Does the trick for the price
I can see an obvious color change. Does the trick when grading or educating. Not sure its GIA standard but it works. Also , in the pics it shows two rows... one face up and one upside down. There is ONLY one row of stones. Not sure why they did that. Misleading !! I will try to come beck and attach a pic. Mine are at work.

Waste of time and money
The simulated stones were identical in color so it was useless for diamond color grading. Zero difference between what should be the "whitest" stone (D) and what should be the most "yellow" (N). The item came from China and cost $28 to return the $100 item to China. I think they just hope you don't want to pay the return shipping so they can keep your money. I should have known it was too good to be true as price was 1/3 of other resellers.
