Obsidian is one of the most mysterious and fascinating volcanic stones created by nature deep within the Earth's fiery core. It forms when molten lava cools rapidly, producing a unique natural material with a glass-like texture and deep, intense color.
Often referred to as natural volcanic glass, obsidian has an amorphous structure rather than a traditional crystalline form. This distinctive structure gives the stone its remarkable appearance—rich black tones, a mirror-like shine, and subtle color variations.
Today, obsidian jewelry holds a special place in the world of fine accessories. This semi-precious stone is valued not only for its elegant beauty but also for its symbolic and energetic significance.
The history of obsidian stretches back thousands of years. Ancient civilizations believed the stone possessed powerful properties and used it in both everyday objects and ceremonial artifacts.
Obsidian was first described by the ancient Greek philosopher and naturalist Theophrastus, who lived in the 4th–3rd centuries BC. Archaeological discoveries, however, reveal that obsidian was already widely used during the Stone Age to produce knives, tools, and spearheads due to its incredibly sharp edges.
The name obsidian comes from an ancient Roman legend. According to tradition, the stone was first brought to Rome by a warrior named Obsius, and the mineral was later named in his honor.
Throughout history, obsidian has been surrounded by fascinating myths and legends.
Caucasian mythology
In some traditions, obsidian was believed to be fragments of the devil’s claws, due to its dark color and sharp edges resembling volcanic fire.
The Apache legend
In North America, a famous legend states that obsidian stones are the tears of ancient Apache warriors that hardened in volcanic lava. These stones are still known today as “Apache Tears.”
European tradition
In Hungary, obsidian was sometimes referred to as “lux sapphire” because its brilliant shine resembled precious gemstones.
Obsidian appears in several fascinating natural varieties.
A deep black stone with white crystal inclusions that resemble snowflakes.
A rare type displaying shimmering layers of red, green, blue, and golden hues when exposed to light.
A black variety with rounded patterns formed due to high magnetite content.
Obsidian is primarily found in volcanically active regions.
Major deposits exist in:
South America — Mexico, Peru, Ecuador
Japan — especially the island of Hokkaido
New Zealand, Iceland, and Kenya
The United States — particularly Nevada, Arizona, and California

In Georgia, obsidian has been known since ancient times and was poetically referred to as a “fragment of the sky.” A notable deposit is located near Paravani Lake, where unique black stones with reddish inclusions can be found.
