Ruby
The Inextinguishable Flame of Vitality
Also known as: Ratnaraj
About the stone
Ruby is the red variety of corundum, colored by chromium, with a name derived from Latin ruber, meaning “red.” Known since antiquity, it has no recorded single discoverer; Pliny described it in the first century AD, and Myanmar has been a source since at least 600 AD. Important locations include Myanmar’s Mogok region, Mozambique, Sri Lanka, Thailand, Vietnam, and Afghanistan. Called ratnaraj (“king of precious stones”) in Sanskrit, ruby is also marketed using the color term “pigeon’s blood” for certain vivid red stones—not a separate variety or guarantee of origin. In traditional lore, Burmese warriors believed rubies offered invincibility, while medieval Europeans associated them with health, wealth, wisdom, and success in love.

Care and handling
Ruby is very hard and durable, and ranks 9 on the Mohs scale, though a hard blow can still chip it along weak planes. Clean with warm water, mild soap, and a soft brush, then dry. Many rubies are heat-treated or fracture-filled with glass, so avoid ultrasonic cleaners, steam, acids, and harsh chemicals that could damage the filling. Store it apart from other jewelry, since it can scratch softer stones.
Individual experiences with Ruby vary, and the beliefs about amulets and protection are historical traditions rather than guarantees. Let it be a bright symbol of courage, and pair it with sound judgment and good care.
