🏡🪏We are a small family mine, emphasis on family. Mining has been in our blood for generations, and while it started with gold panning, we are teaching the art of sapphire sifting to the next generation. Here we have Papa Tony teaching his granddaughter the washing technique that helps settle all those heavy sapphires to the bottom so they’re right on top at the flip. This is how we spend our weekends. What are some of your traditions? 🗣️👇🏼

Painting with earth's palette. 🎨⛏️

A closer look at the natural diversity of our rough material.

Most of these are rough sapphires, but you'll notice a few deep red pieces in the mix too. Those are either garnets or possibly rubies—technically, ruby is just the red variety of sapphire (corundum), to though raw stones don't always give away their exact identity right out of the wash plant.

No heat, no treatment, just raw stone as it comes out of the gravel. ⛏️💎

Notice anything unique about the center of this round brilliant? 🔍💎

Most rounds feature a standard 8-sided table, but for this 0.7 ct icy blue sapphire, we went with a triangular table for a fresh, geometric look.
The table of a faceted gem is the flat facet right at the top.
Faceting 101: Think of the table as a gem’s window. It lets light enter the stone so it can bounce off the bottom facets and shoot back to your eyes as pure brilliance. Changing the table’s shape alters the geometry of surrounding facets, creating a totally unique reflection pattern.

Did you notice it right away?

Small stone, massive character. ✨🌿

Highlights from this 0.44 ct square cushion cut natural Montana sapphire—it’s the ultimate mood shifter! Under indoor lighting, it glows with a warm, golden ch*****ne-green tone. Step outside into natural light, and it instantly transforms into a slick, moody gunmetal blue.

Shown loose on the hand to give you a true feel for its scale and sparkle out in the wild!

Which side of its personality is your favorite—golden ch*****ne or gunmetal blue? Let us know in the comments! 👇

Chasing the dream of true “Single Source” jewelry, starting right here on the Mt. Baker Mining and Metals Equipment shaker table. ⛏️✨

While gems are our main trade, our mine produces a surprising amount of gold! The tricky part? It’s super fine “flour” gold, trapped in exceptionally heavy black sands packed with dense minerals. Separating it requires fine-tuning, constant tweaking, and plenty of patience! 👨‍👦⚡️

We’ve already begun perfecting the smelting and refining process for the gold we’ve separated over the last few seasons but it remains a project on a small scale. Our ultimate goal? To craft pieces where the gold is mined, refined, smithed, and set with precision faceted gems mined and cut by us all in house.

Step by step, we’re making it happen. Thanks for following along on the journey! 🌿💍

One loose sapphire, endless personality. ⚡️💎

Here’s a quick on-the-hand preview of a 1.1ct oval Montana sapphire doing what Montana sapphires do best—shifting seamlessly between colors in different lighting. This one dances between a light aqua and a midtown steely periwinkle.

Since it’s still loose, the design possibilities are entirely up to you. Solitaire, bezel, three-stone setting... what would you build around this gem? 💍

Behind the scenes at our daily grind. ⚒️ Dialing in the water flow and keeping all the moving parts balanced is a continuous job. It’s loud, wet, dirty, honest work, but standing out here hearing the plant hum and wondering what will be waiting for us at clean-out at the end of the day makes every second worth it. 💎 ✨
