Lab-grown diamonds cost less because supply is not limited by mining.
A lab-grown diamond is the same material as a natural diamond: crystalline carbon, with hardness and sparkle that match. The price is lower at the same carat, color, and clarity. That gap is widest at 2 carats and above.
Prices still move with cut and with the round-number carat weights. A poorly cut lab-grown round is not a deal if it looks dark. Read the cut grade and watch the video.
Budget pages (under $1,000, under $2,000, under $3,000) and the carat pages are the live price lists. They only include lab-grown stones.
