It's really hard for you to get someone to look at a number for you. There is really nothing to say about what I bought on a trip. You bought too many Lantian jade bracelets on a trip, but they are not from lantian jade. Many of them are fake stone bracelets. Look at the picture specifically.

"lantian jade" is named after it was produced in Lantian Mountain, Xi City, Shaanxi Province. There are records of beautiful jade produced in Lantian in ancient books. "History of Han Geography" contains: "Meiyu is produced in Lantian, with a tiger in Houshan Temple and also in Qin Xiaogong." Later, there were records of Lantian's jade production in ancient books such as Biography of consorts in the Later Han Dynasty, Xijing Fu, Guangya, Notes on Water Mirrors and Yuanhe County Records. The modern mining lantian jade mine is located in Hongmensi Village, Yuchuan Town, Lantian County. The ore-bearing strata are Archean biotite schist and amphibole gneiss. Jade is fine-grained marble, mainly composed of calcite.

Look, the so-called lantian jade in modern times is actually marble.
