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 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.
