Obsidian flake heart pendant natural stone 15 mm, stone of salvation

A stone known as volcanic glass.

It is formed by the rapid cooling of hot lava in water on the Earth's surface, with the entire process occurring so quickly that individual minerals do not have time to crystallize. Rainbow obsidian comes from Mexico and has a dark, finely striped exterior. With the correct orientation of the stone, rainbow effects are also created on its layers due to the refraction of light.

From a compositional standpoint, it is a natural form of silica glass.

It has been used by humans since the Stone Age, when hunters made the tips of their weapons from its sharp fragments.

He was highly valued among the ancient Aztecs, who referred to him as the "Stone of the Gods." Their sacred dagger, intended for the infamous ritual of performing human sacrifices to the gods, was made from this very stone.

Limitation: Obsidian resists most acids.

However, it is fragile, so it requires careful handling.
