specimen number:
2062398

location:
Mysore, Karnataka, India

description:
A loose purplish red hexagonal crystal of corundum, this the variety known as Ruby. Complete all around and in good condition, brightly fluorescent.

Mysore, located in Karnataka, India, is a city with a rich history, having served as the capital of the Kingdom of Mysore from 1399 until 1947, and is globally renowned for its royal heritage and the iconic Mysore Palace. Geologically, the region rests primarily on the ancient Dharwar craton of the Indian Peninsula, which consists of deeply weathered Precambrian metamorphic and igneous rocks, including peninsular gneisses and schists that host various mineral deposits. Among these geological formations, corundum - a crystalline form of aluminum oxide - occurs naturally, with its gem-quality red variety known as ruby, which gains its vivid crimson color from trace amounts of chromium embedded within the mineral structure.
