Platinum 950; 6.9 grams; Sold to me as size 6, hits at size 53 (just above 6.25 before 6.5) on my mandrel. Previously held an oval that was 8.5x7mm but if you review photos you'll see it was filled in to fit this stone from a previous, larger stone. It fits ten, 3.1mm round diamonds (1.28ctw in previous life). Some wear/distortion from stones being removed (see photos), priced accordingly. Will throw in previous blue oval center stone on request for free. Will take any additional pics requested. All sales final. $350 obo shipped within USA. *Edit 2/16; Ring is stamped "PT 950" "2.732" and "D 1.28" for original stones.
