History of Ellensburg Blue Agate

A Gemstone’s Tale Begins

The story of the Ellensburg Blue Agate is as captivating as the gemstone itself. It’s a tale that begins with a discovery by Austin Miers, the first mayor of Ellensburg, back in 1905. But the gemstone’s history stretches back even further, to a time when it was treasured by the Native American tribes of the region.

Native American Legacy

The Kittitas Indians were the first to uncover the beauty of these hidden gems. The Ellensburg Blue Agate was so highly valued that only the tribal chiefs were permitted to wear it. This tradition imbued the gemstone with a sense of prestige and exclusivity that still resonates today.

The Rise to Prominence

The Ellensburg Blue Agate began to draw wider attention around the 1920s. Its unique beauty and rarity quickly made it a favorite among gem enthusiasts and jewelers alike.

J.N.O. Thompson: The Jeweler Who Loved Blues

One of the key figures in popularizing the Ellensburg Blue Agate was J.N.O. Thompson. A jeweler who had a store in Ellensburg from 1913 to the 1940s, Thompson recognized the gemstone’s potential and played a significant role in bringing it to the public’s attention.


Tiffany & Co: The Ellensburg Blue Goes Global

The allure of the Ellensburg Blue Agate wasn’t confined to Washington State. Even the renowned New York jeweler Tiffany & Co. was captivated by the gemstone’s unique charm. In the late 1920s, Tiffany & Co. began using the gem in some of its jewelry, introducing the Ellensburg Blue Agate to a global audience and further enhancing its reputation.

A State Gem in the Making

The Ellensburg Blue Agate’s unique beauty and connection to Washington State led to a proposal to make it the state’s official gem. Although the bill proposing this missed a deadline and stalled, the nomination itself is a testament to the gemstone’s significance to the region.

The Challenge of Scarcity

By around the 1940s, the most productive agate beds were depleted. The surge of interest in the gemstone, fueled by “rock days” in the 1970s, led to a frenzy of hunting. This high traffic made the hunt for the Ellensburg Blue Agate even more challenging, adding to its mystique and desirability.

Formation and Characteristics of Ellensburg Blue Agate

The Ellensburg Blue Agate is more than just a pretty gemstone. It’s a testament to the wonders of nature and the passage of time. Let’s take a closer look at how this gemstone is formed and what makes it so unique.

A Geological Marvel

The formation of the Ellensburg Blue Agate is a tale of geological processes and millions of years. It’s a story that begins deep within the earth, in the heart of the Teanaway Basalt.


The Role of Teanaway Basalt

The Teanaway Basalt is a 47-million-year-old rock formation that plays a crucial role in the creation of the Ellensburg Blue Agate. This basalt is believed to be the birthplace of these gemstones, providing the perfect conditions for their formation.

The Formation Process

So, how does a chunk of basalt turn into a beautiful blue gemstone? It all comes down to fluid pressurization and mineralization. When fluid pressurizes deep in the earth, it can crack a solid chunk of basalt. This fluid, dense with minerals, then flows up the crack, mineralizing and growing out from the walls and into the middle of the crack. Over time, these mineralized veins transform into agate.

The Beauty of Blue

One of the most striking features of the Ellensburg Blue Agate is, of course, its color. But what gives this gemstone its unique blue hue?

The Science of Color

The blue color of the Ellensburg Blue Agate is thought to be due to refracted light from tiny particles within the stone. This is similar to why the sky appears blue. It’s a phenomenon known as Rayleigh scattering, where shorter wavelengths of light (like blue) are scattered more than longer wavelengths (like red). This scattering of light gives the Ellensburg Blue Agate its stunning blue color.

A Spectrum of Shades

Not all Ellensburg Blue Agates are the same color. In fact, they come in a variety of blue shades, adding to their allure.

From Sky Blue to Royal Blue

The color of an Ellensburg Blue Agate can range from a light sky blue to a deep royal blue. The most prized are those with a vibrant cornflower blue color. This variety of shades means that each Ellensburg Blue Agate is unique, adding to their appeal.


More Than Just Color

While the color of the Ellensburg Blue Agate is undoubtedly its most striking feature, there’s more to this gemstone than meets the eye.

Unique Markings

Each Ellensburg Blue Agate is marked with unique patterns. These can include cloudy images, streaks, and circular bands. These markings add character to each stone, making each one a unique piece of natural art.

Hard as a Rock

The Ellensburg Blue Agate isn’t just beautiful; it’s also incredibly hard. On the MOHs scale of hardness, which ranges from 1 (softest) to 10 (hardest), a Blue Agate scores a 7.5 or higher. This hardness is due to its mineral structure and contributes to its durability.
