There are many bracelets appearing on Ebay that are fakes, compared to a genuine article you can tell the quality from a mile away.
The best check is the hallmark that should be present on one of the links at the side of the thick barrel.
Check the seller's feed-back, if they regularly sell these bracelets then the chances are that if they are not a shop or business then the bracelet will be fake.
These bracelets are about £110.00 in good retail shops, so don't get fooled if you pay £40.00 for one that its a bargain/genuine item.
There are many purchasers out there that have won these bracelets at a good price, left positive feed-back, only to discover their purchase is a fake.
If in doubt take your bracelet to a good jeweller and get their opinion.
I hope this stops 1 person for being conned like I was.
