Ellensburg Blue Agate

Over 50 samples of Ellensburg Blue Agate are featured in the ongoing Rock and Mineral display, which is the largest collection held by a museum. These beautiful stones range in size, style, and vary from being raw to polished.

The first record of Ellensburg Blue Agates was in March 1905 when Austin Mires, Ellensburg’s first mayor, found a set of stones and sent them to jewelers in Seattle to be set into rings for his wife – and over 100 years later, the beautiful stones continue to fascinate seekers from all across the world.
