EllensburgBlue Agate is a blue agate found only in the foothills of the Cascade Mountains northwest of Ellensburg, Washington, USA. Although other blue agates are found elsew (for example, the Blue Lace and the Asian Blue Chalcedony), the Ellensburg Blue is unique in several respects, and an expert can distinguish the Ellensburg Blue from other more common forms of blue agate. Their unique chemical composition, with titanium and 42 other trace elements, is a result of the volcanic action in that region. In addition, with a Mohs scale rating of 7.5 to 8.3, Ellensburg Blue agates are somewhat harder than most agates, which are Mohs scale 7. Unlike many agates found in sedementary beds, Ellensburg Blues are found only in the cores of geodes in the glacial scatter fields of their range. Most geodes found in that area yield an inferior grey stone at their cores. Only a small proportion of these are blue, and an even smaller proportion are suitable for jewelry. Top quality Ellensburg Blue agates are sold by the carat for hundreds of dollars. The Ellensburg Blue is regarded by some accounts as a precious rather than a semiprecious stone, and the third rarest gemstone in the world.
