About Mackey & O'Brien

Mackeyandobrien.com is a direct-to-consumer jewelry label that focuses on 14k solid-gold chains, signet rings, huggies and pendants set with natural diamonds and untreated colored gemstones. 90 % of SKUs retail between $350 and $2,500, placing the line in the accessible-luxury tier; pieces are sold only through the brand’s own site and its SoHo showroom, no wholesale or marketplaces. The company mills its own chain in Valenza, Italy, then casts, sets and finishes every piece in New York’s Diamond District, allowing them to offer true solid-gold weights at half the gram-price of legacy luxury houses. Their “Build-a-Signet” configurator—live 3-D preview with 12 stone shapes, 6 engravings and 3 gold colors—has become a TikTok favorite and drives 40 % of annual revenue. Core buyers are 24-38-year-old creatives, media professionals and early-career finance women who want heirloom-grade gold without logo-driven mark-ups; sustainability and female ownership (both founders are former Tiffany & Co. bench jewelers) are repeated purchase motivators. The brand’s visual tone is gender-neutral, gallery-minimal and leans on close-up macro shots that highlight millimeter-perfect fit for layered, everyday wear. They compete with heritage Italian chains, celebrity-backed DTC demi-fine lines and mall-based jewelers that plate or hollow their gold. Mackeyandobrien differentiates by guaranteeing minimum 2.5 g gold weight on every piece, publishing real-time gram pricing, and delivering made-to-order solid gold within 10 days—speed and transparency the traditional houses do not match.
