Amber is a fossil resin that was produced by pine trees that grew in Northern Europe over 45 million years ago. There are several types of natural amber, from wax white, bright yellow to dark yellow, brownish-orange, and in very rare cases, red or blue. It it mostly opaque, due to the effects of the sun, and a small quantity is clear (transparent as glass) to almost clear. A small selection of fine amber jewelry can be found here.
