Agates, a form of quartz, have been used as gemstones for thousands of years. They were some of the earliest stones fashioned by people. We love the translucent nature and the banded patterns that are naturally created by ground waters seeping into the volcanic cavities where these stones are found. We celebrate the natural beauty of the stone! Each piece is unique and one of a kind. These coasters are trendy and will add fashionable flair to your table.
