I admit that I can no longer be 100% assured that any stone I
purchase to recut has not been enhanced. My opinion is also that
neither can any other gemstone dealer. Other dealers are exploiting
the weak spots in the evaluation process for their own personal
gain. In rough I feel slightly more secure, but be advised I have
heard that in San Palo (Sp) Brazil they are experimenting with
radioactive treatment of a lot of gemstones in the rough.. I do not
know what is going on in Africa or Thailand as they are very tight
lipped about any enhancements. I also know that gemstone treaters
are traveling the world buying stocks of rough for treatment."
Hi Gerry (and gang), While you and I have often had widely differing
opinions on various topics, I couldn’t agree with you more, on this
one. About four years back, I had a (shall we say) “extremely lively
and diametrically opposed discussion” with the late Mark Liccini,
who staunchly believed it was (quote) “every lapidary’s duty to do
whatever it takes to coax the best possible appearance out of
whatever comes out of the ground, whether that means heating dyeing,
filling, irradiating, as well as faceting, cabbing, carving or
reconstituting”. I disagreed vehemently with him, and still try my
best to be as altruistic as possible. But, at the same time, I have
to admit, in my heart of hearts, that I know that only Garnets
remain (to the best of my knowledge) the one fundamentally unchanged
gem species. All other gem materials currently available, to the
best of my knowledge, are either commonly treated or very frequently
so.
The source of the problem lies in the combined blessings and curses
that the various mass merchandisers on TV created back in the
early-to-mid ‘80’s, by generating mass markets for materials which
are now, and have always been, rarities. Think back to your earliest
studies of gem materials… back to the “old” definition of the
criteria which determined a particular mineral or rock’s status as a
“Gemstone”, prior to this onslaught of enhancements: beauty,
durability and rarity. When I began collecting minerals, in 1965,
and cutting, back in ‘72, the number of gems which were routinely
treated were relatively few, and the comparatively primitive nature
of the majority of those treatments made them readily identifiable
by those with even the most fundamental understandings of what the
respective gems’ features were, or should have been. When the
initial one of these videomarketers hit the market, it worked its
magic by dangling scintillating baubles before the eyes of lower to
middle-class Americans (and other nations’ viewers as well, I
suppose) and gently reassuring them that they, too, could live like
the “Rich and Famous” for just a few dollars per credit card
installment.
The only problem with this approach is that, as Amsterdam Sauer’s
founder once pointed out, “Gems are a one-time harvest”; once you’ve
built your market, you’re well on the way to losing it, unless you
can “miraculously” come up with new sources of supply. In the
colored stone world, this has meant a choice between either newer,
more technically advanced ways of treating the poorer qualities of
undercolored or included rock that used to be discarded, or coming
up with ways of either imitating or replicating it in the
laboratory. And as for those Topazes? Just within the last three
weeks, I’ve seen several samples of absolutely exquisite Imperial
Topazes – lush, pinkish-golden to apricot-hued roughs – whose
colors so exactly duplicated the crystals my folks brought back from
their 1974 Brazilian vacation that my first tendency was to
salivate!
…And then, I realized that there was just one small problem with
the pictuRe: the crystal habits were all wrong for Brazilian
Topazes. So, in which shade did these originally begin their
journeys? Like the majority of the radiologically-enhanced Topazes,
Amethysts, Citrines, Smoky-, Rose- or Praisolite (a.k.a. “Ouro
Verde”) Quartzes, Tourmalines, Aquamarines, Morganites and Green
Beryls Mr. Liccini used to sell to eager buyers, my guess is
white/colorless. Should this be cause for some kind of uprising
amongst us all? I guess that depends on your your answer to one
simple question… now that most of the natural gem resources have
been either diminished or depleted, would you still like to sell
quality colored stone items that retail for less than a thousand
dollars apiece? (It bears consideration.)
