I've had this ring tucked aside for a while, but wasn't able to get far on actual origin of the hallmarks. I'm fine with American and European marks, but far eastern jewelry is usually well beyond me.
Face of the ring with passing dragons. The eyes test as diamonds, with turquoise set between them and red and slightly purple colored stones in the mouths which I can't identify.
Underside/construction. fairly heavily done for the size, weighs in at 24 grams.
And the all-important marks. Whether it's Korean, Chinese, Japanese etc I have no idea. Thanks in advance!
