What is Rhyolite?
Rhyolite is a volcanic rock sometimes confused with jasper. Rhyolitic lavas form thick flows or steep-sided piles called lava domes. Precious gem deposits commonly occur in rhyolite’s gas pockets known as vugs. It is rarely used in construction or manufacturing because it fractures easily but is sometimes used to produce crushed stone for road fill.
Uses & Applications
Rhyolite is a hard stone that has been used in construction since prehistoric times. The stone is easy to shape and can hold a sharp edge. Ancient humans often fashioned knives out of rhyolite. Crushing the stone turns it into abrasive pumice that’s used in concrete.
Healing Properties
Rhyolite is an excellent stone for the procrastinator who needs a little encouragement. It works on the Crown and Third Eye chakras to stimulate creativity and insightful thinking. Believers say it encourages progress and change while boosting self-esteem and confidence. Use it for meditation, wear it, or keep it in the home.
