18 Various Kinds of Opals
When most people think of an opal, they might think of a milky-colored stone containing a rainbow of stripes or flecks inside it. What many people don’t know is that they are incredibly diverse in appearance, and are not actually minerals. Opals are a solid, amorphous form of silica, and are classified as “mineraloids”. Like other mineraloids, such as amber, pearl, and obsidian, they lack structural order, or “crystallinity”.

Uhh…that last image isn’t from the Aladdin film…It’s from a porn comic. It’s been cropped, in the full image he’s being blown by Hercules.
