• Angled view of a pink chalcedony nodule with close to no apparent color, slightly fleshy tinted. It is shaped like an open clamshell with wavy edges, and waxy skin-like texture. The formation is atop an irregular angular piece of gray-brown matrix.
  • The specimen fluorescing strong yellow-green under UV light in low lighting. The piece has excellent, even reaction, with agate rings of milky appearance. There is a band of chalcedony running through the matrix that fluoresces an even more vivid yellow green.
  • Close detail view of a pink chalcedony formation with very faint pinkish color. The piece has a banded appearance of more translucent and more opaque white material, in concentric rings out to a raised undulating warty edge on one side, with the other side raised straight up, showing the translucency of the material against a white background.
  • A closer detail view of the oval with concentric banding, the edges more bulbous and lumpy with botryoidal forms. The chalcedony is slightly translucent so you can see the dark matrix under half of it, the other half with a soft translucency through thicker chalcedony.
  • The large oval formation on the specimen fluorescing strong yellow-green under UV light in low lighting.
  • Another side of the piece, with a wide flat oval of chalcedony formed of concentric bands of even color, the pink tint hardly detectable.
  • Side-view of the piece, showing the two formations are back-to back, the part of the first one folded up against the back of the large oval piece, melding together with a fat lumpy rim. The centers of the concentric banding for the two formations are very near one another. The oval piece is curled a one edge.
  • Side-view of the specimen, the thick edges of the clam formation pouring over the side with swirling form and botryoidal growth. A natural-appearing fracture, lightly iron-stained, starts in the top of the rim and runs toward the center of the two chalcedony formations.
  • The reverse of the specimen, a light tan-gray rocky matrix with some small round pebble-like grains in it.
  • The piece on a measuring mat, measuring about two inches 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.

Pink chalcedony often forms shapes like a nest, cup, or knobby "ear" with raised curved rims of snaking 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 specimen is good-sized, with two large 'clamshells' of faint pink chalcedony with concentric banding, back-to-back and forming a raised edge. What this specimen lacks in color, it makes up for in form, with undulating thick edges and knobby botryoidal forms. Some opaque whitish layers form agate banding of white and translucent chalcedony, most apparent in the middle of the concentric banding. 

UV reactivity this material has an excellent UV reaction, most pieces glowing a strong green under 365nm UV light. This piece has a very good UV reaction, with the main chalcedony formations glowing a strong green. There is also a vein of chalcedony through the matrix that has an even more vivid reaction. No phosphorescence detected.
