18K Gold Filled Peach Trillion Cut Crystal Cocktail Ring

This is such a pretty ring! Trillion cut peach-ish crystal center stone. Crystal? Cubic Zirconia? It has loads of sparkle! There are two rows of clear crystals on either side of it. Notice how one row curves around the center stone and one is straight. These could be diamonds and worth a fortune, but I don't have a diamond tester 👎😆They do kinda have a genuine quality to them.. just saying. This is for real a very nice looking ring!
It is marked inside: 18KGF
My sizer says it's just under a size 8, and it does feel like it, as it feels snug on my size 8 pointer finger. Metal shows minor wear when zooming in when taking photos.
