| Margaret,
I'd recommend staying away from using grades such as AAA+ and Gem. This implies that a company using these grades, sells a sub-par AAA quality. It also creates confusion for the customer.
Even worse is when a company goes far beyond the "accepted" A to AAA scale by using a AAAA grade.
My recommendation would be to narrow your buying decision down to two dealers. Make sure they both have good, unconditional return policies with no restocking fees. Purchase the "identical" necklace from both dealers, and return the one you don't like. And since you're using a credit card, you don't even have to have the money in the bank to take this approach. |
