Diamond Price Calculator
Use active saleable IZIOS inventory to estimate current lab-grown diamond retail prices by shape, carat, color, clarity, and budget. See median price, common market range, and real matching products.
What this estimate means
This is live retail shopping context, not an appraisal, resale quote, insurance valuation, or natural-diamond valuation. Results exclude archived, unavailable, and actively held inventory.
Lab-grown diamond price by carat
Price does not rise evenly with carat weight. Use calculator range control to compare nearby sizes around popular one-, two-, and three-carat milestones, then open current product matches instead of relying on a fixed historical chart.
Shape price comparisons
Round, oval, cushion, emerald, radiant, pear, princess, and Asscher diamonds can carry different live medians because demand and cutting yield differ. Interactive results compare each shape while retaining nearby carat, color, clarity, and budget filters.
Budget buying guide
Budget coverage shows how much comparable inventory falls under selected maximum. Median and 25th-to-75th percentile range provide more stable context than one unusually low or high listing.
