Hand-fabricated in silver over 15ct. rose gold, hence of British origin, this classic ultra-sparkler, dating from the-turn-of-the-last-century, dazzles with a coruscating constellation of 9 bright white old mine-cut diamonds, 8 of which orbit around a .47 carat center stone. The sizable crown measures 9/16 inch diameter, the sleek knife-edge ring shank is currently size 7 1/4. 2.07 carats total diamond weight. A beauty.
