1Montana Sapphires History
Montana has a rich history of sapphire mining, with the first discovery in 1865 by gold miners near Helena. Over time, more deposits were discovered throughout the state, including the famous Rock Creek deposit.
Rock Creek Sapphires are known for their unique colors and high quality. The deposit was first discovered in 1892 by miners who noticed small blue stones while digging for gold. Soon after, sapphire stone mining became a major industry in Montana with over 200 active mines at its peak.
Although mining was interrupted during World War II, it resumed after the war and continued until the 1980s when foreign competition made it difficult to compete economically. Today, Rock Creek Sapphires (Missouri River) are still sought after by collectors and jewelry makers alike for their beauty and rarity.
2Montana Yogo Sapphires
Montana Yogo Sapphire is a rare and prized gemstone amongst all Montana Sapphires. These sapphires are unique due to their naturally rich blue color, which is not typically associated with rough Montana sapphires and considered to be extremely rare. The blue-green color of Montana Yogo Sapphires is caused by the presence of iron and titanium within the stone which is sometimes also considered and called Teal Sapphires.
The name “Yogo” comes from the location where these sapphires were first discovered – Yogo Gulch in Montana. The area has been mined for over 100 years, but it wasn’t until 1984 that the unique properties of these sapphires were fully realized. Since then, they have become highly sought after by collectors and jewelry designers alike.
The rarity and beauty of Montana Yogo Sapphire’s intense colors make them a valuable addition to any collection or piece of jewelry.
3Montana Sapphire Treatments
Heat treatment is a common practice in the gemstone industry that involves heating a stone to high temperatures to improve its color or remove impurities. In the case of Montana sapphires, heat treatment can significantly enhance their blue hue and make them more vibrant. This process is done using specialized equipment in a controlled environment by experienced professionals.
It’s important to note that heat-treated sapphire does not affect the durability or value of Montana sapphires. It simply enhances their appearance by bringing out the natural beauty that is already present within the stone.
