Prior to her death 35 years ago, my mom always insisted that this was an early David Yurman ring. It doesn't fit me, so I have left it sitting in a safe all this time. I have never seen anything like it and have googled the heck out of it. It has a mark that looks like D.Y. 78 K18 950 (or D.V.78). it is beautifully crafted, weighs about 10.2 grams. Any thoughts?
