AGATE STONE belongs to the silicate group. It contains silicon and has the same chemical formula as Quartz or Amethyst, SiO ₂ .
It is a microcrystalline variety of Chalcedony, mainly in massive form. The hardness of Agate is equal to 7/10 on the Mohs scale (10 for diamond) and its density is 2.7 (1 for water). The line on the porcelain is white. Polyhedral Agates are a natural variety displaying an angular geometric construction.
AGATE STONE is often sold in slices and artificially colored, but it can also be found naturally blue or green.
That of other agates varies according to their concentric bands, from colorless to white, passing through blue, brown, green and gray.

The name Agate comes from the Achates River in Sicily. This river is now called the Dirillo .
