Natural Blue Amber From Indonesia 36.6ct Polished

A polished Indonesian blue amber piece with a beautifully rounded profile. In ordinary light it shows a warm caramel-brown body with a striking area of chalky white natural matrix still attached, creating exceptional contrast and textural interest between the smooth amber and the raw inclusion. Under 365nm UV or in direct sunlight the amber transforms to a vivid cobalt blue, the full extent of the effect playing across the surface and framing the matrix area in glowing color.

Indonesian blue amber from Sumatra is among the most coveted amber varieties worldwide. The dramatic blue optical effect is caused by naturally occurring fluorescent compounds locked into the ancient resin during fossilization, and it is entirely natural. No treatments have been applied. An excellent specimen for collectors or anyone fascinated by amber's rarer optical phenomena.
