Birdseye Rhyolite Lapidary Rough Rock Stone Slab
This is a beautiful unpolished stone slab of orbicular Birdseye Rhyolite that is 5.5 inches by 5.3 inches and cut thin at 3.5 mm thick.
It weighs .22 lbs. and is shown wet in the first 2 pictures.
Sometimes called Poppy Jasper, but actually a Rhyolite, this orbicular stone has red and pink dots or "poppy flowers".
This material comes from Mexico.
Rhyolite is an extrusive igneous rock formed as a deposit of volcanic ash. The ash becomes rock after being exposed to extreme heat and pressure.
Iron oxide stains create the beautiful patterns.
The name comes from the Greek word meaning "to flow" because the rock shows flow structure formed when it was molten.
