Comparison stones brown not yellow.

[diamondliz]

I ordered a new set of Gemoro comparison stones from an authorized retailer in the 1 carat size. When I went to use them the I-J-K comparison stones were brown and not yellow. I returned them thinking they were defective. When I got the new set back it was exactly the same. When I called Gemoro about this I got a supervisor who told me the manufacturer had made a mistake on the current batch and that is all they had. I am wondering where I can get a set of comparison stones that are not made by Gemoro?
