This pair of Moss Agate Stones are ideally purchased as earrings for a wrap (no holes are drilled into these beauties), or for matching necklaces! The dendritic inclusions are beautiful - small and clustered across the whole stone! Moss agate is a semi-precious gemstone, a type of chalcedony with beautiful green, brown, or black dendritic (plant-like) inclusions that look like moss or lichen. It is formed from silicon dioxide (quartz) with iron/manganese oxides; it's prized for its connection to nature, grounding, stability, and tranquility, often called the "gardener's stone" for its association with agriculture and new beginnings.
