Maybe puzzle rings?
They're made out of 4-6 bands of silver that are technically separate but interconnected and not welded together.
And they're cheap compared to a lot of other jewellery... readily available at your local silver kiosk at the mall...
Or, depending on how your family feels about necklaces (a lot of people don't like them), you could get ones with a matching pendant that you all like.
