(Due to a move/I am unable to locate the appraisal but I do have a photo as shown used for insurance purposes for your review) 14kt Wht Gold. C&C Rose Cut stone/ David Klass setting. Huge Charles and Colvard Forever Brilliant Moissanite Rose Cut Ring with Side genuine (Earth Mined) French cut Diamonds. I believe this is a 3ctw. I was told that the Rose Cut has been discontinued and is rare in this large size. Looks even larger as you can see in the photos because rose cut stones are wider versus deep in my opinion. Please read up on this cut so that you can be sure it is the "look" that you are seeking. It is a very romantic piece. Moissanite tests as diamond with a diamond tester (see photo) but is not a diamond. Feel free to message me with questions. I am very responsive. Reasonable offers considered. Here is more info on the ring. Charles and Colvard Forever Brilliant Moissanite Rose Cut stone set into a Ring with Side French cut Diamonds set by David Klass. I was told C&C used the very white rough used to create this stone....this is a beautiful vintage inspired moissanite rose cut stone. Flashes are large and bold. It is a vintage cut and has a different kind of sparkle than what we usually see in a round cut diamond ring, for example. This is set with two h 2mm v. s french cut genuine diamonds on each side to add to the vintage flare of the ring. (There are four 2 mm french cuts total). Ring size 5 sizeable within reason. Low set open under-gallery , the flashes are so much prettier this way. I was told that they have discontinued the rose cut.

This ring was designed by myself and set by David Klass. He took my drawing/created the CAD (shown in photos) and created this HEAVY ring. The 14kt white gold is of his own formula where the alloy + gold mix never requires replating. It is the color it is…and has been, since I received it. I am showing the appraisal that was included - however, since my move I am unable to locate it. Thankfully, I had photographed it for insurance purposes. This is a size 5/Euroshank. Remember that Moissanite is not heavy (like CZ is) in actual physical weight - so that gram weight is mostly gold weight. As such, I have it listed a bit over melt. This stone is not C&C and I probably should have allowed for more light to enter from the setting. But I really wanted a chonky ring. That said, this shines in the sun and I very much enjoyed it. It doesn’t suite my lifestyle these days and never really was worn much. If you have any interest, let me know. Otherwise I may turn it into my gold guy. Please write with any questions.
