Chinese Style Red Agate Beaded with wood

Agate is a common, translucent to opaque banded variety of chalcedony (microcrystalline quartz) that forms in volcanic or sedimentary rock cavities. Known for its distinct, concentric, or horizontal colored bands, it has a hardness of 6.5–7 on the Mohs scale, making it durable for jewelry, carvings, and decor.
