Loose stones only. Every figure on this page is for a loose lab grown diamond as listed, before any ring setting. No blended ring-total pricing appears on this page; setting costs vary by retailer and are never merged into these comparisons.
How current are these prices?
Every price on this page was captured from public retailer listings on September 17, 2026 (September 2026 collection cycle) and is accurate as of that date only. Retailers reprice and delist stones continuously, so any listing shown here may have sold, been delisted, or changed price since capture.
