This is my first pearl purchase. I found these at a very reputable consignment store. They had no history on them from the owner. They labeled them as Freshwater, 16”, 8.6mm. H 925 China on side of push clasp. Says Base metal bottom on bottom of clasp. Gritty when rubbed together. A couple pearls have a slight dimple. Paid $147 for. I would love any information on type of freshwater pearl, quality, value, and brand if identifiable. Hoping I did okay with this purchase!
