Obsidian is the stone of the depths: a black glass born in volcanic fire, so glossy that humanity's very first mirrors were cut from it. It's long been known as one of the great stones of protection and truth, and it's still one of the most sought-after stones in obsidian jewelry today. Here's a look at its geology, its history, its meaning and properties, and how to wear it and care for it.
A volcanic glass, not a crystal
Obsidian isn't a crystallized mineral. It's a natural volcanic glass. It forms when lava that's very rich in silica cools so fast, on contact with air or water, that crystals don't have time to grow. The material freezes into an amorphous mass, smooth and glossy, with a hardness of 5 to 5.5 on the Mohs scale. It breaks with what's called a conchoidal fracture, which leaves incredibly sharp edges. That's why obsidian is one of the sharpest materials nature has ever given us.
Depending on what's trapped inside it, obsidian comes in many varieties. Deep black is the best known, but there's also golden or silver obsidian with a fine metallic sheen, rainbow obsidian with its iridescent rings, snowflake obsidian speckled with pale gray, and Apache tear, small and semi-translucent. It's found mainly in Mexico, the United States, Iceland, Armenia and Ecuador, wherever volcanoes have left their mark.
Origins: name and legends
Obsidian is named after Obsius, an ancient Roman who, according to Pliny the Elder, brought a dark, glossy stone back from Ethiopia. It was called "Lapis Obsidianus," the stone of Obsius. But its story starts long before Rome. As far back as prehistoric times, people shaped obsidian into knives, arrowheads and pendants, prized above all for their unmatched edge.
Obsidian reached its full symbolic power with the Aztecs. The stone carvers of ancient Mexico made ceremonial blades and polished mirrors from it. These were the emblems of Tezcatlipoca, a major figure in Aztec mythology known as the "Smoking Mirror." The name says it all: in the stone's gleaming darkness, people saw reflected what the everyday eye would rather avoid. As for the Apache tear, legend says it was born from the tears Apache women shed after losing their warriors, frozen forever in the rock.
Obsidian meaning and symbolism
Obsidian stands for protection and inner truth. Like a dark mirror, it asks you to look yourself in the eye, honestly and without excuses, and to draw a clear line between yourself and whatever weighs you down. It's linked to the root chakra, the center of grounding and a sense of inner security. To learn more about this energy center, read our guide to the root chakra or our complete guide to the 7 chakras.
When it comes to zodiac signs, it's often named as the stone of Scorpio, Capricorn and Sagittarius, three signs that aren't afraid to dig deep or aim high.
Obsidian properties in crystal lore
Above all, obsidian is a stone of protection. It's described as a dark shield you turn to when you want to block out heavy influences and symbolically cut ties with whatever you'd rather leave behind. It's the stone people choose when they're in a heavy environment or going through a time when they feel exposed.
Obsidian is also known as a mirror of the soul. It's said to bring what you keep quiet up to the surface, so you can let it go. It's considered an intense stone, sometimes a demanding one. Many people suggest easing into it, wearing it a few hours a day at first before making it an everyday companion.
In crystal lore, obsidian protects, grounds and invites inner truth, with the unflinching depth of stones born of fire.

How to clean obsidian and keep it shiny
Obsidian is glass. A quick rinse under clear water won't hurt it, but knocks can chip its sharp edges. Rinse it for a few seconds under running water, dry it with a soft cloth, and store it away from harder stones.
To bring back its mirror shine, a dry microfiber cloth, the kind you use for glasses, works wonders. Keep it out of long, direct sun and away from heat. Between wears, let it rest overnight on your nightstand, true to its night-loving nature, then slip it back into its pouch. You'll find all our tips in our article on cleaning and caring for your crystals.
