My sons have been collecting and polishing stones for a little while now. Some of them are so pretty they thought theyd make jewellery for aunts/granny etc but I dont know where to get them from. Ive found my way to lots of jewellery "findings" sellers but no one seems to sell something that would "grab" the top of the stone (with or with our glue) yet have a hoop suitable to thread a chain through. Can anyone point me in the right direction please?
