• DETAILED DESCRIPTION

Moss Agate is an interesting variety of chalcedony, a cryptocrystalline form of quartz. Unlike classic Agates, it usually does not show the typical layering, but is characterized by the presence of dendritic inclusions resembling moss or tree branches. These patterns are not of organic origin, but derive from iron and manganese oxides. Moss Agate is most commonly found in translucent or milky white hues with green, brown, black or red inclusions. Its hardness on the Mohs scale is between 6.5 and 7, equivalent to that of common quartz. It has a waxy to dull luster and is semi-transparent or translucent. Important deposits of moss agate are found in India, Brazil, the United States (especially in Montana, Oregon and Idaho), Madagascar and Russia.
