Description: This is an intricate white gold filigree ring dating to between the 1920's-40's. The die-struck mounting is in very good condition with the bottom of the shank reworked in a lower karat gold (+/- 12K). Set with a 19th century .64 carat Old-Mine Cut diamond (K color, I1 clarity). The I1 clarity rating is due to an included cloud of carbon on the edge of the stone. It is quite difficult to spot this with the naked eye. The small full-cut diamonds on either side add a bit more sparkle to the filagree decoration.
