Brazilian Agate Coasters - Set of Six

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:

This set of six Brazilian Agate Coasters is fashioned from the highest quality stone with the edges left unfinished for a natural look. An Evolution Store favorite, they come in a variety of vibrant colors, and because they are natural agate, each one is completely unique! These agate slices are an excellent gift idea, either individually, or as an entire set. We have hand-selected sets of nice coasters in all different colors just for you!

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

This natural product has been enhanced with artificial dyes. We recommend soaking these pieces in water for at least 24 hours before placing them on cloth or other stainable surfaces.
