I have questioned the authenticity of the Ozzie site just because the prices are so low but many on this site say they are genuine. A few others that sell genuine Pandora are JewelFirst and UnforgettableMemories in the UK, although their stock seems to be diminished and pandorastore.be in Belgium. The Belgian store has quite a few retired charms in their Outlet store right now including the palm tree and coconut charm and the divine seaside Kiss with genuine blue topaz. Sometimes when you are on eBay trolling the charms check the sellers name to see if it is a brick and mortar jewelry store selling online. Their offerings can be considered genuine especially when they are selling high priced jewelry from other lines such as David Virtue, Lagos or David Yurman. In Canada there is a store in British Columbia called Charm Junction that also sells retired charms. I have bought quite a few from them. The only issues I have sometimes is that the prices become outrageously high the rarer the charm becomes so you have to be quick.
