Magnesite Cabochons

Magnesite is a naturally occurring magnesium carbonate mineral with white-to-cream body color and dark iron-oxide matrix veining. The contrast between the white ground and dark matrix is natural to the stone. A clean, high-contrast neutral that pairs well with sterling silver and copper, ideal for jewelry makers who want an organic pattern without color competition.

Polished Cabochons Only

Every stone here is a finished, loose cabochon: cut, shaped and polished, ready to set. We don't sell raw or rough material. Each listing is priced for the full lot pictured, shown next to a US dime (18mm) for scale.
