Pink chalcedony nodules, sometimes called "chalcedony desert roses," have been discovered across the southwest. They were prolific from this locale back in the 1990s, but 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 near-round specimen has a nice light pink coloration and good translucency in the top layers, with some more opaque whitish layers. This forms agate banding of white and light pink, most visible in the center of the piece, where there is a small raised ring with more subtle banding radiating out around it. The exterior has almost flesh-like wrinkled texture in areas.

UV reactivity this material has an excellent UV reaction, most pieces glowing strong green under 365nm UV light. This piece has strong, bright green fluorescence with some striations visible inside the mineral. No phosphorescence detected.
