I don't know what information you want to know about Lanpo, so I sorted out the related introduction of Lanpo from Chen Fu amber: Lanpo was originally ordinary amber in the stratum, and the high temperature caused by the eruption of Dominican volcano thousands of years ago pyrolyzed amber buried in the stratum, and the fluorescent substance-polycyclic aromatic hydrocarbons molecules produced during pyrolysis merged into amber, which is the core of the formation of Lanpo's mysterious color. It can be seen that the unique geological conditions in Dominica at that time contributed to the formation of Lanpo, which is why it was only produced in that country. Youlan Pearl (Sky Blue) is pale yellow and pure under natural light on a white background. When changing the angle, it will feel a slight blue reaction with naked eyes, a strong sky blue will appear under dark background and natural light, and a strong blue fluorescence will appear under purple light. Attach a picture. Lamper is beautiful in the light. Hope to adopt.
