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 structure like a stack of flapjacks, with nice light pink coloration and good translucency in the top layers. The middle layers have more opaque whitish banding. The pink chalcedony is thick, with a small amount of light gray matrix on the base.

UV reactivity this material has an excellent UV reaction, most pieces glowing a strong green under 365nm UV light. The more translucent material on this piece has stronger UV reaction, making it look like a hamburger of green, light whitish and more green when fluorescing.
