Sarah O.'s Limited Edition Hand-Mined Montana Sapphire Engagement Rings

Some jewelry collections are beautiful. Others carry a story that makes them unforgettable. Our newest Montana Sapphire collection is both—a limited-edition release rooted in adventure, intention, and the quiet magic of a stone pulled from the earth by hand.

This collection started, quite literally, in the dirt. Last year, Sarah and Hannah packed their boots and their curiosity, and headed to Montana—where sapphires can be sustainably mined in the wild. With help from local experts, they sifted through gravel and sorted stones by hand, uncovering a small batch of rough sapphires that stood out instantly. Each one had a unique color, shape, or sparkle that hinted at something special, and they knew right away they wanted to bring these gems back to Colorado to create something truly meaningful.

Back in Denver, each stone was carefully cleaned, cataloged, and sent to our trusted cutters—experts who coax out the unique beauty within every facet. What returned were six one-of-a-kind sapphires, each with its own personality, shape, and shade—ranging from oceanic blues to deep violets and warm, sunset-like tones.

But the story didn’t end there.

We took each sapphire and paired it with a Voyage setting—a Sarah O. signature known for its dreamy shapes, romantic halos, and modern heirloom appeal. The result? Six rings. Six chapters. Six wearable works of art that carry the memory of that Montana trip in every sparkle and stone.

Meet the Collection: One-of-a-Kind and Full of Soul

Atlantis 1.42ct Long Oval

A mystical sea-blue sapphire with a softness that feels otherworldly. Set in a feminine halo, this piece is for the dreamer, the water sign, the old soul who believes in lost cities and found treasures.

Dillon 1.20ct Pear

A golden-peach glow with inner fire, Dillon is equal parts warmth and whimsy. Set in a Voyage halo, this ring is perfect for the romantic who’s drawn to glow over glitter.

Nessie 1.34ct Oval

Named with a wink toward folklore, Nessie is playful and mysterious, with a moody blue hue that shifts ever so slightly in the light. A ring for the bold-hearted explorer.

Nile 1.04ct Cushion

Classic and clean with just enough edge, this cushion-cut sapphire recalls cool river waters and timeless elegance. She’s the minimalist’s statement ring.

Nile 1.04ct Round

More than meets the eye. The round-cut Nile stone is a deep lake blue, set in a setting that twinkles like a night sky. A piece for the quietly powerful.

Victoria 1.72ct Long Pear

Regal, moody, and full of depth, Victoria is the crown jewel of the collection. With its elongated shape and shifting shades of violet and blue, this ring is made for the spotlight.

Why It Matters

At Sarah O., we talk a lot about jewelry with meaning. But this collection is something more. It’s the physical result of women in the wild— mining the earth, trusting the process, and creating something beautiful from scratch. Each ring is a reminder that the most precious things take time, intention, and a little bit of dirt under your nails.

These are not just sapphires. They’re stories you can wear. And when they're gone, they’re gone.
