Large Natural Brazilian Agate Slices

The Science:

Agate is a type of chalcedony - a cryptocrystalline variety of silica. Often associated with volcanic activity, it is also found in metamorphic and fossiliferous rock. Agate forms in rock cavities - whether created by bubbles or volatile material in volcanic lava or the decomposition of an item such as a seashell - which fill with molecules of silica over time. Variations in the mineral content result in an array of colors and sometimes create striking banded patterns. Agate was named for the Achates river (in what is now Italy) by a Greek philosopher named Theophrastus in approximately 350BC. Historically used for carvings, including cameos, beads and cabochons, Agate was in commercial use as early as 3,000 years ago.

The Story:

These are select 4-5 inch slices of natural Brazilian Agate in varying tones from black to brown and amber to cool greys. Their patterns are equally varied with rings and swirls - each is as unique as a fingerprint! These translucent pieces have been polished smooth and the edges have been left unfinished for a natural look. They may be used as slightly oversize coasters or small serving plates, and they look great as objects for display!

Individual shapes and colors vary but your item will resemble the pictured examples.
