Sapphire

Sapphire is gem-quality corundum in every color except red, which is classified as ruby. Blue leads the market, followed by pink, yellow, green, purple, and the rare orange-pink padparadscha.

Most sapphires on the market are heated, a stable practice accepted for centuries. Unheated stones confirmed by a laboratory command a substantial premium. We state the status on every listing.

Documented origin moves sapphire prices by multiples: Kashmir, Burma, and Ceylon stones carry historic premiums over other sources even at matching color grades. We name origin where documented and never invent it.

The rare pink-orange sapphire named after the lotus blossom, historically associated with Ceylon. Fine examples are among the most valuable fancy sapphires.

Every sapphire ships with the Sosna Gems Colored Stone Report, our internal documentation. Independent laboratory certification can be arranged on request, and stones with existing laboratory reports have the laboratory named on the listing.

Yes. Sapphires are the category where we source individually most often, including unheated and origin-documented stones that never reach the public collections. Contact us with your parameters.

Compare them at dusk or under warm indoor light. Commercial stones go ink-dark or gray while fine sapphires keep a living blue, and that behavior predicts long-term satisfaction better than a certificate number.
