{"title":"Chalcedony","description":"\u003cspan\u003eChalcedony is a cryptocrystalline form of silica, composed of very fine inter growths of the minerals quartz and moganite, these are both silica minerals.

It can assume a wide range of colors, but those most commonly seen are white to gray, grayish-blue or a shade of brown ranging from pale to nearly black.
