The word "sapphire" comes from the Greek "sapphires", which means blue, and many
people think that about sums it up. However, sapphires come in many colors -
especially sapphires from Montana, which run through a wide spectrum of truly
amazing shades. In its pure state, corundum, is colorless. Naturally, occurring
tiny amounts of trace elements create the variety of color found in sapphires.
The blue comes from titanium and iron. A small amount of chromium yields a pink
stone, iron gives rise to both green and yellow stones, while the combination of
iron and chromium renders orange stones. Heating gemstones to yield color
brilliance dates back to the beginning of time. Pliny the Elder, in the first
century A.D. described how Romans cooked the stones. A 1240 A.D. Arab treaty on
ruby heating in Sri Lanka describes similar techniques to those that are used
The exception is that there is now a modern breakthrough method for creating the
clarity and brilliance in today's Montana sapphires. Sapphires from Montana are

best known Montana sapphire mine is Yogo Gulch, the state's only primary
corundum source. Primary, meaning that a gem being mined is still embedded in
the rock where it formed and that this rock is still in its original location.
If that host rock had eroded fully or partly and its gem contents have been
moved by water or rockslide to some other area, this new site is called a
secondary source or "placer deposit." In recent years, most of the sapphires
from Montana have been coming from secondary sources. The sapphires found in
these secondary deposits are vastly different in color and character from those
found at Yogo Gulch. Hence, gemologists now distinguish between Yogo and other
Montana sapphires. Yogo Gulch was discovered about a century ago, on one of the
gravel bars on the Missouri River near Helena, Montana, by gold prospectors who
cared very little for the brightly colored pebbles they found. The first Yogo
sapphires were found very near the original dike in which they formed roughly 50
million years ago. In 1900, Yogo sapphires exhibited at the Universal Exposition
in Paris won a silver medal in competition against stellar stones from Kashmir
and Ceylon. Those prizewinning Yogo sapphire stones were hand-chosen by owners
of the Yogo Gulch mine, then in its first full year of production.
Yogo sapphires enjoy
a reputation for distinctive "cornflower" blue color as well as the rare
distinction of being treatment-free. Yogo sapphires do not need the color and
cosmetic boost from heat treatment, which is routinely given to blue sapphires
from Asia, Africa, and Australia. Because of their rare and natural beauty, Yoga
