Stones of Fate and Fortune : Topaz of Brazil

imperial topaz >.....which confirms my suspicion that this is
simply a marketing >term. 

Absolutely. The word “topaz” is a mineralogical term and it has a
specific meaning, but the term “imperial” is JUST a trade name and
there is NO UNIVERSALLY-ACCEPTED, specific definition of what it
means. Of course, there is a generally-accepted, vague understanding
in the trade of what it means, but that’s simply not good enough.

For example:
"Imperial topaz only comes from one mine in Brazil"
"Imperial topaz only comes from mines in one specific area in Brazil"
"Imperial topaz is any topaz with a pinky-orange colour"
"Imperial topaz is any topaz with a pinky-orange colour that doesn't fade"
"Imperial topaz is orange"
"Imperial topaz is pink"
"You can't call it Imperial topaz if it's been heat-treated"
"Imperial topaz may have been heat-treated"

Over the years, I’ve heard all the above statements (and more).
Such statements are contradictory and they can’t all be true! Until
the industry agrees on a definition, then we will have to take the
term “imperial topaz” with a very large pinch of salt.

"Bishop's Amethyst" 

Before the discovery of the Americas, amethyst was relatively rare
and expensive and was one of the most sought-after a bit
like sapphire. Shortly after they discovered the New World, however,
enormous deposits of amethyst were discovered in Brazil. The price
dropped very significantly: today, amethyst is generally perceived as
an affordable stone for daily wear, rather than a rare and precious
gem.

The Siberian deposits became famous in the 19th/early 20th century
(although I think they were probably discovered before then). The
African deposits were discovered later, and they didn’t really hit
the market until about the 1980s I think. I believe synthetic
colourless quartz was first manufactured for the military, and after
WWII they progressively improved the technology so much that we’ve
reached the point where a large proportion of the gem quartz on the
market is now synthetic (one recent estimate said at least one-sixth,
but some people say that it’s over 50%).

South American Emerald and gold finds were considered the sole
posessions of the monarchies which underwrote their claimers'
conquests. 

Broadly speaking, yes. Certainly, whenever valuable commodities
were discovered, the relevant Governor would usually immediately pass
a law. Such laws might say that a proportion of any find would belong
to the king, or that that commodity was Crown property. For example,
in Brazil, the law stated that all diamonds over a certain size were
the Crown’s property, and to possess one without immediately handing
it over to the Governor was a serious theft. Incidentally, since the
diamonds were Crown property, you would receive no compensation. Of
course, gem-hunters would try to keep as much as they could, by
concealment and smuggling!

Tony, From reading this thread it’s clear that this is a hot-point
issue for you. But I’d like to offer another opinion for your
consideration.

You take on, for example, “Pigeon’s Blood” as a designation for a
type of ruby. To me, it’s a concise description of color, just as
“Champagne” is a color designation for a citrine or diamond. When
someone says to me that something is a “champagne diamond,” I can
immediately picture the color of the stone being referred to.

Imperial Topaz works only because it has become a common descriptor
for topaz of that wonderful golden color. It may have started for
some obscure reason, but today most folks know that the Imperial
designation means that the stone is a higher quality deep saturated
color, originating in Brazil. The pale or colorless topaz originating
in Brazil is not called Imperial, so there’s not really any
confusion. It’s not like taking quartz and calling it “topaz” – the
stone is still topaz, just with a descriptive appellation.

Does this make it sit any easier with you?

Hello All- First, I bought a delightful book about 20 years ago
titled “Gems for the Taking” by Mary Brown. For me it remains the
single best reference (if a bit dated) for the often-colliding worlds
of Romance vs. Technicalities in the colored gem realm: Easily read
in small chapters, many historical anecdotes and not too much
technical claptrap while at the same time presenting the science to
the reader in laymans’ terms. It is richly-worded and actually a fun
book to read; I’ve made many sales through loaning the book to
clients for their reading pleasure.

I am recently-subscribed to this list, and it’s great to have
no-holds-barred discussion about many subjects. With twenty-five
years in the business ( or the hobby, depending on my depth of
involvement at the time), I’ve came across a vast array of "names"
describing certain highly sought-after gems. Some were merely
marketing tools, others have become synonymous with a specific type
of stone- many times signifying a specific geological/geographic
source. The “pigeon-blood” rubies have traditionally come from two
sources: The Mogok region of Burma (Myanmar) and the Cowee Valley
region of Western North Carolina. “Imperial” topaz has traditionally
described a specific color, regardless of geographical source,
although Russian and Brazillian sources are the most often cited.
“Kasmir” sapphire describes a color, and only rarely the geographical
locale of the mine. “Muzo” and “Chivor” emeralds, along with the
corresponding geographic designation of “Colombian” are indicative of
a green/blue color saturation which is nearly unique to the region,
making these stones so distinctive and more highly prized than
others. “Imperial” jade has traditionally indicated a degree of
translucency and hue which makes it much more desirable than other
types of jade. The list goes on and on, but many of these terms are
hundreds of years old and have a romantic association linked to
them, which increases their desirability, and we are in the romance
business. I believe that we should romance the stones when describing
our wares, of course, but when the difference between a significant
stone being a true “Pigeon Blood Ruby, Untreated” which (is so very
rare) commands a king’s ransom and a Thai/Indian ruby, which (has
invariably been heat treated before it leaves the country) sells for
a few tens of dollars per carat, we have a responsibility to
ascentain the origin of the stone. If you can’t get a straight answer
from your dealer/broker, then perhaps you need to find a more
informed and communicative supplier.

Cap Beesley of AGL has spent decades attemting to find the unique
compositional qualities of the finest gemstones which are referred
to by a specific moniker or geographic description. He has has some
success and has shared his findings on many occasions with the trade
and the general public, to demystify the hazy process by which we
judge the quality of colored gems. We have a responsibility to our
customers as well as our own reputations as experts in our chosen
trade to “Romance the Stone” without misleading or misrepresenting
the origin or method of enhancement (if that applies). If we don’t
know, then we need to ask the nasty questions of our
suppliers/importers- and if they don’t know/won’t say then it’s our
responsibility to find out or simply tell our customers that many of
these descriptive terms are simply that: descriptions. Many of them
are incorrect and downright misleading (ie: Balas Ruby, Bamboo Coral,
Herkimer Diamonds, etc), but deeply ingrained in the sales and
traditional marketing of these stones that it warrants some extra
time to make sure the customer knows what they are buying. It’s only
our reputation at stake, that’s all. ThaiGem was nailed to the
proverbial barn door a couple of years ago by US-led importers for
non-disclosure and outright misrepresentation of colored stones.
Their reaction was basically “So what? Here’s your refund, now shut
up…”, and it was not until they began to feel real heat from their
customers that they changed their tactics (albeit with poor grace).
How many sales were lost due to these mistakes? How many future sales
were lost by ThaiGem because of their desire to make a few extra
dollars? Can your reputations survive this if you are not taking the
time to keep the tradition of romance and jewelry alive while at the
same time disclosing all you know about its treatment and origin
(even if that is nothing)? What I have found in this context is that
the customer WILL purchase the stone(s), while at the same time
giving you your due as an expert who is concerned about disclosure.
That equates to Good Will and many future sales.

Thanks for the time and space for my first post,

    But I think it important to keep our language clear and
simple. "Montana sapphire?" - OK, because it came from Montana,
"pidgin's blood ruby?" maybe... just... but it's a value judgment.
"Imperial Topaz?" No way! 

First off, thank you all for your replies regarding ‘imperial
topaz’.

If someone sells me a Montana sapphire and its from thailand I’d be
upset. But when it comes to Imperial Topaz, the one from Ouro Preto
Brazil is superior in color and distinct in origin(the way it formed
in the ground). Hence why I started this thread.

I have some topaz sold to me by a chap in BC as ‘imperial’ and is
varying shades of yellow. I am attempting to determine if in fact it
was russian/other topaz or the goods from brazil to which I have
associated higher value(perceived value). Now if I take this stone
after determining its in fact from the Ouro Preto region, and sell it
with a beautifull story, thats my business! I don’t know right now,
without a proper and credible lab’s assistance, therefore these
beautifull stones sit in a dark dark place. Its all about the stones.
And pidgeon blood well, thats another research thread. The average
consumer won’t want to look at letters and numbers to describe color.
The fact that people use imagery to convey the beauty of a stone is
not misleading, it is marketing. I say yes way!

Respectfully,
Jon

  Imperial Topaz works only because it has become a common
descriptor for topaz of that wonderful golden color. 

Hi Karen, I understand your point but, ironically, your description
above shows exactly why it’s fallacious: In my mind, “imperial
topaz” is a common descriptor for topaz of that wonderful pinkish
gold color :-). See what I mean?

Beth

Imperial Topaz?" No way! 

If you don’t like “Imperial Topaz” try “Precious Topaz” which is
also a name that is used.

One thing is for sure - if you come to Brasil to buy stones and only
ask for Topaz - you will be shown white topaz or irradiated blue
topaz. If you want the other stuff - you will have to say the
“Imperial” word

it refers to rio grande topaz and imperial topaz along with
samples. I could find little difference between the two stones. go
figure 

rio grande topaz is a deliberate misnomer. It is Citrine Quartz and
is made from heating amethyst. It is usually a deep orange color.

Best regards,
Robert Lowe,
Lowe Associates - Brasil,

the stone is still topaz, just with a descriptive appellation.
Does this make it sit any easier with you?" 

Not really because people are offering heat treated and surface
coated (it’s so nasty!) topaz as “Imperial” and then pretending that
this has a special meaning.

They are scoundrels!

For example look on the TV shopping networks where “champagne”
diamonds are offered. These are heavily included brown diamonds -
often cut very thin so that a little light comes through - certainly
not the color most of us think about.

Pigeons blood is different - just - because it refers to color and
inclusion. That strange bluish red the stones have due to various
things such as pleochroism and rutile inclusions. Even so I’ve seen
people who should know better offering very ordinary stones using
this designation.
