Agate, Moss Gemstone Chips

Despite popular belief, Moss Agate stones don't actually contain moss. Instead, these chalcedony-based stones display inclusions of green-colored minerals that give a grassy or mossy look. 

Most stones also feature milky-white backgrounds consisting of manganese or iron. The whitest of these stones often classifies as Tree Agate — whereas the most sought-after Moss Agate specimens sport a clear background that distinctly highlights the mossy patterns.

The tumbled stones featured in this listing all contain quartzing that’s either clear or mildly opaque. For whiter background, check out our selection of Tree Agate tumbles.
