| But Simanton points out that those
elements won't be "evaluated quite the same way. There is not an international
system for grading colored stone like there is for diamonds."
Colored stones are more likely to contain flaws and
are rated by the flaws you can see with the naked eye, says Ehrenwald.
Rubies and sapphires should be "eye clean to moderately included under magnification," he says.
With emeralds in particular, a flawless stone should
make you suspicious. "If you see an emerald that looks beautiful
and clear, be sure to get a laboratory report to verify whether
it's natural or has been treated," says Simanton. "It
should be verified."
Color and richness are big factors, too. With emeralds,
you want a richly saturated medium green color, says Ehrenwald.
For
rubies, look for rich tones that run the gamut from orangey red to purplish red.
"The more pure red it is, the more valuable it would be," he says.
With sapphires, look for a medium- to medium-dark-toned,
well-saturated blue color, Ehrenwald says.
Rubies and sapphires are sometimes heat-treated to
produce the desired rich color. The effects are permanent, and there
is nothing inherently wrong with heating, as long as it's disclosed
to the customer -- and "providing nothing foreign has been added
to the stone, such as glass filling," says Ehrenwald. "If the
color is from nature and untreated it will be much more expensive,"
he says.
Fracture
filling "is more a negative thing," says Ehrenwald. "On the other
hand, these treatments do allow colored gemstones to be affordable. However the
stability of fracture filling is questionable."
And the origin of the stone can make a difference.
Labs can usually tell where a stone is from by the telltale signs
inherent within the gem, says Ehrenwald. Top rubies come from Burma,
Africa and Thailand, then the rest of the world, he says. The best
emeralds are from Colombia. And the premier sapphires hail from
Kashmir, followed by Burma, then Sri Lanka, then Australia.
Smart shopping
"The
key that distinguishes jewelry from every other industry is that jewelry requires
the expertise of a trained professional," says Ehrenwald. When
it comes to jewelry, you have to have a certain amount of confidence in the seller.
Does the retailer have a reputation for good jewelry? Is the store a member of
a professional organization, like Jewelers of America, the Jewelers Vigilance
Committee or the American Gem Society, that espouses a code of professional standards
and ethics? Does it have certified gemologists on staff? Do you get a description
of the stone or piece from an independent gemological institution? Retailers
need to guarantee that the piece is genuine and allow for returns in case you
or your giftee isn't satisfied. Ehrenwald recommends getting
a report from a recognized and well-established gem lab.
If it's a less-expensive piece and the seller doesn't
want to provide a report, "all the information should be written
on the sale receipt," he says. What you need: a complete description
of the piece, "the more descriptive the better," he says.
"It's a legal document." So if you discover that those
"cultured pearls" are imitation, there's something in
writing.
Certification
is the key to making a good buy, Ehrenwald says. It allows consumers "to
compare, which is really great for shopping."
