Description
Locality: Rajasthan, India
Description: These tumbled ruby specimens from India are typically opaque to semi-opaque with deep red, maroon, or almost blackish-red tones. Because they are heavily included, they do not display gem transparency but instead show a dense, earthy body color with occasional flashes of crimson in strong light. When tumbled, the stones develop a smooth, waxy-to-vitreous polish that highlights their internal structure and natural fractures. A notable characteristic of many ruby specimens from India is their strong UV reactivity, often glowing a bright to dull red under ultraviolet light due to chromium content within the crystal lattice.
Rubies from India have been known and worked for centuries, often occurring in metamorphic rock formations where aluminum-rich minerals are subjected to intense heat and pressure. Ruby-bearing corundum is found in various regions of India, often in smaller or more heavily included forms. These deposits typically yield material better suited for lapidary, carving, and tumbling rather than faceting, which makes them popular among collectors.
