There’s something magnetic about holding an Oregon Sunstone in your hand — a piece of ancient fire born from lava and time. Long before it ever became the center stone of an engagement ring or part of a handcrafted heirloom, this gem carried a story shaped by volcanoes, Indigenous trade routes, frontier ambition, and modern small-scale mining in the American West.
Understanding that history adds another layer of meaning to the Oregon sunstone jewelry we create today.
Ancient Fire Beneath the High Desert
Oregon Sunstone formed between 13 and 17 million years ago during massive volcanic eruptions in what is now southeastern Oregon. Lava flows across the high desert slowly cooled, forming crystals of labradorite feldspar. What makes Oregon material so distinctive is the presence of native copper inclusions within the crystal structure. Those copper platelets create the shimmering schiller effect — flashes of gold, red, green, and champagne that seem to glow from within.

Unlike most sunstone deposits found elsewhere in the world, Oregon’s stones can display true reds and greens due to this copper content. If you’ve ever wondered what makes these gems so different, we explore that more deeply in our guide to what makes Oregon Sunstone unique.
Indigenous Discovery and Trade
Long before commercial mining began, Northern Paiute and other Indigenous peoples of the region recognized the stone’s beauty. Sunstones were gathered from the surface in the high desert and traded along established routes throughout the West. Archaeological evidence shows the material traveled far beyond Oregon, valued not only for adornment but for ceremonial use.

The gem’s connection to place runs deep. It was never just a mineral in the soil — it was part of the land’s cultural story.
Early Mining Efforts in the American West
By the late 1800s, prospectors and ranchers in the Plush area began noticing glittering crystals scattered across Rabbit Basin. The discovery caught the attention of the famed New York jewelry house Tiffany & Co., which purchased mining claims in the early 20th century. They briefly marketed the stones as “Plush Diamonds,” recognizing their brilliance and rarity.
However, southeastern Oregon’s remote terrain made large-scale mining difficult. Harsh weather, limited infrastructure, and challenging logistics ultimately caused early commercial ventures to fade.
It wasn’t until the 1970s and 1980s that renewed interest — driven by independent miners and rockhounds — brought Oregon Sunstone back into focus. A major discovery at the Ponderosa deposit in Harney County around 1980 marked a turning point. High-quality faceting material began entering the market, and the gem’s reputation steadily grew.

In 1987, Oregon officially designated Oregon Sunstone as the state gemstone — solidifying its identity as a uniquely American treasure of the high desert.
Modern Small-Scale Mining
Today, mining in southeastern Oregon remains largely small-scale and carefully managed. The Bureau of Land Management oversees a public collection area near Plush, allowing visitors to experience the thrill of finding their own stones. Private claims continue to produce exceptional material, much of it mined responsibly by families who have worked the land for decades.

That small-scale approach matters. It keeps the gemstone closely tied to its origin and allows jewelers like us to maintain transparency about sourcing.
From the Desert to the Jewelry Bench
What began as volcanic activity millions of years ago now finds its way into handcrafted pieces designed to last a lifetime. The range of color — from soft champagne to vivid red and rare green — makes each gem entirely individual.
We see that individuality most clearly in our Oregon Sunstone engagement rings, where no two center stones are ever exactly alike. For couples who want something deeply personal, we also offer custom jewelry design, allowing you to choose a specific stone and setting that reflects your story.

When you wear Oregon Sunstone, you’re wearing more than a gemstone. You’re wearing a piece of American geological history. A piece of Indigenous trade routes. A piece of frontier mining persistence. And a piece of the Oregon high desert itself.
