Ellensburg Blue Agate is the 3rd rarest gem stone in the world*. Presently only found in the NW corner the lower Kittitas Valley, near Ellensburg, Washington state and in Israel. In Ellensburg it was deposited by glacial movements so the true origin is unknown at this time.
Color of the E. Blue ranges from the light, sky blue thru a cornflower blue to an almost purple royal blue. Clouds, streaks, or bands may occur in the stone and graduates from nearly opaque to transparent. The hardness of E. Blue on the MOHS scale tests out at from 7.5 to 8.3 or harder on the scale.
Added my own private collection, photos at bottom of page!
I receive dozens of emails asking about appraising the blue and where to find it, and often I can't answer them because of my workload. Besides I can't tell you where I went I would have to show you....but here is the information on the experts in the field, No matter where you live they will appraise it for you.
