HOW
TO CHOOSE
When choosing a star
ruby for use in jewelry, select
one of gem quality if possible,
or at least of jewelry quality,
with as pure a red color as
possible.
Next, considering the appearance
of the star and the stone's
overall shape and form, choose
a gem that appeals to you.
The key is to emphasize the
color while keeping in mind
that, especially in the case
of star ruby, there is no such
thing as a perfect stone. Usually,
the deeper the red color is,
the weaker the star will be.
A stone in the 10-carat range
with a deep red color and high
level of transparency, as well
as a distinct star, is something
that is rarely encountered.
Take care to avoid buying loose
stones with bases that are
too deep, since this will cause
problems during setting.
The value of a three-carat-size,
heat-treated star ruby of jewelry
quality is approximately US
$5,000 for the stone alone.
