Gemstones & Pearls:News
The U.S. produces a bevy of natural gems that quicken the heartbeat.
Here are two
Raise the flag, light the sparklers and strike up the band to celebrate
the nation's independence this month. And while you and your customers are
in an all-American mood, why not promote gemstones of U.S. origin.
The U.S. produces some of the finest and most unusual gemtones in the
world, including the rediscovered Four Peaks amethyst with its royal velvety
purples and coveted flashes of red, and the copper-included sunstone, which
is unique to North America.
U.S. gem sources have always been enormously popular with jewelers who
recognize the "Made in America" cachet. Now some new developments
warrant a closer look at how these gems can enhance sales.
The Four Peaks deposit of amethyst near Phoenix, AZ, is legendary. It once
yielded large amethyst with red flashes said to rival fabled Siberian material.
Producers say such gems soon will be available again.
The mine, 7,200 feet above sea level in the Mazatzal Mountains, has reopened
under the auspices of the Four Peaks Mining Co. after a 20-year lull. The
faceted amythests will be distributed by Commercial Mineral Co. of Scottsdale,
Prices will be competitive with world market prices for amethyst, say
producers, particularly Zambian and Brazilian goods. The material will sell
for $35-$38 wholesale per carat for top qualities, $15-$25 for commercial
qualities and less for lower grades. Commercial Mineral Co. will issue a
certificate of guarantee of natural, U.S. origin with every stone.
Sunstone is about to go mainstream thanks to interest from major jewelers
such as H. Stern and Tiffany & Co., as well as from television shopping
Sunstone is mined in several locations by several producers in Oregon.
One attraction of sunstone is the "schiller effect," which gives
each gem a unique appearance because of the random arrangement of copper
platelet inclusions. American sunstone, a gem from the feldspar group, also
varies widely in color: ranges of orange, red, green and colorless are seen
most often. Clever cutters can combine these to show a multicolored gemstone.
While some sunstones are faceted if they have good body color or clarity,
most are calibrated, cabochon goods. Some exceptional pieces are used in
Pricing is difficult to pin down because each gem is unique. However,
small commercial goods can sell for $6 to $20 per carat wholesale; more
saturated, unique gems range from $20 to $90 per carat. Much larger, fine
gems are negotiated individually. American sunstone is not treated or enhanced
in any way.
