Personal Note From Natural Gems Belgium:

Obsidian is produced from felsic lava, rich in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium. Obsidian is hard, brittle, and amorphous. This specific type is known as midnight lace obsidian. Midnight Lace Obsidian is a brand-new type of obsidian gemstones on the world-market and thanks to its fantastic variety of patterns it's also a real eye-catcher.
