The Sustainability of Lab Grown Diamonds: Why They Matter

In short: Lab-grown diamonds use roughly 60-70% less energy per carat than mined stones, generate no mine tailings or displaced earth, and many UK and partner labs now run on renewable energy. They share identical chemistry (pure carbon, Mohs 10) and certification (GIA, IGI) with mined diamonds — at 60-80% lower cost. A 1.00ct D/VS1 round lab-grown sits at £1,400-£1,800 in UK 2025, versus £6,500+ mined.
