• A pink chalcedony nodule with stacked thick ropy banding on a small piece of light gray matrix. The top and bottom layers have more translucency and a light pinkish coloration, and some undulating white layers are visible in the center.
  • The specimen fluorescing strong yellow-green under UV light in low lighting. The upper layers stronger reaction than those in the middle that are milkier, and the base is green again.
  • A close detail view of the side of the piece with this ropy layers stacked tall, with swirling botryoidal forms along the base where it attaches to the matrix.
  • End-view of the specimen, a bulbous striated formation on the top with fluid flow as if dripping over the side of the piece.
  • End-view of the piece, showing the undulating layering, more pink-tinted and the top and white in the center.
  • End-view of the specimen, with swirling ayers and botryoidal forms along the base. The chalcedony has some pock-holes in the surface.
  • A more distant view of the specimen self-standing, showing the side with the bulbous pink formation and rippling layers below it.
  • A more distant view of the specimen, showing the bulbous side. The angle shows a more white side with thin complex banding.
  • The underside of the piece, a rounded broken light gray rock matrix.
  • The piece on a measuring mat, measuring a little over an inch square.

Pink chalcedony nodules have been discovered across the southwest, and were prolific from this locale back in the 1990s. 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.
