Sterling Silver Prayer Box Necklace Charm Floral Trinket Keepsake Hinged Locket

Sterling Silver Prayer Box Necklace Charm Floral Trinket Keepsake Hinged Locket Great condition, cute little charm. I am not 100% positive if this is sterling silver or if it's just plated, as it's unmarked. I did polish it and it's not magnetic, and I found a very similar piece on Amazon that's labeled as silver and have included a photo. Please see photos for details and measurement
