People living in Dominican Republic are very religious and superstitious people, who, for centuries have been using blue amber to guard themselves from "bad eye" and other supernatural events.
Chinese medicine also uses amber extensively, as a remedy for epilepsy, amnesia and urinary system diseases. Since ancient times, Chinese have called this organic gem "hu po" which means the courage or spirit of the tiger. They believed that amber transforms from the tears of a tiger as it breathes its last breath.
Of course the biggest mystery is the "glow" of the stone under the sunlight. Some liquid hydrocarbon mixtures have similar glow under the sunlight. The reason behind it is "perilene", molecules of which consume photons of electromagnetic oscillations, re-transmitting the energy in diapason of a lower frequencies. In short, perilene consumes UV and allows us to see it in the "blue glow".
