Spinel – The Hidden Treasure of Hunza
The valleys of Hunza in northern Pakistan are home to spinels of exceptional clarity and brilliance. For centuries, spinel was mistaken for ruby and sapphire, with some of history’s greatest crown jewels — once believed to house rubies — actually containing spinels. Today, Hunza spinels are recognized in their own right, admired for their vivid colors and resilience.
