The name "Obsidian" is derived from the name "Obsius" of an ancient Roman explorer. Obsidian is an amorphous gemstone, a naturally occurring volcanic glass, and is considered the "national stone" of Mexico. Obsidian is formed when the temperature outside the lava falls rapidly so that the magma containing silica cools and solidifies quickly without allowing enough time for the mineral crystals to grow and form a glassy substance. Because of this unique formation process, obsidian also contains 1% to 2% water inside. Obsidian is an igneous rock found mostly in areas with volcanic activity, such as Hawaii in the United States, Japan, and Java in Indonesia.
The appearance of pure obsidian is usually black. Still, it varies depending on the presence of inclusions, such as iron and other transitional elements that may make the obsidian dark brown to black, with a few exceptions such as red, green, orange, yellow and gray.
Obsidian is hard but brittle and fragile, so it has sharp edges when fractured. Because of this property, obsidian was often used to make cutting and piercing tools and was also used as the blade for surgical knives. Obsidian jewelry is now commonly found in the marketplace, mostly beaded and strung as bracelets or as sculptural art pieces for wear or indoor display.
Types of Obsidian
Most people think of obsidian as pure black, but in addition to black, obsidian may also exhibit different colours, textures, spots or special optical phenomena. There are many types of obsidian in commerce, mainly black in colour, depending on its appearance.
Pure black obsidian, deep and understated, without any hint of color, with a delicate and smooth texture, without any rough crystalline particles, and with a lustrous and lustrous surface, without cracks or veins. This type of obsidian has the largest production and is the most common one in the market.
- Rainbow Obsidian
Rainbow Obsidian is a type of obsidian that has a rainbow of flashes of light that can be seen in sunlight or bright light. Rainbow obsidian is lighter in color, giving it a translucent visual effect. The difference between single-eyed obsidian, which has a concentric eye, and double-eyed obsidian, which has a concentric eye on the front and back, is that they are the best of the obsidian types.
- Golden Sheen Obsidian
Golden Sheen Obsidian, also known as Golden Obsidian, has a brilliant black base, but when illuminated by a light source, it exhibits a visual effect resembling a golden halo, which is made up of sandy gold dots, like a thin layer of golden quicksand, densely packed on the surface of the stone.
- Silver Sheen Obsidian
Silver Sheen Obsidian, also known as Silver Obsidian or Silver Sparkle Obsidian, is a silvery sandy stone that appears like a galaxy in the night sky, recessed and serene when illuminated.
- Snowflake Obsidian
When quartz crystals are formed on the surface of obsidian rocks, it has a white or gray pattern, just like snowflakes falling on the surface of the stone, with contrasting colours.
- Velvet Obsidian
Velvet Obsidian is characterized by velvety light and shadow changes as the angles change and is a relatively rare type of obsidian with variable colours and intricate patterns.
- Mahogany Obsidian
Mahogany Obsidian, also known as Mahogany Obsidian, contains hematite and magnetite, and although it has the word "red" in its name, it is also a type of obsidian. It is characterized by red patches on the stone, creating a strong contrast between red and black.
- Cat's Eye Obsidian
The Cat's Eye Effect is the result of the growth of gemstone crystals that contain microscopic fibrous gaseous, liquid or solid inclusions arranged in parallel, which, when cut into a curved shape and illuminated, form a luminous ribbon of satin-like light that resembles the gaze of a cat's eye.
The Legend of Obsidian
Legend has it that long ago, a group of white men occupied Indian land and drove them to a barren area. Later, 75 brave Apache warriors went out to fight in hopes of reclaiming their land, but 50 died in the first wave of fire, and the remaining 25 survivors were forced to a cliff. The Apache warriors were determined to jump off the cliff rather than die at the hands of the whites, losing all the soldiers and no survivors.
The wives of the soldiers shed tears of sorrow when they learned of the tragic news, and when the tears fell to the ground, they transformed into small black stones, hence the name "Apache Tears". It is said that whoever owns this black stone will never cry with grief because the Apache maidens have dried all their tears for the owner of the obsidian.
