What is unique about these Montana Sapphires?

Montana Sapphires are unique because they are a precious gemstone from the United States, and they come in colors and color combinations that don’t occur in other locations on the planet. They are a highly ethical choice as we procure the sapphire with stone that comes directly from the miners, some of whom own their own mines. North America is full of beautiful rough stones and Montana is home to Gem mountain gold mine, Sapphire mountains, Dry cottonwood creek. These unique landmarks in the state reflect the production of Montana's finest precious gemstones such as the Rock creek sapphire.

What are these natural sapphires made of?

Sapphires are from the gemstone family corundum, which is a mineral also known as aluminum oxide. The aluminum oxide is traced with iron and titanium to form the corundum. After diamonds, corundum creates the second hardest natural substance. A sapphire is formed when the corundum comes in contact with other minerals, this is when the color starts to appear. Sapphires are typically found in metamorphic rocks due to the high levels of aluminum.

How to clean rough Montana Sapphire ring?

We have detailed care and cleaning instructions for your Montana sapphire ring here.

At home: Rings in particular tend to collect dust and soap behind the stone, especially if worn daily. To clean diamonds and transparent crystalline gemstones, soak them in water with a smidge of non-detergent, mild soap like Dr. Bronner's unscented soap or Meyer's Clean Day. Finally, rinse and pat dry with a clean soft cloth.

Professional: Professional cleanings are good occasionally. To schedule a cleaning reach out to our customer care team to coordinate. If it's not us doing the cleaning, please talk to the jeweler who is about the particular gemstone before they use an ultrasonic cleaner.

What are Montana Sapphires?

Montana Sapphires are simply sapphires that originated in Montana, USA. A lot of people don’t know that we have these beautiful gems in this country. The gem-quality sapphires are most prominent in central Montana. Montana, also known as the treasure state, is known for having two types of beautiful sapphires; Yogo Sapphires and fancy Montana Sapphires. The Yogo Sapphire is a blue sapphire found primarily in the Yogo Gulch. Yogo Sapphires are known for their blue color, high clarity, and brilliance under artificial light sources. Yogo Sapphires can be found specifically in the Yogo Creek while other Montana Sapphires are found in places such as Rock Creek. These sapphires were discovered by gold miners who mined near the Missouri river in the late 1800s. For years, the blue pebbles were ignored during gold mining but after 10 years they were finally classified as Missouri river Sapphires. Soon after this, sapphire mining became popular.

Are Montana Sapphires good for everyday rings?
