• An egg-shaped pink chalcedony nodule, with very faint fleshy pinkish tint to the chalcedony. The bottom half is a rounded light gray matrix, with the top half a ropy nest-like form with a narrow mouth-like opening revealing a hollow interior.
  • The specimen fluorescing strong yellow-green under UV light in low lighting. The material has god even reaction.
  • Angled view of the specimen, the opening angular with a thicker rim like lips, and ropy banding down the sides. Some white agate layering is visible through the translucent chalcedony.
  • Close detail view into the opening in the nodule, with undulating edges around it and ropy botryoidal forms.
  • The reverse of the specimen, more covered in the light gray matrix with wrinkled concentric banding.
  • Close detail view of a side of the piece, showing the snaking ropy banding with small swirl marks.
  • A closer view of the banding on the reverse of the specimen, with faint agate rings visible.
  • The underside of the piece, a rounded dome of light gray rock matrix with grainy composition and a clump on one side.
  • The piece on a measuring mat, measuring about two inches long and an inch in diameter.

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 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.
