Sumatra Blue Amber (Sinamar Fm., ~30 Ma)
Palm-sized piece roughly 80g in weight. There is a very thin layer of coal on the top and bottom of the piece, making it a good example of a seam-type formation. It's blue coloration is purely surface fluorescence, initiated in this case by a 140 lumen LED light; this fluorescence (especially under a non-LW UV light) is caused by the presence of an exceptionally high concentration of various hydrocarbons contained within the amber.
