Since we’re still fawning over yesterday’s post, we wanted to share a few more colors making their way through this new calibrated shape.

This time, it’s Montana Sapphire - denim blues, teals, and greens each bring a completely different personality to the crescent moon, proving just how much color can influence a design.

Since this is still a new shape for us, drop a comment with your favorite so we know what to continue focusing on moving forward!

Back in Tucson, we introduced a brand-new shape. 🌙

Now, a small selection of our crescent moon cut in Australian Sapphire has made its way to our website. Inspired by the night sky, this distinctive cut pairs graceful curves with the natural beauty of Australian Sapphire.

Currently available in deep blue 5x3mm and 6x4mms, this is just the beginning of one of our newest calibrated cuts.

Also available, but not yet online: additional colors of Australian Sapphire and various colors of Montana Sapphire.

Mined from Montana's legendary Yogo Gulch, these 4x2mm Yogo Sapphires are completely natural—no heat, no treatments, just color created by nature. While the vivid blues are what Yogos are known for, every so often a rare lavender or purple gem sneaks into the mix.

A small stone with a pretty remarkable origin.

Every turn reveals something new.

A flash of green. A spark of orange. A streak of red. This baroque Mexican Fire Opal keeps the colors moving, creating the kind of play-of-color that makes these opals so endlessly captivating.

One of the things we love most about these Moss Agate Bullet Cabs is how personal the stone can be.

Some people see forests. Others see mountain landscapes, drifting clouds, or abstract paintings. The same stone can tell a different story depending on who's looking at it.

That's part of the appeal of working with a gem that nature designed first.

A vibrant blend of blues, teals, greens, and soft yellows gives these 4mm Kaleidoscope Nigerian Sapphire rose-cut rounds their signature look. Paired with softly glowing rose-cut facets, every stone offers its own unique play of color and light.

Anyone else finding themselves drawn to rose cuts lately? ✨

Proof that great things come in small packages. ✨

These 3–3.5mm dark teal Montana Sapphire hexagons combine rich ocean-inspired color with bold geometry, creating gems that feel both natural and unmistakably modern.

Tiny? Yes. Easy to overlook? Not a chance.
