Description:
Natural UV-active Indonesian Copal — a raw, fossilized tree resin that fluoresces under UV light. This specimen glows multi colors under shortwave or longwave UV, making it a great addition to any fluorescent mineral or fossil resin collection.
Features of UV-Active Indonesian Copal:
Color palette: Honey-yellow to golden-orange in daylight. Often translucent or semi-translucent with surface pits, fractures, or flow textures.
UV fluorescence:
Glows bright blue-white or greenish under UV light
Reacts to both longwave and shortwave UV (LW/SW), though intensity varies
Fluorescence helps distinguish real resin from plastic imitations
Hardness: ~1.5–2.5 (softer than true amber)
Location: Sourced from Indonesia, one of the major modern sources of copal resin.
Formation:
Copal forms from the hardened sap of ancient tropical trees, typically less than 1 million years old. Though younger than Baltic amber
