Gem watch: Are spinels the next ‘big thing?’

Gem watch: Are spinels the next ‘big thing?’

By Lauriane Lognay

There’s no doubt, spinels, a gem often confused with rubies and sapphires, are gaining popularity. With its hardness of eight on the Mohs scale ranging from transparent to opaque, this gemstone will be taking the market by storm in no time.

What are spinels?

Its name comes from the Latin term ‘spina,’ meaning arrow because of its shape when in the rough. Most of the time, rough spinels contain well-formed octahedron, or double pyramid inclusions, and are frequently found in African and Middle Eastern countries including Sri Lanka, Tanzania, and Afghanistan. Before modern science, no one could tell the difference between a spinel and a ruby as the colours and chemical compositions are extremely similar. It wasn’t until the late-18th century when we developed technology to distinguish spinel as a separate mineral from ruby. However, in the late-1500s, gem traders in Myanmar were first to recognize spinel as distinctly different.
