Fluorescent Trancas Geode with Helicites and Chalcedony F

This is a specimen that operates on multiple levels of wonder. A Fluorescent Trancas geode from Mexico, already prized for its vivid UV response, this piece goes further — hosting both helicites and chalcedony within a single formation. The helicites spiral outward in their characteristic gravity-defying fashion, branching in seemingly impossible directions with no regard for predictable crystal geometry. The chalcedony layers in smooth, translucent masses alongside them, its waxy luminosity a quiet counterpoint to the helicites' wild architecture. And under UV light, the entire piece transforms — glowing with vivid fluorescent color that reveals the hidden energy locked within the stone.

At nearly five inches across and just under a pound, this is a substantial geode with genuine display presence — a collector's piece that rewards examination from every angle and under every light source.

• Dimensions: 4.8" x 3.7" x 1.5"
• Weight: 0.88 lbs
• Material: Natural Fluorescent Trancas with Helicites and Chalcedony
• Notable Features: Rare helicite formations; chalcedony inclusions; glows under UV light

A piece like this sits at the intersection of geological rarity and natural artistry — the kind of specimen that serious collectors seek out and casual admirers simply cannot stop looking at. Whether displayed under natural light or illuminated with UV, it never looks the same twice.

As a natural specimen, helicite formation, chalcedony coverage, fluorescence intensity, and exact dimensions will vary slightly from piece to piece. UV light not included.
