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 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.
