Agate is a chalcedony with various colored areas. In the agates family we can fined: agate, dendritic agate, moss agate, common chalcedony, chrysoprase, carnelian, heliotrope, jasper, onyx and sardoine.

The colors of the agates are those of the chalcedony constituents: white, gray blue, green gray, yellow brown, brown, red brown. Besides its use as adornment (necklaces, cabochon), for the cameos and for the intaglio, the agate is often shaped in dishes.

Agate has a hardness of 6.5 / 7 on the Mohs scale.

Nevertheless, always bare in mind that all stones are fragile! even the diamond ....

Agate can be mounted in ring, earrings or pendant.
