What makes a natural ruby
worth wearing for a lifetime
Ruby ranks 9 on the Mohs hardness scale — just below diamond, above nearly everything else. It does not scratch easily. It does not fade. Worn daily for decades, a well-set ruby looks precisely as it did the day it was set, provided the silver is cared for around it.
Its colour comes from chromium — a trace element that does not wash out, cannot be applied, and cannot be faked by any process that produces a stone worth owning.
Synthetic rubies exist. They are chemically identical. But they lack the inclusions, the growth patterns, the slight imperfections that make a natural stone a record of its own formation. At Zanvari, every ruby in the Aatish collection is certified natural.
