VINTAGE DIAMOND ENGAGEMENT RING SET

From an estate sale comes this vintage genuine diamond engagement ring set crafted of solid 14 karat yellow gold.  The ring weighs 7.80 grams and is a finger size 5.  If you need another ring size, please contact me for sizing charges. Apparently, these were three separate rings and the owner decided to have them soldered together to make it one ring.  Total carat weight is approximately 0.25 ctw.  The center diamond is G/H color, SI clarity.  My best estimate as to the time period of this ring is 1960's-1970's.  The ring has a width of approximately 10mm.  The shanks are marked 14K and have other markings which I can not make out.  I have professionally polished and cleaned this item and it will ship in a gift box.
