Reposhing this item I purchased from @the_allisonian. Loved it, but ready to rotate for something new. Questions? Leave a comment below! Size 7.75 Marked 10K BISON I cannot find much info on the makers mark Tiffany/PRINCESS set 19 point 1.2-1.4mm (approx measurement With caliper!) round prong set GENUINE DIAMOND antique engagement ring! Scrolled band halfway on each side Weight is 3.97 grams 11.5mm square setting (princess/tiffany style from what I can find?) I found only 1 similar but the one I found is round or "popcorn style setting" but it has 19 round diamonds approximately the same size. It is listed as .20CTW at 599.99 This one is much more beautiful and has much more detail but is most likely the closest in carat size and age. This is a mix of 10kt yellow and white gold. White gold on the front plate, but the prongs are yellow gold White gold on the 2 sides of the ring that meet the band and yellow gold in the gallery with a unique Y inside of a square design Band is in excellent condition considering age Could use a reshaping if it bothers you, but it is not anything noticeable when wearing All stones are secure and in tact
