The little delicate pearls average 3.25mm, are round and matched well in size. At the center is a teardrop 11mm x 6mm, 14K Pearl pendant. Pearls have a very nice luster with very good reflection. There are some minute surface imperfections with magnification here and there due to their natural formation. Nothing noticeable when worn. I don't have much information on this necklace. I assume they are cultured freshwater pearls since they are button shaped. Pre-owned, estate necklace. When I was viewing them with a strong loupe I can see they need a light cleaning and there is a knot near the clasp that is darkened. Being sold as is and I've priced accordingly. The spring ring clasp is stamped 14K and has a tag attached with the maker's mark I.P.S. Tag is also stamped 14k with another mark of an H inside of an oval circle. Necklace weighs 7.3 grams and measures 17.5" long. Very feminine, elegant, timeless pearl necklace. Please view my other listings. I am always happy to combine shipping on multiple items.
