Spinels were long hiding in plain sight.


For centuries, red spinel was confused with ruby, because both can show a deep, fiery red.
Even in rough, they can occur together in similar host rocks and look surprisingly alike.

The most important deposits are located in Myanmar, Vietnam, Sri Lanka, Tajikistan, Tanzania, and Afghanistan.
Every spinel bears microscopic traces of its origin, shaped by metamorphic rocks such as marble and other aluminum-rich environments.
Laboratories use these features, together with optical testing, to confirm authenticity and separate spinel from look-alike gems.
