Cobalt Spinel

Cobalt Blue Spinel Specimen ~

Cobalt Spinel is one of the most rare minerals in the world, and I'm happy to offer some ethically mined crystals with vivid coloring from Tanzania. This material is pure color therapy, with an amazing punch of blue when backlit. This material isn't quite suitable for cutting, which is how this small lot trickled into the industry untouched. Keep in mind these are TINY specimens, measuring 4 to 8 millimeters in most cases, and we will send them in their own individual gem jars for safe keeping and displaying.

Each X-SMALL option weighs between .5 carats and .75 carats.
Each SMALL option weighs between .75 carats and 1 carat.
Each MEDIUM option weighs between 1 carat and 1.5 carats.

This listing is for ONE (1) intuitively chosen crystal. Each piece has been handpicked and examined for quality. The photography used is a representation of our collection, the unique specimen you receive will be similar to the stones pictured and will have its own individual traits. Specimens categorized by weight don’t have specific size measurements provided, as each piece has a different shape and mass.
