Yes, it's that fabulous. Stunning. Arresting.
With 3.78 carats of old European cut diamonds, bead set into an 18K white gold setting that is long on filigree as well as the WOW factor. And it's just long. The stones are G-H in color and vary in clarity from VS1 to SI1.
Wear it with confidence. Yes, it takes up a lot of your finger (but its design still allows your finger to bend. And it's surprisingly comfy.) North-to-south, you're looking at at a hair under 2 inches. East-to-west, about one inch at its widest, tapering down to 1/2 inch at either end. It weighs 7.3 pennyweights.
It measures a size 7, but the dome shaped on the interior will fit a finger that is 7 1/4 to 7 1/2. The shank was replaced at some point. It is stamped 18K.
