Origin & story
For centuries spinel was mistaken for ruby in the world's great crown jewels. Today it is celebrated in its own right for its pure, glowing colours and exceptional brilliance.
East African and Asian deposits produce fine spinel in red, pink, and rare cobalt blue. SOMSTONE evaluates each crystal for colour, clarity, and cut potential.
