I have a passion for collecting ,refinishing transforming , sewing,painting,photography & up-cycling.Pieces are either mine,my collectibles,altered pieces,estate pieces or flea market finds & for this reason will be sold as is.

It will be priced accordingly due to the fact it’s not marked sterling . One ring only this listing. Color is matte rusty red
