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.
Example lab diamond estimate
Round, 0.90–1.15 carats, F–H color, VS1/VS2/SI1 clarity, maximum $2,500. This is the default example, not a quote for custom URL filters.
Price statistics compare this shape, carat range and grades before the budget ceiling. The match count and browse link apply the $2,500 maximum; the typical price and common range may exceed it.

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.
Learn before choosing
Read lab diamond price guide, understand the 4Cs, compare diamond shapes, and review certification labs.
Calculator questions
What does this calculator estimate?
It estimates current retail shopping prices for active lab-grown diamonds. It is not an appraisal, resale quote, insurance valuation, or natural-diamond valuation.
Why use median and a common range?
Median resists unusually high or low listings. The 25th-to-75th percentile range shows where the middle half of comparable live inventory sits.
Does the lowest price mean best value?
No. Review product media, measurements, cut details, certificate lab, return terms, and current availability before choosing a shortlist.
How current is the catalog data?
Results use active, saleable IZIOS inventory and exclude archived, unavailable, and actively held diamonds. Product pages remain final availability source.
