Multi Colored Fluorescent Opal & Chalcedony With Phosphorescent Matrix For Sale

This 270g specimen displays a highly variable fluorescent response under ultraviolet light, with distinct zones of blue, green, and warm tones visible under 365nm (longwave UV). The fluorescence is uneven and layered, highlighting internal structure and mineral variation across the piece.

Under shortwave UV (254nm), response is an electric green, producing a deeper, more concentrated glow.

This piece also exhibits considerable phosphorescence, continuing to emit light after the UV source is removed—primarily from the matrix and select chalcedony-rich zones.

Material consists of natural chalcedony and opalized silica within a mineralized matrix, with fluorescence and phosphorescence driven by trace activators in the host material.

Key Features:

• Multicolor fluorescence (blue, green, purple, yellow, orange)

• Reactive under both 365nm and 254nm UV

• Visible phosphorescence after UV exposure

• Natural, unaltered specimen (no dyes or treatments)

• Sculptural form with internal cavities and layered structure

Display Notes:

Best viewed in a dark environment under UV light. Fluorescence and phosphorescence are most apparent when light penetrates into the structure and cavities.
