Yes! I recognized your name too and wondered if it was the Carolina Bucci bracelets we met over. xD I still have mine, but don't wear it anymore! I should!! Even that bracelet I got secondhand for much cheaper than retail.
eBay has a pretty good return policy that really favors the buyer, so I always feel comfortable buying from them. I've purchased a lot of expensive jewelry over the internet, from overseas, and haven't yet had a problem. The biggest scare was once the package got lost in the mail, but eBay refunded both me and the seller the amount (because it went through eBay's global shipping program, it was their problem), and then the item still turned up many weeks later! I told the seller, but they'd already gotten paid, and I told the shipping program too, but they didn't care, so I ended up with free jewelry.
I think if you're careful and look through the seller's feedback + photos carefully, you can find authentic deals. I use picclick to search through lots of eBay listings, it's a pretty good tool!
I still have my carolina bucci bracelet but cant wear it as so much of the thread broke and unravelled . Its still my favourite bracelet and i keep meaning to see if it can be repaired.
I think i will have a look on ebay then !
Im no expert at spotting fakes so will need to find out how to have things authenticated
