Chapter one
History and rediscovery
Red and pink spinel adorned the treasures of Mughal emperors and European monarchs, yet for centuries it was mistaken for ruby. Gemologists only told the two apart in the 18th century.
Many historic “rubies”, including the Black Prince’s Ruby in the British Imperial State Crown, are in fact spinel. Its name likely comes from the Latin spina, thorn, after the pointed shape of its crystals.
In ancient Burma, warriors wore red spinel for protection and courage in battle. Today collectors value its natural purity and untreated color, and connoisseurs prize its subtle color variation and rare transparency.
The most famous “ruby” in the British crown is a spinel.
