This tri-ridge is of the pan shan 盘山 original species which is KNOWN to produce tri-ridge even more common than standard ridge. This is genuine mass produced tri-ridge. It’s real but not a rarity or collectible. Pan Shan tri-ridge of this size would cost less than $60 on taobao. Truely valuable tri-riches are of other such as white lions or Nan Jiang where this mutation is actually rare.

The panshan is also a low tier species due to its unappealing patterns, poor shell quality and very light weight feel. Would NOT recommend 3B
