• A pink chalcedony nodule with two flat, rounded lumps of chalcedony side-by-side an light gray matrix, with faint pink color and a more opaque white center. The surface of the pieces is ropy with fluid patterns like lava.
  • The specimen fluorescing strong yellow-green under UV light in low lighting. The fluorescence is strongest in the center of the pieces, with less reaction toward the base.
  • Detail view of the piece, emphasizing the translucency of the chalcedony and showing the swirling pattern on the surface. One of the circles has some thin white overgrowth on the surface.
  • Close detail side-view of the two chalcedony formations, excellent banding layers with the edge bulbous and thick and almost fleshy texture.
  • Detailed end-view of the specimen, showing a knob on one end with swooping rings of banding radiating out from it.
  • The piece on its side, showing a wedge of gray-tan rock matrix with the two domes on the right-hand face.
  • Side-view of the piece held up, showing good translucency in the chalcedony, and a thick rim of matrix bordering the two domes.
  • The underside of the specimen, plain broken rocky matrix with light tan-gray color and some rounded forms to it.
  • The piece on a measuring mat, measuring about an inch and a half long, and a inch across.

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 is a piece of light tan-gray matrix featuring two flat domes of chalcedony, like a pair of bongo drums (or half-melted soft-serve). The chalcedony has very light pink coloration and good translucency, with some more opaque whitish layers visible inside. The surface has a swirling ropy and melted appearance.

UV reactivity this material has an excellent UV reaction, most pieces glowing strong green under 365nm UV light. This piece has a very good reaction, with fluorescence brightest in the center of the circles, and a lighter reaction in the sides and base. No phosphorescence detected.
