Rare Carat Leads the 2025 Lab‑Grown Diamond Boom

Rare Carat Leads the 2025 Lab‑Grown Diamond Boom

With shoppers tilting toward lab‑grown for sparkle‑per‑dollar and transparency, Rare Carat’s marketplace aggregates a massive selection of lab stones and layers on AI price/quality scores and GIA‑trained gemologist opinions—turning comparison shopping into a science. (Rare Carat)

What’s new in 2025: GIA’s grading shift

GIA will launch an updated evaluation framework for D–Z lab‑grown diamonds on Oct. 1, 2025—moving away from the traditional natural‑diamond 4Cs presentation toward simplified categories (widely reported as “Premium/Standard”). Expect labeling and report language to change, with laser inscriptions and digital verification continuing. This change aims to better reflect the tighter quality range typical of LGD production.
