Agate is the banded form of Chalcedony, a micro-crystalline variety of Quartz. It forms in nodules, growing from the outer walls inward, creating beautiful translucent banding. Older Agates may appear opaque and less banded due to weathering and natural transformations within the minerals. Our high-quality Agate is mined directly from our Norcross-Madagascar (NMG) Agate Fields located in Ambarijeby, Madagascar. Rough agate includes our Agate Block Rough (larger pieces) and Agate Garden Decor Rough (smaller pieces for tumbling and jewelry making). Available in 7 varieties: Banded Agate, Banded Carnelian Agate, Dendritic Agate, Druzy Agate, Multicolor Agate, Ice Clear Agate and Grey Agate. Agate has a gentle energy that is perfect for your metaphysical needs.
