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 looks like an egg in a light gray matrix "egg cup." Thick lava-like ropy banding create the raised cup of chalcedony with a hollow interior. The piece has faint pink coloration, with some more opaque whitish layers visible inside creating subtle agate banding. 

UV reactivity this material has an excellent UV reaction, most pieces glowing a strong green under 365nm UV light. This piece has very good reaction, with the interior glowing the most vivid green, and the milky material on the side a bit less reactive. No phosphorescence detected.
