Rhyolite heart and flame pendants.
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 metaphysical properties:
Rhyolite promotes a feeling of stability, a strong foundation, and an inclination to persevere. It is great when you need more discipline. Wear it when starting a diet or new exercise regime. Great for students with a heavy unit load.
If you feel you need help embracing the system, this is also a great crystal for you. It helps you see the good in the establishment. If you want to be rich, but fight the system that is based on wealth, you need Rhyolite. Its energy enables you to fit in and work for the evolution you believe in as part of the whole.
