Carnelian Agate Nodule
Rocks, Fossils & Minerals

Carnelian Agate Nodule

This item is a natural, water-worn carnelian agate nodule, displaying a smooth but unpolished waxy luster characteristic of chalcedony. The specimen measures approximately 1.5 to 2 inches in diameter and fits comfortably in the palm of a hand. Its color palette is dominated by rich, translucent burnt orange and honey-amber tones, with sections of clear to smoky-grey microcrystalline quartz. The internal structure shows complex natural inclusions, feathering, and subtle banding that suggests a volcanic origin. The surface exhibits a natural patina with minor white pitting and micro-fractures known as 'chatter marks,' which indicate it was likely tumbled in a riverbed or high-energy environment over geological timescales. There are no man-made markings, signatures, or alterations; its value lies in its raw, organic form and the saturation of its iron-oxide induced coloration. The transparency is variable, with deep orange centers appearing nearly opaque and the edges allowing significant light transmission, highlighting the stone's internal depth and structural integrity.
