Description
Coyamito Agate – Unpolished Nodule
A beautiful Coyamito Agate nodule featuring distinct natural banding in soft gray, cream, white, and muted reddish-brown tones. The exposed face reveals bold concentric layers surrounding a large central crystal-lined cavity, creating a striking contrast between the agate banding and crystalline interior. The piece remains unpolished, preserving its natural character and formation.
