Under the Microscope
Important
gemstone industry issues took center stage at Tucson conference.

...Although
they’ve been on the market for many years, lead
glass–treated ruby continues to plague the industry with concerns. A
buyer-beware report that aired prior to Christmas on “Good Morning
America”
alleged that inexpensively priced glass-filled rubies were being sold
at Macy’s
without disclosure...

Putting Things in Perspective
(owner of All That Glitters Comments)
Yes, MANY Rubys are glass filled, especially those coming from
Madagascar. This is similar to the Oiling of Emeralds, and
improves
the clarity of the gemstone by filling cracks. Unlike Oiling,
this
glass filling is more stable when ultrasonic and/or steamed
cleaned.
However, the trade does believe that treatments/enhancements
should be disclosed.
Since we have known that many Rubys are glass filled, our finer
important Rubys like our Burmese Rubys, have been tested and the
reports indicate heating (expected for the most part, as most Sapphires
are also being heated as well as most Tanzanites to create that blue
purple color. Aquamarines are typically heated to drive off the
yellow
component leaving a more true blue color behind). We don't feel
that
heat is really an issue unless someone seeks a non-heated
gemstone.
For the Burmese Rubys we have encountered, they have been heated in
borax which acts as a flux and if there are any pits, scratches, etc.
the borax will fill in these voids. The reports that we obtain
will
indicated the slightest 'filler' which in these cases is usually just
the borax filling in voids, and it is not glass. In fact, we have
a
beauty of a Burmese Ruby that did test out as having filler, but this
is borax and the amount was nothing to be concerned about. We
would
purchase similar gemstones because of the beauty, clarity, color,
etc.
However, while in Thailand, we have seen the glass filled Ruby coming
out of the ovens. The glass filling is used for typically the
poor
quality Ruby to make it marketable. At times, there may be more
glass
than Ruby! This is something that we have stayed away from -
though
for some in the trade as well as consumers, having a very large Ruby
that has passable inclusions and is glass filled, is ideal because of
the price usually associated with it, but the seller should
disclose
this fact.
All this said, it sometimes pays to know the exact questions to ask
when it comes to specific gemstones. In the case of Ruby, a
simple
question of - "Is it Natural Ruby" is not enough. Answering Yes
from
many sellers may indeed be correct - it is a natural Ruby, BUT, it may
have been Glass Filled, Heated, etc. Glass Filling or Heating has
nothing to do with Natural Origin - so the seller would have been
correct if the Ruby was indeed Natural and mined from the ground.
It
is the disclosure that is the issue. We have even read an article
written by an American living in Thailand who was indicating the
questions to ask - his question of whether it was Natural in
relationship to the Beryllium Treatment of Ruby or Sapphire was again,
not sufficient. He needed to ask not only if it was Natural, but
whether ANY treatment had been performed, and this would include Heat,
Glass Filling, Be Treatment, etc.
The other issue with asking questions about treatment, natural origin,
etc. especially in a store (and in the case of a large retail store
such as Macys), is that the person providing the information just
doesn't know. That information is typically lost or never even
disclosed. They might know that it is a Natural Ruby, but the
origin
and any treatments is beyond their knowledge. This is even beyond
the
scope of many selling gemstones in the very countries where dealers
like myself make purchases to disperse gemstones to the public and the
trade throughout the world. Many people in Thailand,
Brasil, African
and all other gem producing and cutting areas of the world, are selling
their wares to make a living or a profit to supplement their
income.
They are not gemologists. They have no idea at times about
treatment.
They are purchasing from other individuals who tell them perhaps only
one thing - it is a Ruby they are buying. Saying something is a
Ruby
too, doesn't mean that it wasn't grown in a
lab and is therefore a Synthetic Ruby. (A Synthetic Ruby is
indeed a
Genuine Ruby, just not of natural origin!) These sellers
don't know
if the Ruby originated in Africa, Sri Lanka, Burma, Madagascar or even
from North Carolina, never mind about any form of
treatments... They
are just concerned about buying an item for resale and have limited
knowledge.
This is why it is advantageous to purchase gemstones from those in the
know, who travel the world and see/read what goes on out there.
Buying
from those mining the rough gemstones or purchasing with only one
source between the miners provides All That Glitters with insight to
where something originated, what treatments might have been
applied.
If we have concerns, we will have it certed for verification of what we
were told or what we believe or suspect. This dealing direct with
All
That Glitters gives the trade and online customers a big foot up on all
other sources out there. The history, the origin, the treatment
and
much more is known in detail and hasn't been lost when purchasing from
one of the direct sources - All That Glitters.
Many times the information that a store has is limited, and the person
behind the counter may not have any information at all. They are
salespeople and are many people removed from the source. With All
That
Glitters, you are right on top of the source, where we may have even
faceted the gemstone from the rough. Again, know those you
purchase
from. We have a 7 Day Satisfaction Guaranteed Policy, not
to mention
our
LIFETIME Guarantee. We do our best to provide you with all the
information we know about a particular gemstones. What you
purchase
from us today, may be returned at any time for
non-disclosure. Buy
direct from those who shield you from issues and be safe in the
knowledge that you won't have to worry or question your purchase...
