This is a gorgeous deepest blue amber from a discovery in Sumatra, Indonesia. The amber weighs 6.5 oz and measures 3.25” by 3” by 2.4” … surprisingly light for its size! This is a raw piece and her sides show areas of a natural “rind” that is a series of brown and gold bubbles. She is opaque and you really need a bright light to see her true colors, displayed in glassy fashion. The blue arises from her origins … she was formed from the sap of the Hymenaea protera tree, the same tree that contributes the color to Dominican amber. Hymenaea protera is an extinct prehistoric leguminous tree, the probable ancestor of present-day Hymenaea species. Most neotropical ambers come from its fossilized resin, including the famous Dominican amber and now the Sumatran amber. This heritage is what gives the blue amber it’s famous blue color and lovely blue fluorescence. The Sumatran blue ambers are far bluer than the Dominican amber. The Dominican will show the blue fluorescence in sunlight whereas the Sumatran amber is deep blue to begin with and shows a notable somewhat turquoise-blue when ultraviolet light hits it. The Sumatran amber is transparent only in thin areas and may reveal golden to red tones. Now, for the really special part … with a black light (UV), that blue becomes kind of an ocean blue! And the little dots you see are tiny bubbles! She is full of surprises … but no bugs that I can see! Apologies for the photography … her contours are so irregular that it’s hard to find a good focus! Please note that the pink is not fluorescent, but rather a reflection from the UV flashlight that I use. Amber is a miracle of nature!
