“Yemingzhu” mainly refers to minerals and rocks with “phosphorescence” (c'est, the phenomenon that still glows after turning off the light source). Only the “fluorescence phenomenon” can not be called Ye Mingzhu.
Yemingzhu has ancient names such as “Yeguangbi” et “Mingyuezhu”. During the Spring and Autumn Period and the Warring States Period, there were night pearls such as “Xuan Li”, “Chang Ji”, et “Suihou Zhu”, which were known as “famous artifacts in the world”. The ancient night pearl is recorded in official history, barnyard history, novels, and poetry. Although there has been no archaeological excavation of Ye Mingzhu so far, it does exist, but no one has seen what it is like in ancient times. He also pointed out: The ancient night pearl is an important part of Chinese jade culture and has become a kind of night pearl culture. Due to the underdeveloped science and technology in ancient times, it is impossible to correctly understand the reason why Ye Mingzhu shines, so Ye Mingzhu is covered with a layer of mystery.
Asked from 2001 à 2002, many “perles nocturnes” were found in our country. According to modern technical tests, the reason for the phosphorescence of the fluorite “night pearl” is due to the “luminescence center” of the mineral in the crystallization process.
my country’s fluorite mines are rich in reserves and widely distributed, but among these fluorite resources, only a few of them can be made into “perles nocturnes”.
Specifically, only those fluorites with a “phosphorescent effect” can make “perles nocturnes”.
When evaluating the quality of “Yemingzhu”, not only the intensity of its luminescence at night (or in a dark environment) must be measured, but also the length of the luminescence decay time. The longer the luminescence time, plus la valeur est élevée.
How do ordinary people recognize whether fluorite minerals (or fluorite balls) have a “phosphorescent effect”? D'abord, use a currency detector lamp (fluorescent lamp) to illuminate the fluorite to be tested. Par exemple, it emits light (purple or green) when illuminated, and the light source is turned off and still emits light. C'est le “phosphorescence effect”, c'est, like a luminous watch, it also emits light without light. It is the “Night Pearl”. Inversement, when the light source is turned off, it will no longer emit light, which is the “fluorescence effect”, c'est, like the display phenomenon of “100” in a banknote, it is not a “night pearl”.
Such gems are usually collected separately and rarely sold as jewelry.
