Hi, my daughter has a ring that she has been trying to identify on the net but can't find anything that matches the makers mark.
Can anybody help?

I need to know where she got the ring or rather how. I found an LU and matched the top mark, but before I say anything, I need to know more please. If I am correct that could be a very old ring. But I am tired, lost the info when I didn't write it down and need to go take medicineand get some sleep.

My daughter should have search a little more before asking me to post. This looks like the LIU hallmark and the art style is the same. I would be interrested to know what the characters mean since they are different than those shown on the website. I will wait a couple more days before marking this post solved in hopes of a translation.
