• Blue Amber is the name given to the fossilized resin from the prehistoric leguminous tree Hymenaea Protera. Blue Amber is rare compared to the yellow/brown form of Amber, and its main source is from the Dominican Republic, although it has also been found on the Indonesian island of Sumatra. This form of Amber is so called due to the slight blue toned hue it exhibits in strong ultraviolet light.
• Under artificial light, the amber appears like ordinary amber, but under sunlight it has an intense fluorescent blue glow. When held against the sun it will appear like ordinary amber, and under ultraviolet light it will glow a bright milky-blue. Hardness: Dominican amber is the softest at - 1-2; Colors: Light Yellow To Dark Brown, Orange, Red, White; Greenish, Bluish Due To Fluorescence;
• Amber is a gemstone formed through the fossilization of tree resin. Amber resin is not the same as typical tree sap. It is sourced specifically from the Pinus succinifera tree. The fossilization of amber can be traced back to the Tertiary period, meaning that amber stones formed aproximately 50 million years ago. Since amber is formed from soft and sticky resin, amber often contains animal and plant inclusions; mostly mosquitoes and other insect species.
