What a Sapphire Actually Costs at Wholesale
Sapphire prices per carat range from roughly $50-300/ct for commercial heated blue material, through $300-3,000/ct for good-to-fine heated stones, up to $5,000/ct and well into the tens of thousands per carat for fine unheated Ceylon sapphires in larger sizes — among the widest price ranges of any gemstone. (Genuine Kashmir material sits far above even that.)
Unlike diamonds, sapphires have no Rapaport-style price list, so wholesale pricing is read from a combination of factors rather than a lookup table. This guide breaks down what drives the number, with approximate wholesale ranges B2B buyers can use to sanity-check a quote. For the grading vocabulary behind these prices, see our blue sapphire grading guide; for the broader framework across all colored stones, our how gemstone pricing works guide.
Sapphire price per carat is defined as the per-carat wholesale value of a gem-quality corundum, determined primarily by color (hue, tone, saturation), origin, treatment status, clarity, and size — with color and treatment typically the two largest factors.
The Five Factors That Set the Price
Approximate Wholesale Price Bands (Blue Sapphire)
The ranges below are approximate wholesale figures for blue sapphire and shift with the market — use them to orient, not to quote.
Fancy-Color Sapphires
Blue is the benchmark, but fancy colors follow their own curves. Yellow sapphires are generally more affordable than fine blue; pink sapphires have climbed with demand as a ruby alternative; and padparadscha — the rare pink-orange variety — commands the highest per-carat premiums among sapphires, often rivaling or exceeding fine blue.
Treatment: The Biggest Swing Factor
Because the large majority of sapphires are heat-treated, an unheated stone of equal appearance is comparatively scarce and priced accordingly — commonly a 2-5x premium, and more at the top. This is why the treatment line on a lab report matters so much; a buyer paying an unheated premium must confirm it — see our guide to buying unheated sapphires and rubies. Our sapphire heat treatment guide explains the treatment hierarchy, and how to read a gemstone lab report shows where treatment is recorded and how the wording varies by lab.
Origin and Size
Origin can multiply price — Kashmir and fine Ceylon at the top — but remember that a country-of-origin determination is a laboratory opinion, not a guarantee, so verify the report wording before paying an origin premium. Size compounds it: gem-quality sapphires get disproportionately rarer as they grow, so per-carat price rises with size at equal quality, most steeply for unheated, top-color goods. For how Ceylon and Thai material differ in practice, see our Ceylon vs Thai sapphire comparison.
Using These Numbers as a Buyer
Price bands are a sanity check, not a substitute for evaluating the actual stone. To buy well:
- Pin down the color precisely — it sets the tier.
- Confirm treatment in writing, and verify any unheated claim with a report.
- Treat origin as an opinion; pay origin premiums only on definitive reports.
- Expect per-carat price to climb with size at the same quality.
- Buy factory-direct where possible to remove broker markups.
