Types of Natural Glass

Natural Blue Obsidian 💙 I know obsidian is usually not considered very expensive, and many people think of it simply as a type of natural glass—even when it’s ancient. There’s plenty of it available, and of course man-made versions can be created, though I’m not sure how easy or difficult that process truly is. Still, a piece this clear and this vibrant in color honestly feels almost too good to be true. I received this one for my birthday from a very reputable crystal shop in Houston, Arizona.
