📜 Key facts

AgeMiocene, about 20–15 million years old
Origin & sourcesDominican Republic (Cordillera Septentrional, near Santiago). Smaller amounts come from Mexico (Chiapas) and Indonesia.
CompositionFossil tree resin (from the extinct tree Hymenaea protera) containing fluorescent aromatic hydrocarbons

How it forms

Resin from ancient trees was buried and hardened over millions of years. In daylight it looks yellow-brown, but it shows a blue surface glow in sunlight and glows strongly blue under UV light, probably from aromatic compounds.

Mineral data: see Amber.

Dominican blue amber shows a blue sheen even in sunlight and glows intensely blue under longwave UV.

Reactions vary by locality and specimen; many specimens of a fluorescent species do not glow. Shortwave UV can burn skin and damage eyes. Wear UV-blocking glasses, and never look into any UV lamp. Sources: Wikipedia: Dominican amber. More UV-reactive stones →
