Larkandberry

Lark & Berry sells fine and demi-fine jewellery made exclusively with cultured (lab-grown) diamonds and gemstones. Core lines include solitaire and halo engagement rings, diamond-studded hoops, huggies, tennis bracelets, and 14-18 kt gold chains, with pieces from £150 to £8,000. The brand operates its own e-commerce site and two London showrooms (Marylebone and Covent Garden); select collections are also stocked in Selfridges. Every stone is lab-grown, letting the brand claim “zero-mined” diamonds and market 100 % ethical origin. Designs mix classic settings with fashion-forward silhouettes—oversized bezel studs, elongated pear drops, and interchangeable charm necklaces—that have been featured in Vogue and worn by celebrities such as Miley Cyrus and Jodie Turner-Smith. Lark & Berry was among the first UK jewellers to offer lifetime stone upgrades on lab-grown diamonds, reinforcing perceived long-term value. Typical buyers are 25-45-year-old professionals who want traditional luxury aesthetics without mined-diamond baggage. They value sustainability, transparency, and price efficiency—often purchasing engagement rings that are 30-40 % larger for the budget than mined equivalents. The brand’s messaging of “luxury, no compromise” resonates with eco-minded millennials and Gen-Z consumers building capsule jewellery wardrobes. Competitors fall into two camps: heritage houses still using mined stones and lower-price online startups using similar lab gems. Lark & Berry differentiates by positioning at the premium end of lab-grown—hand-setting stones in solid gold, offering high-clarity DEF/VVS grades, and providing in-house repairs, resizing, and lifetime warranties—while still undercutting conventional luxury pricing by half.
