The Great Imperial Crown made for Catherine the Great in 1762 is finished at its highest point with a red spinel, set directly beneath the diamond cross.
The Russian court gave the summit of its most important object to spinel, and the stone is still there today. This is a red spinel; watch the colour hold steady while the stone turns.
