This is an K18 turtle locket necklace. The shell opens. There are three melee diamonds set on each of the feet, and high-quality diamonds are set. The necklace has been used very little, so I think it's in beautiful condition. Marking: K18 Diamond: 0.05 carat The chain is a through-adjuster type, and the length can be adjusted. Maximum length: approximately 45 cm Weight excluding stones: approximately 2.2 grams The stones to be exchanged are extras. The opal and blue stone are tanzanite, and the diamond-like stone is zirconia, which were removed from a ring, so they have some scratches. Please feel free to exchange them and enjoy them if you like.
