Collection: Corundum

Corundum, composed of crystalline aluminum oxide with occasional traces of iron, titanium, vanadium, and chromium, serves as a mineral integral to rock formation. While inherently transparent, its color can vary based on the inclusion of transition metal impurities within its crystalline structure.

Corundum boasts two main gem varieties: ruby and sapphire. The red hue in rubies is attributed to the presence of chromium, while sapphires exhibit a spectrum of colors influenced by the specific transition metal present. Notably, a rare subtype of sapphire, known as padparadscha sapphire, displays a distinctive pink-orange coloration.
