I am a jewelry and jade lover, and I go to Beijing to attend the international jewelry exhibition every year. A few days ago, the jewelry exhibition of the National Exhibition was much bigger than in previous years, and there were more merchants and stones, many of which were fresh. In my opinion, the Australian green treasure you mentioned should be foreign stones. I suggest that if you have the energy, you can go to Peking University, Dada or Wuhan Dada Testing Center for testing. These three institutions are recognized as authoritative institutions in China. If the name is decided by the merchant himself, it is meaningless. If the national inspection can name it Olubao, it is probably a new stone. Now the new stone has great potential. I hope to have a further understanding.
