I bought this for my teenage daughter. My friend who lives in China (Hi, Helmut!) told me the symbol was called a "Kang" and means "Health".  It really is stunning.

Pay attention to the photos, though. The side view clearly shows that the Jade is not inlaid, and I thought it was.  This is my fault since the pictures are clear, but it means that the silver Kang symbol is glued on top of the stone.  I am not sure I would have purchased this had I realized that at the time. The glue does seep out just a teeny tiny bit.  I noticed this yet my daughter, who now is wearing the ring, has not noticed this.  It's really just a small amount and it's milky colored so it almost matches the jade itself (yes, I know the jade is green-- but it still matches).  It makes it look as if the stone might have an imperfection on it keeping it from being perfectly flat.

All in all, I'm happy enough and my daughter is happy with it. Size was accurate.
