How it Works

Joe Hand Picks Every Stone

Joe is our exclusive Gritologist. He hand-sorts Montana sapphire concentrate, primarily from Rock Creek and the Missouri River, and picks the stones worth keeping. One named person, doing careful work on every parcel that comes through.

We Document Everything

Every loose Montana sapphire gets a Stone Passport: weight, dimensions, color, cut, and heat treatment status. Unheated Montana sapphires are marked unheated. Heat treated stones say so. No ambiguity. Every stone was mined by Joe through years of hard work and comes with a Certificate of Authenticity validated by the state of Montana.

Our Promise To You

A completely unique Montana Sapphire experience. Each stone comes with a Certificate of Authenticity affirming it was found and approved by Joe himself along with a unique QR code to maintain it's historic provenance and value.

Meet Joe - The Person Behind Every Stone

Joe is our exclusive Gritologist; we like to call him our Grit Kicker. He was a welder before he was a rockhound. He pulls primarily from Rock Creek, specifically Gem Mountain, and occasionally the Missouri River, the same deposit that produces some of the most sought-after American sapphires in the world. Every stone on this site came through his hands first.

Read Joe's Story

Every Montana Sapphire Stone has a Passport

Six fields on every product page: Stone ID, weight, dimensions, color, cut, and treatment status. Unheated Montana sapphires are labeled unheated. Heat treated stones say so clearly. We tell you what we know about every ethically sourced Montana sapphire.
