Where are Yogo Sapphires Found and How Are They Mined?
Yogo Sapphires are exclusively found in the Yogo Gulch, located near Lewistown in central Montana. With no surface outcroppings, these gems can only be mined by hard-rock mining, which involves digging deep shafts into the earth. This process is typically done by hand and the results often bring forth the most treasured Yogo Sapphires - gemstones of beautiful blue colors and eye-clean clarity.
The Beauty and Rarity of Yogo Sapphires
Yogo Sapphires are truly remarkable gemstones. They are renowned for their captivating beauty and color variations that range from cornflower blue to bright electric blue to a deep velvety violet hue. Most importantly, the color of Yogo sapphires is completely natural. Unlike 99.9% of all the sapphires in the world, Yogo sapphires are not heated or treated in any other way to enhance their color.
