A Mikimoto diamond and baby pearl ring. Size: Size 9 Ring width: Approximately 1.8mm Pearl size: Approximately 3.0mm to 3.5mm Type of pearl: Akoya pearl Hallmark: Mikimoto mark, K18 Weight: Approximately 2.7g Accessories: None Baby pearls are considered rarer the smaller their diameter, and Mikimoto no longer carries 3.0mm pearls, making this a very valuable piece. The pearls have a white to white-pink color, with beautiful pink iridescence. The luster and nacre are both good, and I believe these are high-quality pearls without any noticeable blemishes or surface imperfections. The diamonds are nearly colorless and transparent, with good brilliance. The ring has been polished for sale, so it is in excellent condition with no particular issues. The case in the images is for another ring and is not included. Material... Gold Ring Size... Size 9 Stone... Pearl Stone... Diamond
