A natural sphalerite sphere, polished to reveal the mineral's extraordinary refractive qualities. Sphalerite has one of the highest refractive indices of any non-metallic mineral — higher even than diamond — giving it an exceptional brilliance and fire that makes it a prized collector's specimen.

This sphere showcases sphalerite's characteristic warm brown, amber, and honey tones, with a glassy lustre and subtle translucency that shifts beautifully under different lighting conditions. Sphalerite is a zinc sulphide mineral found in hydrothermal ore deposits worldwide.

• Each piece is unique — colour, translucency, and surface texture will vary

As with all natural stones, slight variations in colour and surface texture are part of what makes each piece entirely its own.
