Baltic Amber Teardrop Earrings

1. The oldest amber with arthropod inclusions comes from the Levant, from Lebanon and Jordan. This amber, roughly 125–135 million years old, is considered of high scientific value, providing evidence of some of the oldest sampled ecosystems.
2. Although there are several theories about the origin of Dominican blue amber, there is a great probability that it owes its existence to ingredients such as anthracene as a result of incomplete combustion due to forest fires among the extinct species Hymenaea protera trees about 25 to 40 million years ago.
3. The largest deposit in the world is west of Kalimingrad in Russia, in a layer of amber-containing clay about 30 meters below the surface.
4. Amber brings together Irelands leading material science researchers working across the disciplines of Physics, Chemistry, Bioengineering and Medicine.
5. These studies show that the blue variety reveals an intense fluorescence emission in the visible wavelength region, between 430 and 530 nm, with spectral features typical of aromatic hydrocarbons.
6. This effect is only possible in some specimens of Dominican amber category, in some Mexican ambers from Chiapas and some ambers from Indonesia.
