I created Blue Agates in 2001 (see pic of original site below) to educate the public on this rare beauty and make them aware that most of what is sold on eBay and other sites, is NOT Ellensburg Blue. 

Needless to say, there are now numerous sources selling Ellensburg Blue; however, the vast majority of what is pictured and sold online, while blue, is NOT Ellensburg Blue agate.

As the saying goes, Caveat Emptor - Buyer Beware!
