Sterling silver .78 ct natural diamond ring!

This is a REAL natural mined diamond ring. There is nothing wrong with it, I just don't wear it. The ring was appraised at $800 and I paid about $300. Although I have an image of the certificate it came with, I don't seem to have the printed version any more. DETAILS: Diamond Color: I Metal Purity: 925 Clarity: I1 Main Stone Shape: Round pave diamonds Sizable: Yes Ring Size: 7 Style: Cocktail Total Carat Weight (TCW): .78
