Description
This is an extra large agate slice. It would look great framed or turned into a tray. 568 grams Agate is a variety of silica also sometimes known as "banded chalcedony." It is most often formed as nodules in volcanic rock. A vapor vesicle in the rock fills in over time with layers of chalcedony & crystalline quartz. When the cavity does not fill in completely there will be a geode center with the crystal points directed toward the interior of the specimen. The stone was named after the river Achates (now known as Dirillo & located in modern day Sicily) by the Greek naturalist Theophrastus. Agate has a long history of use for artistic & decorative purposes. Huge Natural Agate Geode Slice - Mineral Specimen Rocks & Crystals Art For Frame Home Decor
