This webmaster states this: In case you're wondering, the rule regarding the posting of other jewelry information websites is in place because a great number of websites out there (in fact, the vast majority) contain advice and suggestions that, while labeled as "unbiased information", are actually designed to make you purchase from specific vendors that then kick back money to the information website (ie hence "biased"!). I believe that to be a disservice to consumers, and don't want Diamond.info to have any part in sending unknowing consumers to those websites. The only exceptions I will consider are links/references to organizations such as GIA and AGS that are 1) well-known and respected in the jewelry trade, and 2) existed prior to 1995. but yet on his homepage he has a search function that allows you to search for an online retailer which "kicks" money back to him. Read my reply on his thread for a better idea. http://www.diamond.info/forum/index.php?showtopic=2682
