From Tiffany's to the Crown Jewels
of England, YOGO's have become part of a rich and royal history.
In a world of increasing mediocrity, the YOGO continues to stand
out as the world's finest sapphire.
YOGO Sapphires--World Renowned for Their Unique
Qualities
Discovered in 1896 the YOGO Gulch
Deposit is the world's largest in situ deposit of sapphires.
The YOGO dike is 5 miles long and over 7,000
feet deep.
The YOGO Gulch Deposit located near historic
Utica, Montana, is the only source of YOGO sapphires.
Other sapphires found in Western Montana (known as "Montana Sapphires")
do not have the YOGO's cornflower blue color and brilliance and
usually are heat-treated by man to attain their color ...so don't
be confused.
Yogo sapphires are different from any other sapphire
found on the globe.
BRILLIANCE
Place a YOGO next to any other sapphire. The
YOGO jumps out at you with its fire and brilliance. The YOGO's clarity
is combined with Roncor's precision cutting to create a sparkling
treasure.
COLOR
YOGO's have become the color standard by which
jewelers define "Cornflower Blue", the most desired color for sapphires.
Moreover, unlike many other sapphires which are flawed by color
zoning (i.e. they have a varying shade of blue from one end of the
stone to the other). YOGO's have a uniform blue color throughout
the stone.
CLARITY
YOGO's are well known for their lack of internal
flaws. Unlike other sapphires, YOGO's were formed very slowly (over
50 million years) allowing impurities in the YOGO crystal to be
purged through intense heat and pressure.
NATURAL
and UNTREATED
Over 90% of the sapphires sold today have been
heat-treated (cooked) or diffused (surface modification) to enhance
their poor color and hide imperfections. Scientists have tried to
finish what Mother Nature failed to complete; however, don't be
fooled.
Only YOGO's have the consistent high quality
that makes artificial treatments unnecessary. Untreated sapphires
of high quality are valuable due to their rarity. YOGO's have appreciated
substantially over the years due to their rarity. Baker's Jewelry
together with Roncor , the mine property owner, protect your investment
in a YOGO by issuing a CERTIFICATE OF GUARANTEE that ensures your
YOGO is 100% natural and untreated.
