✡Black obsidian is formed by the rapid cooling of lava or magma that has high silica content. As the lava cools quickly, it solidifies into a black, glassy rock without crystallizing, creating the unique properties of obsidian.
Note:
1)Crack-like lines, fissures, uneven texture or beads and crystals are natural.
2)If a crystal breaks or snaps in half or in pieces, or sometimes could break while in transport, it does not affect the quality of the crystal. Crystals are naturally brittle and a broken crystal just means now you have more than one piece. Any crystal piece you have is any way broken from a larger chunk.
