Mine-to-Market Loose Gemstones with Documented Origin

SPB Gems is a direct importer of loose colored gemstones for the jewelry trade. We work mine to market — sourcing stones close to their source and bringing them directly to our New York Diamond District office — so each listing carries a documented origin. The stones below are drawn from our live trade inventory and show the source country or mining region recorded for each stone.

Direct importer

We source loose colored gemstones close to their origin and import them directly, shortening the chain between the mine and the jeweler's bench.

Documented origin

Each stone's listing records its source country or mining region. Trade buyers can see where a stone came from before they buy.

Laboratory grading

Where a stone has been graded, the laboratory and certification are listed on the stone's record — never assumed or implied.
