• An elongated pink chalcedony nodule with a small angular opening around a hollow interior, fluid ropy banding in concentric rings down the sides. The swirling layers quickly become blobby botryoidal forms around the sides. There is a dark piece of rock lodged deep inside the interior.
  • The specimen fluorescing strong yellow-green under UV light in low lighting. The layers toward the top of the opening have stronger reaction.
  • Close detail view of a side of the piece with quite a few small round botryoidal forms with rings of layers and slightly swirling pattern. The rim of the opening has distinct banding like lips.
  • Detailed side-view of the specimen, gray matrix visible at bottom right. The side has super ropy layers like a lave flow, with botryoidal forms along the right side. There is some light brown staining at the rim.
  • Full view of the specimen, the opening positioned off to the side. The chalcedony is more pink with good translucency towards the base near the matrix.
  • The back of the piece, some botryoidal forms and banding visible, partially covered with a light gray matrix.
  • A closer view of the back of the piece, with bumpy botryoidal forms along the edge of the matrix, the larger bumps ringed with rippling banding.
  • The piece on a measuring mat, measuring about an inch and a three quarters in diameter.
  • A more distant view of the piece, the interior shaded but with some glow of light traveling through the translucent chalcedony.
  • Another distant view of the specimen, showing light illuminating the translucent light pink chalcedony along the exterior of the piece, especially around the small botryoidal forms.

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 flat "ear" of a specimen has a small opening and shallow cavity. The piece has a nice light pink coloration and good translucency in the top layers, with some more opaque whitish layers inside, creating faint agate banding. The exterior details are well-formed, with ropy banding rippling around lumpy botryoidal growth.

UV reactivity this material has an excellent UV reaction, most pieces glowing a strong green under 365nm UV light. The translucent material at the top of this piece has strong UV reaction, as does the interior, with the lower banding fainter. There is a small material fluorescing orange, visible through the pink chalcedony (in the botryoidal form just to the left of my thumbnail). No phosphorescence detected.
