Moss Agate is a naturally occurring gemstone, not man-made. It’s a form of chalcedony with distinctive green inclusions that resemble moss or foliage. These inclusions are created by minerals and other materials during the stone’s formation process over thousands of years. Moss Agate’s unique appearance makes it a sought-after gem for jewelry and decorative items. Unlike lab-created gemstones, Moss Agate’s beauty comes from the intricate patterns formed in nature.
