These rings are made of .925 sterling silver. I am new to silverwork, so please give me grace with sizing & my welding! Nonetheless, these rings are beautiful, simple, dainty stackers. They can be daily wearers, as they’re super comfortable! If you are purchasing 3 or more, check out my other listings for a set of 3, for a discount! These rings are handmade to order, so please allow 1-2 weeks before your order is shipped.
