Here’s What Makes a Montana Sapphire So Special
When it comes to fine jewelry, few stones feel as honest, grounded, and full of soul as a Montana sapphire.
Pulled from the rivers and mountains of the American West, each one holds a history that’s as rugged and rich as the land it comes from. They shimmer in unexpected shades of blue, green, teal, and even lavender, and no two are ever the same. But what really sets them apart isn’t just their beauty, it’s how they’re sourced, cut, and cherished.
At Rigby Leigh, we choose Montana sapphires not just for their color and character, but for their ethics. These gems are mined responsibly, cut by hand, and treated with the respect they deserve, all the way from a rough stone to a finished piece.
If you’re looking for something with more soul than sparkle alone, here’s why a Montana sapphire might just be the gem you’ve been searching for.
Characteristics of Montana Sapphires
What exactly is a Montana sapphire?
Montana sapphires are naturally occurring gemstones found in—you guessed it—Montana.
The most well-known sources are four key regions: Yogo Gulch, Rock Creek, the Missouri River (El Dorado Bar), and Dry Cottonwood Creek. These deposits produce some of the finest sapphires in the world, each shaped by the land they come from.
The stones we work with at Rigby Leigh are Montana sapphires—beautiful, naturally colored gems sourced from the mountains and rivers of Montana, a few hundred miles from where we cut them.
Color, character, and charm
Unlike traditional sapphires that lean heavily blue, Montana sapphires span an incredible color range: deep ocean blues, forest greens, soft teals, buttery yellows, moody lavenders, and even rare color-shifting stones that can change in different light.
While many gemstones are prized for their perfection, Montana sapphires proudly embrace their quirks and their imperfections are part of their charm. They have a wild, organic beauty to them that we find endlessly inspiring. No two are ever the same.
Durable enough to wear every day
Sapphires rate a 9 on the Mohs hardness scale, making them one of the hardest natural gemstones just behind diamonds. That means they’re strong enough for daily wear, whether you’re choosing one for an engagement ring, necklace, or heirloom piece. This is one of the reasons we use them in so many of our one-of-a-kind jewelry pieces.
A brief history
Montana sapphires have been part of American history since the late 1800s. During the gold rush, miners along Montana’s rivers kept pulling up colorful stones they didn’t recognize, until they realized they were sapphires. What was once seen as a nuisance ended up becaming one of the state’s most prized natural resources.
Ethical and Environmental Considerations
Many people don’t realize this, but Montana sapphires are some of the most ethically sourced gemstones you can find.
Sustainable practices
Most Montana sapphire mines are small-scale operations that prioritize land restoration and avoid heavy chemical use. Because the stones are often found in gravel near the surface, extraction has a lighter environmental footprint than traditional deep-earth mining for other gemstones like diamonds or emeralds.
Full traceability
Unlike many imported gems that can have murky supply chains, Montana sapphires are mined and cut entirely within the U.S., under strict labor and environmental regulations.
At Rigby Leigh, it matters to us that the stones we work with are not only beautiful, but responsibly obtained, and our customers feel the same way.
A lower carbon footprint
Since these stones don’t travel halfway around the world to reach us, their carbon footprint is much smaller than gems that are mined in one country, cut in another, and sold in a third.
How We Work With Montana Sapphires
At Rigby Leigh, every Montana sapphire we use is hand-cut, one at a time, by our founder David Watkins. He uses a vintage faceting machine built in Detroit in the 1940s, which is an old-school tool that matches his old-school approach.
“It’s a machine with character and history, and I’ve changed very little about it.” — David Watkins
Rather than forcing a gem into a standard shape, David studies each stone’s rough form, listening to what it “wants” to become. Some stones want more curve, others more edge. Basically, no two are the same, and that’s the point.
“It may sound strange, but each stone seems to tell me what it wants to become—what parts to emphasize, which angles to follow.” — David Watkins
Our jewelry is cast using an ancient wood-carving technique that leaves behind the texture of the wood in the gold. We use only Harmony Recycled Gold from Hoover & Strong, and antique diamonds when possible, to keep our commitment to sustainability strong and transparent.
“It’s a slow and meticulous craft, but that’s exactly what I love about it.” — David Watkins
