Rhyolite is a felsic extrusive rock. Due to the high silica content, rhyolite lava is very viscous. It contains grains so small that they are difficult to observe without a lens. Rhyolite is made up of quartz, plagioclase, and sanidine, with minor amounts of hornblende and biotite. Trapped gases often produce vugs in the rock. These often contain crystals, opal, or glassy material.
As a healing stone, rhyolite helps express confidence and a loving nature. It also assists in placing the influence of others into perspective and calms the soul through the heart. In antiquity, rhodonite was given to travellers as a protective stone, it was said to warn them of imminent danger by causing the heartbeat to accelerate suddenly.
Beautiful and useful too! Pendulums are used much the same way as applied kinesiology or muscle testing to help determine the answer to a question.
