14k Rose Gold Oval 1.37 Ct Tw 7x5mm Morganite Stud Earrings. The natural morganites are clean and have great color for their size. The color of the morganite plays wonderfully with the rose gold metal.  We bought a large parcel of these natural morganites a few years ago. They are hallmarked 14k on the ear posts and ear backs. We set the earrings.
