Black Banded Agate Freeform Polished Specimen 1.22 lbs — Collector Display Piece Lapidary Grade

This black banded agate freeform weighs 1.22 lbs and carries bold, high-contrast layering — jet black dominant bands alternate with warm caramel brown and cream white secondary zones throughout the piece. The banding is well-defined and consistent, giving the specimen strong visual presence from every angle.

The 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.

Agate 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.

At lapidary grade with display-quality polish, this piece suits a collector's shelf or a working lapidary's reference collection. One specimen, one of a kind. Weight: 1.22 lbs.
