Lanper's "Blue"
Lanper is a very rare species in amber, and is recognized as the "king of amber" in the jewelry industry. Among the many amber varieties, Lanpo has become a new favorite of the collection because of its high collection value and soaring prices.
The reason why Lanpo is precious is that it is exceptionally fascinating because of its distinctive color. Generally, the formation of amber color is directly related to the minerals in the soil, except for the resin itself. Iron, manganese, copper, etc. can produce different colors of amber under long-term contact. The cause of most amber colors has a definite conclusion, and the cause of the formation of the blue color has not been unified.
Blueper formation conditions
The origin of Lanpo is known as the national treasure of the Dominican Republic in Central America. It comes from the leguminous plant resin 30 million years ago. Its special blue causes are widely discussed. It is widely recognized by the scientific community that the amber is heated by the volcanic lava flowing through the surface.
Lanper was originally a common amber in the formation. It was the high temperature of the Dominican volcano erupted thousands of years ago, causing pyrolysis of the buried amber in the formation, and the fluorescent substance produced during the pyrolysis process, the polycyclic aromatic molecule, was incorporated into the amber. Among them, this is the core of the formation of the mysterious color of the blue. It can be seen that the unique geological conditions of Dominica at the time can contribute to the formation of Lanpo, which is why it is only produced in the country.
The value of Lanpo
Dominica amber production accounts for only 1% of the world's production, and Lanper's annual production is less than 3% of amber production, so precious, combined with its beautiful optical effects, laid the blue bull's dominance in the amber world.
Different from general amber, only one or two color systems can be displayed. Lanper will display five or more colors such as blue, green, yellow, purple and brown as the light changes. Its deep and unique beauty makes it in the European and American markets. It is often used in high-end jewellery and art collections. It is the most popular "Smurf" gem in the European royal family.
There are different reasons for this.
The density of amber is very small, and it is easily transported by rivers and streams to the shoals for long distances. Then the diatom mud deposits are buried and gradually form sedimentary rocks. During the formation process, diatom plants buried in the same period can easily secrete oily substances. These vegetable oils will penetrate into the interior of amber, so a blue-like blue tone similar to that seen on coal tar is seen in amber. .
But the above can only explain that amber is blue, but it can't further explain why Lanper has other special properties, such as obvious fluorescence reaction concentrated on the surface, not even disappeared due to multiple polishing; why there are few internal features, Or light sees the internal features of false twins; why are bubbles and flow lines rarely seen and so on.
Another hypothesis is related to volcanic activity and major forest fires. Volcanic motion generally causes the earth's crust to sway or generate a strong earthquake, and the resulting local high pressure will cause the amber in the molten state to deform. Just as a crystal lattice defect can produce a color, the deformation can also cause a weak fluorescence inside the amber. The bubbles and moisture present inside the amber are also squeezed out due to deformation.
At the same time, the surrounding oil and other minerals are also melted and poured into liquid amber under the high temperature and pressure caused by volcanic eruptions. After the volcanic activity, the resin will be re-scented into amber. The resulting amber material becomes harder, more irregular, has more cracks and is more brittle, and the blue fluorescence is seen by peeling off the skin of the material.
Although the color causes of Lanpo still have differences in the scientific community, there are two points that can be affirmed: the blue color in Lanpo cannot be dyed, and it is impossible to rely on different substances like the blue sky we see. Refraction occurs in the middle and is caused by diffuse reflection on the surface of the material.
As for the final color cause of Lanpo, it is still necessary for research institutions and scientists to carry out more in-depth research in order to find sufficient evidence to finalize the conclusion.
