This is a wonderful detailed vintage Conch Shell Charm perfect for a Charm Bracelet or use for a pendant on a necklace. Does not have a 925 stamp that I can see but it does have something stamped that I just can't make out. See Photo 3. I did however test this for silver and it tested positive. Weighs at 1.54g Please see photo for size. This is in wonderful vintage condition and has wonderful detail all the way around. Whether you collect shells or if you just love the seashore you will love this little work of art. Please contact me if you would like more than one charm and I can adjust the shipping price.
