A study of the origins of the ambers which exhibit blue sheen concluded that the Sumatran and Dominican blue amber resins were produced by the extinct tree species Hymenaea Protera which lived 20 to 40 million years ago. Another of the unique qualities of this material is an aromatic fragrance when it is worked or exposed to flame. Unlike Baltic amber which may often contain bits of bark, trapped air bubbles, and sometimes insects, Sumatran amber is relatively less included but features dark color areas within its reddish-cognac body that resemble leopard spots. However, what is more distinct between the two is according to the GIA study, the blue color exhibited by the Sumatran Amber is the result of surface fluorescence stimulated by UV light. The UV is completely absorbed and does not penetrate or pass thru the amber as it does in crystalline stones like color change garnets, alexandrites and other gems. This phenomenon in which color changes with the wave length of light is called the Usambara Effect. The Usambara Effect exhibited by Sumatran amber is entirely superficial. This phenomenon is not observed in Baltic amber. Sumatran amber is not heated, clarified, or treated, and is completely natural.
