You have some disposable cash and you are looking to buy a Diamond Rolex. EBay is a good place to find one. You have to be careful about certain things before you bid. Do the diamonds look real? Does the serial number match the type of watch? Once you check everything out about the watch, you have to look at the price.
The clarity of the diamonds is also a factor. Chances are that if everything checks out then the diamonds would be real. Some people might change the diamonds and sell the watch. As long as you are diligent enough to get the seller to say the diamonds are real, then there is a chance to get the right ones. If the seller lies about it, you have some legal recourse. Buying a Diamond Rolex on EBay is a big step. You can get a watch for a fraction of the original price.
