Black Ruby Tumbled Stone - 20-35 mm

Black Ruby Tumbled Stone, a smooth polished piece of deep red ruby set within a dark host rock, the rich red showing against the near-black matrix. Each stone is tumbled to a rounded shape and a soft polish that brings out the contrast. It has a comfortable, solid presence in the hand.

Black Ruby is traditionally associated with strength, drive and grounded vitality, and is commonly used as an energizing, confidence-building stone. People often carry it for a sense of resilience, keep it close during demanding stretches, or hold it for a steady lift in motivation. The ruby-in-matrix look makes it a striking, grounding piece.

Each Black Ruby Tumbled Stone is natural, so the amount of visible red ruby against the dark matrix varies from piece to piece.

Geological Information
Ruby is the red variety of corundum, aluminium oxide at Mohs 9, second only to diamond in hardness, with its red colour from chromium. In this material the ruby occurs as opaque crystals within a darker host rock, giving the black-and-red appearance. Heat treatment is near-universal in gem-quality ruby, though opaque matrix material like this is typically untreated; treatment status is worth confirming. Commercial matrix ruby is sourced from India, with gem ruby coming chiefly from Myanmar and across Southeast Asia and East Africa.

Every piece is inspected and photographed to reflect its true character; however, lighting conditions, screen settings, and natural variation may cause slight differences in appearance.
