Can you be more specific to what kind of jewelry and coupon are you looking for? You can try jewelery from Zaful and Adrift. I know some places where you can get coupons and vouchers for discounts. See couponscod.com they have great deals. you may also find something interesting there. You can also get good deals from Ambersceats. They have coupons on BandGood too. I heard they have goo collection of jewelry.
