This crescent has the most beautiful old cushion cuts. They have excellent optics and throw fire like crazy. Go check out the video on my Instagram grid to see it move! It features 2 carats total of natural antique diamonds set in 14k yellow gold. I estimate them at J/SI1.
the opening between the top of the tips is 1/2 inch. There is a small loop near the pin catch to accommodate a bale.
