DYED AGATE SLICE -ABLUE COLOR – NATURAL BORDER Home / Carved Minerals / Fossils

Great gift for Valentines Day for rock lovers❣️ Agates are a type of chalcedony, a milky form of quartz, that appears in a striking banded formation that people have found aesthetically pleasing for centuries.
Chemically, it is identical to quartz, amethyst, and carnelians, but because it forms in a different way, this stone looks radically different. Like all forms of chalcedony, its chemical formula is Si02, and the colors come from impurities in the silicon dioxide. In addition to coming in a range of stunning colors in nature, the highly porous stone is also sometimes dyed to be more vivid in color.
The outer layer of the stone tends to turn dark and crusty, but the layers inside form rich bands of color that can be cut in cross section and polished for use in jewelry.
Brazil, Uruguay, and the Western United States are all sources for raw agate.
