Sell Sapphire Jewelry · Nationwide, by Mail
Bizak & Co. buys sapphire jewelry from sellers across the United States — mail it in on a free, fully insured label. Sapphire isn't only blue: our trained gemologist reads color, saturation, origin and treatment, whatever shade you have, and sends you the offer in writing — separate from whatever the metal is worth. An established Miami jewelry house since 1996.
Sapphire isn't only blue. It's the same mineral family as ruby (corundum), and it comes in pink, yellow, violet, green, colorless, and the rare orange-pink "padparadscha" — each priced on its own scale, not against blue sapphire. A vivid cornflower or royal blue remains the most recognized and typically highest-demand color, but a fine pink or padparadscha sapphire of good saturation can be worth more per carat than an average blue stone of the same size. Color evenness and saturation matter more than which color it is.
Heat treatment is extremely common — over 90% of sapphires on the market have been heated to improve or intensify color and clarity, and it's standard, disclosed practice that barely affects price for most stones. The exceptions are the high end: an unheated sapphire with documentation, or a stone from a source known for exceptional unheated material, brings a real premium.
Sapphire is one of the hardest gemstones — a 9 on the Mohs scale, just below diamond. That durability is why it shows up so often in rings that were worn every day for years: engagement rings, eternity bands, and everyday stacking rings. It also means sapphire jewelry tends to survive in better physical condition than emerald pieces of the same age, which affects what's typically being sold — well-worn rings rather than fragile heirlooms kept in a box.
Origin creates some of the widest price spreads in the gem trade. Kashmir sapphire is the rarest and most valuable origin, from a source largely exhausted over a century ago — genuine Kashmir material with lab documentation is a premium event, not a routine appraisal. Burmese (Mogok) sapphire is also highly valued. Ceylon (Sri Lanka) is a major, well-regarded commercial source. Montana sapphire, often small and lighter in tone, is priced differently again, sometimes valued for being domestic and untreated rather than for size.
Blue sapphire engagement rings (a long-standing alternative to diamond), sapphire eternity bands, colored sapphire cocktail rings, and estate pieces with unusual fancy-color stones the owner isn't sure how to value.
15 years of wear, moderate wear on the band, heat-treated blue stone — appraised on color and condition, offer made in person.
Unfamiliar to the owner as a "sapphire" at all since it isn't blue — evaluated on its own color grade rather than compared to blue pricing.
The documentation is checked against the stone before finalizing the offer.

It depends on the buyer. Some price by melt value alone and treat any stone as incidental. Bizak & Co. evaluates the sapphire separately — by color, clarity, carat weight and origin — and shows that value on top of the metal in writing.
Not necessarily. Sapphire comes in many colors, each priced on its own scale rather than against blue. A fine pink or padparadscha sapphire of good saturation can be worth more per carat than an average blue stone of the same size.
Yes. A lab report can support a higher offer when it documents a rare origin or confirms no heat treatment, but it isn't required — our gemologist grades the stone in person either way.
