The Silver Jewelry Club: silverjewelryclub.com offers high-quality jewelry including silver rings, earrings, pendants and bracelets (most of them with genuine gemstones). It really is free, provided you pay the modest shipping charge of $5.99 or $6.99. This is not junk. There are great reviews here. It is true silver.
Giving away jewelry is SJC's way of introducing their products-they also sell their jewelry through wholesalers and stores.
