I've bought jewellery from Rare Lion and would highly recommend it. They sell jewellery at pretty competitive and reasonable prices. In fact, I've actually got my first necklace for my girlfriend from Rare Lion ;)
Best Antique Store to Buy Jewelry for Your Girlfriend Phoenix 2011 - Rare Lion Antiques & Jewelry
As pop star Neil Sedaka stated in his 1962 hit, breaking up is hard to do. Especially when there are so many ways to win your way back into the affections of your paramour. There are flowers, expensive gifts, heartfelt apologies, and good old-fashioned begging. If you're hoping that jewelry will do the trick, definitely go talk to Michelle Francis over at Rare Lion in Tempe. The antique shop owner has a particular knack for helping clueless Romeos pick out the perfect pendant or necklace as a making-up gift (or perhaps a birthday or Christmas present as well). Inside a pair of glass cases, Francis keeps a vast selection of bangles, baubles, and bracelets, all of which are of the vintage or antique variety. State what your gal's tastes are, and she'll use her sixth sense to figure out what her heart desires most, like maybe a cute pair of marcasite earrings. If things go your way, bub, she also stocks a variety of gorgeous rings that might be aces when popping the question.
