Blue Amber, Indonesia
Blue amber comes from only a few localities – most notably the Dominican Republic; also Chiapas, Mexico, and Indonesia. It is so named because it reacts with ultraviolet light and fluoresces blue in sunlight, while it appears the normal golden-brown colour range of other amber in artificial light, or when sunlight passes through rather than against it. So far, all blue amber tested has been from the resin of the now extinct tree, Hymenaea protera (bean tree).
