Corundum Var. Ruby

This ruby formed within metamorphic marble, where aluminum-rich minerals recrystallized under heat and pressure to produce gem-quality corundum. Trace amounts of chromium give the crystal its signature red color. The Luc Yen region is a well-known source of fine rubies, prized for their clarity and vibrant hues.

Rich in color and naturally luminous, this specimen reflects the intense geological conditions required to form one of the most valued varieties of corundum.
