What Aether Diamonds does
Aether Diamonds is a New York-based, B Corp-certified sustainable fine jewelry company founded in 2018 by Ryan Shearman, Daniel Wojno, Robert Hagemann, and CTO Anthony Ippolito. The company produces gem-quality diamonds using a proprietary four-step process: thermochemical capture of atmospheric CO2, conversion to Atmospheric Methane via green hydrogen, Chemical Vapor Deposition (CVD) diamond growth, and final polishing. The company holds five U.S. patents protecting this process and the resulting diamond composition, and claims that each carat sold removes 20 metric tonnes of CO2 from the atmosphere. All production is powered by 100% renewable energy through a ClearLoop solar farm partnership, and every diamond ships with an International Gemological Institute grading report.
The company sells finished jewelry—engagement rings ($1,705–$7,070), wedding bands ($700–$3,700), necklaces, earrings, bracelets, men's jewelry, and pieces up to $45,000—primarily through direct-to-consumer e-commerce on a Shopify storefront and a strategic channel partnership with Grown Brilliance, which hosts the Aether Collection and handles custom design via its Truly Custom team. Pricing is unit-based with no recurring component; Affirm-powered installment financing supports higher-ticket purchases. Wholesale inquiries are open. Ancillary revenue includes a $4,000 Wedding Offset Package (carbon-neutral ceremony signage, impact assessment, and 62-tonne offset certificate), digital gift cards, and bespoke custom design services.
The customer base is fragmented individual consumers—primarily sustainability-conscious Millennials and Gen Z buyers motivated by ethical sourcing, conflict-free provenance, and wedding/engagement occasions—supplemented by a small wholesale inquiry pipeline. The company is private, venture-backed following an $18.3M Series A led by Helena and TRIREC in March 2022, with no parent company and 11–50 employees headquartered at 445 Park Avenue, NYC.

Aether Diamonds competitors and assessment
Company assessmentDirect peers
- Clean Origin: DTC lab-grown diamond jewelry retailer competing directly with Aether on ethical sourcing and value messaging across engagement and fine jewelry lines.
- Grown Brilliance: Lab-grown diamond jewelry retailer and custom design partner that is both a distribution channel for Aether (Truly Custom collaboration) and a competitor across engagement rings and bridal jewelry.
- Diamond Foundry: Vertically integrated lab-grown diamond producer with a strong ESG narrative (claim of 'zero emissions' in production). Closest head-to-head competitor to Aether in carbon-conscious, premium lab-grown diamonds for jewelry.
- Brilliant Earth: Public DTC jewelry company focused on ethically sourced jewelry, with both mined and lab-grown diamond offerings. Direct competitor in the sustainable bridal and engagement-ring category.
- MiaDonna: Lab-grown and ethically mined diamond jewelry brand with strong climate-positive and reforestation positioning. Comparable to Aether in combining premium jewelry with sustainability credentials.
- VRAI: Lab-grown diamond jewelry brand (subsidiary of Diamond Foundry) emphasizing sustainability and vertically integrated production. Competes head-on with Aether in lab-grown bridal and fine jewelry.
Broad incumbents
- Blue Nile: Large online jewelry retailer (now Signet-owned) carrying both mined and lab-grown diamonds. Comparable in DTC bridal buying experience and has scale, assortment, and financing that could absorb the sustainability-segment growth.
- Lightbox (De Beers): De Beers' lab-grown diamond jewelry brand; a well-capitalized incumbent leveraging parent-group scale and a vertically integrated supply chain. Threatens Aether's pricing power in mid-tier lab-grown jewelry.
- Pandora: Global jewelry giant that has committed to using only lab-grown diamonds across branded jewelry, bringing massive scale and distribution to the sustainable-jewelry positioning Aether competes in.
Emerging players
- Loupe Trove / Scienced Jewelry: Smaller, design-forward DTC fine-jewelry brands emphasizing ethical sourcing and direct supply relationships that collectively crowd the same values-driven consumer that Aether targets.
