The banding is well-defined and consistent, giving the specimen strong visual presence from every angle.\u003c\/p\u003e\u003cp\u003eThe freeform polish is clean and even, applied by hand to enhance pattern depth without masking the stone's organic silhouette. Luster is vitreous, characteristic of fine microcrystalline quartz, and the surface holds a smooth, glassy finish across all polished faces.\u003c\/p\u003e\u003cp\u003eAgate forms through silica-rich fluid infilling voids in host rock over long periods, depositing in rhythmic layers that produce the banding this material is prized for. Black banded agate achieves its dark tones from iron and manganese inclusions locked into the silica matrix during formation.\u003c\/p\u003e\u003cp\u003eAt lapidary grade with display-quality polish, this piece suits a collector's shelf or a working lapidary's reference collection.
