Why do Indians call obsidian Apache tears?

Legend has it that a team of Apache tribe was ambushed by the enemy, outnumbered and wiped out. When the bad news came, the crying tears of family members fell to the ground and turned into small black stones, hence the name "Tears of Apache". ?

Obsidian is a kind of natural glass. It is caused by the rapid cooling and condensation of volcanic lava, and the crystal structure does not have enough time to grow. Obsidian usually appears on the periphery of lava flows because it cools fastest.

Main component: silica, hardness: 5, specific gravity: 2.339-2.527, refractive index: 1.48- 1.5 1, water content: 1-2%, chemical composition: silica (H2O).

Extended data:

Obsidian is a kind of igneous rock, not crystal, but crystal, although the composition of obsidian is mainly SiO2. Obsidian is amorphous and microcrystalline colloidal silica, not glass. It is formed by the rapid cooling of volcanic lava, so it is difficult to crystallize. It is an amorphous gem with conchoidal fracture.

Obsidian may be all monochrome, stripes or spots. The presence of small crystals is an identifying feature. Some inclusions of obsidian have nonmetallic luster, while some internal bubbles or crystals produce "snowflake" effect (namely snowflake obsidian) or are regarded as flashing rainbow color. The most famous is rainbow obsidian with rainbow flash.

And some items are oval, which forms the so-called monocular obsidian or binocular obsidian. However, from the price point of view, rainbow monocular obsidian and rainbow binocular obsidian are the most expensive, because in addition to the relatively scarce output, the appearance is also quite beautiful.

In addition, there is another kind of ice obsidian. However, what is ice obsidian? Obsidian, an ice seed, comes from Iceland's Haikela volcano and is a sacred object bred by volcanic eruption during the Ice Age.

Age is the oldest obsidian. It absorbs the essence of day and night in the purest period, and breeds the purest energy between heaven and earth. It is a very rare energy stone with high transparency and is the best in obsidian. The characteristic of ice obsidian is that its surface is pure black, and it turns brown after strong light irradiation, so it is ice obsidian.
