Top quality round pearls with excellent luster (note Grade AAA). The tiny diamonds are much better quality than in other purchase options (note G-H/I-1 description), so they sparkle, and are the perfect touch. These are freshwater, not akoya, which makes them more affordable; yet they are perfectly round with very high iridescence - impossible to tell the difference in this pair of earrings. If you're looking for a high-grade classic pearl stud with diamond accent, don't hesitate on these.
