Yes, they are the Eighteen Arhats.If they are purely soft white color, I mean Hetian jade, they are more precious. No one can tell the value without seeing the jade quality, caving skills, sizes of each figurines, when did you bought it and excatly how old are they. I can give your a reference according to the current price of white Hetian jade.1kg Hetian Jade raw material costs 2 million yuan, the top grade Hetian jade I mean. So, even if they are but top jade, jade price now is very hight. If they are items from the Qing Dynasty which is 2-3 hundreds years ago, wow, I can't tell the price then.
