This is an unusual Diamond engagement ring. It is a truly round stone in a setting which gives the illusion of a heart shaped stone. Very clever!
The ring has a 0.65CT "I" SI1 Diamond which faces up very white. It is flanked by @0.10CT TW accent round cut Diamonds which match very well. I did not notice a mark so the item has been acid tested and is guaranteed to be 14K. It is size 5 and weighs 2.3 grams. The Center stone is 5.54-5.56 mm by 3.46 mm.
The ring will come with an appraisal which sets the replacement price at $3100. A wonderful engagement ring or a fine ring to wear with others in a stack.
