head-to-head competitor in custom engagement rings and GIA-certified loose diamonds.
• James Allen: DTC engagement-ring and loose-diamond retailer, now part of Signet. Competes directly with Adiamor in custom engagement-ring configurators, 360° diamond imagery, and bridal media partnerships.
• Brilliant Earth: Public, venture-backed DTC jeweler focused on ethical and lab-grown diamonds. Overlaps with Adiamor's ethical-sourcing positioning, GIA/IGI certification, and custom engagement-ring offering.
• Ritani: Online engagement-ring and loose-diamond retailer offering custom ring design with a network of partner jewelers. Directly comparable to Adiamor's design-your-own-ring and loose-diamond search flow.
• With Clarity: Online custom engagement-ring and fine-jewelry brand offering bespoke ring design and home try-on. Closely matches Adiamor's customization-led, online-first bridal positioning.
• Mejuri: DTC fine-jewelry brand selling earrings, necklaces, and bracelets direct to consumers. Comparable online-only, manufacturer-adjacent model, though more skewed toward everyday fine jewelry than bridal.

Broad incumbents

• Tiffany & Co. Global luxury jewelry incumbent owned by LVMH, with flagship retail and bridal lines. Competes with Adiamor in the engagement-ring and fine-jewelry category as a premium benchmark brand, with vastly larger scale and retail footprint.
• Kay Jewelers / Zales (Signet Jewelers): Signet-owned mall-based jewelry chains carrying engagement rings, wedding bands, and fine jewelry. Represents the traditional retail counterpart that Adiamor's manufacturer-direct model is positioned against.
