This is a very beautiful pearl. It's not just plain black, but has hints of green, gray, and a touch of red, creating a captivating play of colors depending on the viewing angle. Two small square diamonds are set on either side of the pearl, adding an elegant touch. At 11mm, it's a large size with volume and presence.
