The Yogo sapphire's formation is an intriguing geological process that contributes to its uniqueness among gemstones. Unlike many sapphires, which typically form in metamorphic or igneous rocks, Yogo sapphires have an origin tied to a specific type of geological occurrence known as a "lamproite diatreme."

During the explosive eruption, the molten lamproite magma rapidly reached the surface, bringing with it the corundum crystals that would later become Yogo sapphires. The rapid ascent and cooling of the magma contributed to the unique color and clarity characteristics of Yogo sapphires.
What sets Yogo sapphires apart is their remarkable consistency in color and quality. The Yogo Gulch deposit is renowned for producing sapphires with an intense, cornflower blue hue that is both vibrant and velvety. This consistency in color is unusual in the world of sapphires, making Yogo sapphires particularly prized among gemstone enthusiasts.
Furthermore, Yogo sapphires often display exceptional clarity due to the rapid cooling of the lamproite magma. This quick cooling prevented the formation of large mineral inclusions, resulting in sapphires that are not only intensely blue but also notably transparent.
The combination of the unique geological conditions and the specific attributes of the Yogo Gulch deposit contributes to the distinctiveness of Yogo sapphires. Their rarity, vivid blue color, and exceptional clarity make them highly coveted and stand out as one of the most cherished gemstones in the world.

Around 60 million years ago, deep within the Earth's mantle, lamproite magma began to rise towards the surface. As it ascended, it carried with it a variety of minerals, including corundum, the mineral responsible for sapphire and ruby. The molten rock then encountered a weakness in the Earth's crust, creating a violent and explosive event known as a volcanic pipe or diatreme.
