I am listing this at my sister's request. These are approximately 11.5mm, perfectly round pearls. They are neither too dark nor too light, with excellent luster and a very good sheen. I selected pearls that include the most popular peacock green color. Some minor natural blemishes are visible, but they are hardly noticeable when worn, which is typical for black lip pearls. They have been used a few times and are in like-new condition. They have been cleaned with an ultrasonic cleaner. The findings are K14WG with silicone backs. These are perfect for both casual outings and formal occasions. The weight is approximately 4.8mm per pair.
