Important et rare ambre bleu, Indonésie

Cet ambre possède la particularité de renfermer des particules microscopiques issues d'une combustion de son environnement direct lors de sa formation.  Il pourrait s'agir d'une éruption volcanique ou d'un incendie  qui se serait produit, il y a maintenant 20 millions d'années.

Ces particules ont la propriété de générer une réfraction de la lumière et l'ambre arbore alors cette couleur d'un bleu intense lorsqu'il est exposé aux rayons du soleil ou aux rayons ultra violet d'un dispositif spécifique.

There are 4 pieces. The bigger one is polished without traces. The two other blue amber : one is polished on just one face, the reverse is not ; the other one is totally not polished (raw state). The classic yellow amber is polished all over the surface. The colour is completely natural, not painting, no treatment, no nothing.This blue colour is due to the UV lamp. This amber is presented and sold in a showcase with UV lamp. Without UV lamp the colour is darker. The particularity of this amber is that we can see inside some microscopic particles of ash. All is purely natural. The four pieces are in perfect condition.
