Montana's Gemstones
&
Fine Jewelry

Wear a piece of Montana!
We specialize in custom jewelry --
please call us for an appointment.

   Although GemLand's inventory includes diamonds and gems from around the world, we specialize in precious stones mined in the United States.
   While not commonly known around the world, Montana produces some of the finest sapphires -- those from the famous Yogo Mine, in the central part of the State.  Once owned by the British, gems from Yogo are to be found in the Crown Jewels.
   Besides their beautiful color, described as "cornflower blue", they are the only currently mined sapphires in the world that are natural and not heat-treatedBecause of this, they are also among the most valuable!
   The Yogo Mine operates seasonally, and does not produce a large inventory.  Therefore, you must check with us for currently available sizes and shapes.
   Please remember that custom jewelry is our specialty.  Contact us to create a piece of lasting beauty for you or your special someone!

   Pictured at right is Yogo Gulch, looking upstream from the mining areas.
   The nearest city with a large airport is Great Falls, some sixty miles (~100 km) to the northwest.

Yogo Gulch in central Montana -- source area of Yogo Sapphires.

Yogo Sapphire crystals, as found in Yogo Gulch, Montana -- natural, non heat-treated gemstones.

   Volcanic structures known as diatremes contain stunningly blue, clear crystals (at left) within a matrix not unlike that within which diamonds are found.
   After the rock breaks down, the ore is washed by water, and sapphire crystals like those at left are retrieved.  They require no treatment of any kind to enhance their beauty, and are nicely  complemented by rich Yellow Gold.

Yogo Sapphire and Gold Jewelry, from Yogo Gulch, Montana.

   Above is a very well done piece of Montana jewelry art. 
   This men's ring not only has a quality oval sapphire; it is framed by natural gold nuggets -- another legacy of Montana's riches.
   However, because of their superb clarity, Yogo Sapphires are typically cut in a round brilliant fashion, like diamonds, enabling more brilliance and sparkle.

   We think that part of the appeal in possessing any object incorporating stone is its connection to a particular place.  This is especially true of precious gems.
   When you are wearing a Yogo Sapphire, you are wearing a little piece of Montana, with its great history and geology!
