Description
A stunning emerald step cut on this transparent white sapphire from Ceylon. Light silk inclusions don't take away from the breathtaking beauty of this sapphire from Ceylon. Certified by the AGTA as natural and untreated.
This
gemstone (or gemstone that is part of this piece of
gemstone jewelry) has NOT been enhanced by
traditional heat treatment or any other known enhancement
. The
only way
to tell if a
colored stone
has been
treated is for the
stone to
be
analyzed by a lab.
Generally only
gemstone laboratories
have the
equipment
necessary to make
a
qualified
judgment with any
certainty.
Untreated
gemstones are rare and should be verified by a lab
independent
of the seller. A good
rule of thumb is to
always assume a
gemstone has been
enhanced, unless
valid
certification
from a reputable
laboratory is
available.
No
one that
sells jewelry or gems
should be
doing appraisals,
certifications, or
analysis. It
should always be an
independent
third party
with no
vested interest
in the
sale.
