Green Rhyolite Stone 10.8 oz gallet measures 2.75 inches by 2.62 inches by 2 inches. It's paperweight size.
Rhyolite is an igneous rock. Igneous comes from the word ignis, which means fire in Latin. Think ignite. It has the properties of the fire signs in astrology. It has the same composition as granite, but it is extrusive, meaning it is volcanically-formed as opposed to granite, which is intrusive, meaning it forms below the earth's surface. As Rhyolite cools, it forms a bunch of tiny, even microscopic in size, crystals. If it didn't form any crystals, it would actually be obsidian instead of rhyolite. Granite, which forms inside the magma, cools much more slowly, and tends to produce larger crystals. If Rhyolite has a lot of holes (vesicules) in it, it is pumice.
Rhyolite is also known as wonderstone. It clears cloudiness in your inner vision so that you can visualize what you really want. It resonates with both the astral and causal planes so that you can see everything that is waiting to come to you that you ordinarily can't see. No wonder it's called wonderstone.
