• An off-square piece of light gray rock matrix with a triangular cluster of light pink small knobby botryoidal forms covering the middle third of the piece. There is more chalcedony with light yellow-pink tint in the bottom corner, and some white low-quality chalcedony in the upper right.
  • The specimen fluorescing strong yellow-green under UV light in low lighting. The main chalcedony has weaker green reaction with one corner vivid green.
  • Close detail view of complex banding, showing the ridges of the ropy texture of layers and faint whitish layers inside.
  • Detailed side-view of the piece, showing craggy volcanic texture to the matrix with small swirling botryoidal forms of chalcedony arranged fluidly on the surface. The chalcedony has ropy texture with some concentric banding.
  • The piece standing on-edge, the matrix thick enough to do so. Toward the center of the image, a faint agate bullseye is visible.
  • Angled view of the piece, showing more undulating and snaking chalcedony with ropy texture and bulbous forms that appear as if dripping over the edge.
  • The back of the specimen, a broken light gray matrix.
  • The piece on a measuring mat, measuring about an inch and a half square.

Pink chalcedony nodules have been discovered across the southwest, and were prolific from this locale back in the 1990s. Today are much harder to come by—at least with any size or quality. 

The material is known for its strong UV reaction and undulating ropy, botryoidal forms. Pink chalcedony often grows shapes like a nest, cup, or knobby "ear" with raised rims of concentric banding. 'Agate' refers to chalcedony with banded color, whereas this chalcedony has banded structure. It has a dynamic, fluid appearance similar to its relative hyalite, as if someone piped icing on a cake when it was still warm so it's starting to melt down the sides.

This small specimen has nice light pink coloration and good translucency, with small berry-like botryoidal forms on a light gray matrix. Studied closely, they are composed of ropy, snaking chalcedony with concentric rings visible.

UV reactivity this material has an excellent UV reaction, most pieces glowing a strong green under 365nm UV light. This piece has relatively weak reaction compared to many, with a light green glow to the pink berry formation, even using a strong 365nm UV light. A small patch of lower-quality chalcedony in one corner has a vivid geen reaction. No phosphorescence detected.
