Blue & Purple Niobium 'Mineral Specimen' Earrings

These “imagined” mineral specimen earrings were inspired by rocks I collected as a child, and specimens such as at The Natural History Museum. I have created a new, completely unique gemstone that takes crystal shapes (such as garnets) and rock textures (such as schist), and morphed them into a new, fun and almost celestial jewel. The colouring pushes the boundaries of reality on earth into something otherworldly. 

Using electricity, the hand chased shapes were anodised to create iridescent interference colours that dance in the light. This striking effect comes from niobium oxide built up on the surface using electricity in the anodising process, refracting and reflecting light to create a shifting illusion of colour. You can read more about anodising here.

Materials: Niobium and sterling silver.

Hallmarked at the Sheffield Assay Office, 2026.
