    2020 Diamond Price Chart You Should Not Ignore

    How much is a 0.5 carat diamond? A good quality 0.5 carat diamond (H, VS2) is around $3,000 per carat. This means the diamond itself would be priced at $1,500 (0.5 * $3,000). How much is a quarter of a carat diamond worth? A similar quality 0.25 carat diamond is around $2,000 per carat. So the diamond itself would cost $500 ($2,000 * 0.25).
