💎 Description

In daylight, this Franklin specimen shows a dark, sparkling surface with a vivid iridescent sheen that flashes purple and blue across the face. Reddish-brown tones along the edges add warmth to the darker body.

Under UV, the piece reveals a completely different character. Chlorophane glows teal-green across much of the surface at both wavelengths, with the strongest response along the right side. Sphalerite adds contrasting color: abundant orange flecks and pink accents under shortwave, and pink spots under longwave. After either lamp is switched off, the chlorophane continues to glow teal-green for 2-3 seconds.

The orange and pink sphalerite scattered across the teal-green chlorophane gives this compact piece an unusual and colorful look under SW.
