I always come to The Fifth Collection when I'm looking for a designer luxury piece of jewelry! They have a great selection of items, the prices are really fair, they always have a description, you can zoom in on the item & if you still have any questions on the sizing, you're always able to start a "chat" & either they'll answer you pretty quickly or they'll email you back with the answers! And, Free Shipping & they ship quite quickly! So, the purchase that I made was the Hermes Dog Whistle Necklace, it was gorgeous, came as described in the description & pictures! When I inquired about the length, I was emailed the next day with the information! I never worry about the authenticity of their items! My only issue, is that they're not able to send any exotic skin items to the US because of not having the CITES paperwork. But, that's a legal issue, can't get around that. Thank you for being such a great company!!!
