Purchased from someone who cultivates South Sea pearls. I was instantly captivated by the silver-gray color, luster, shine, and quality, and decided to buy it immediately. Please refer to photo 4.5 for the size. I was told by the representative that the size is 9-9.5mm. Clasp: K14 WG with sapphire, ¥50,000 Pearls: Retail price ¥2,000,000 (When I visited the Ginza Mikimoto store, I was shown various similar items, most of which were priced around ¥3,000,000) Thank you for looking. I have other items available, so please take a look if you'd like. #PearlLavieenRose
