Untreated Blue Sapphire Gems

Clarity Grading:

Sapphire clarity grades are assigned when a trained, experienced gemologist examines the gem "face-up" under controlled lighting without magnification.

Sapphire clarity grades are assigned without magnification. Sapphire clarity grades are determined by an inclusion's visibility, or lack of visibility, to the naked eye. This is the procedure at the major Gem Labs.

This is in sharp contrast to diamond grading where 10X magnification is required.

The top sapphire clarity grade at American Gemological Laboratory is "Free of Inclusion" and the top sapphire clarity grade at Asian Institute of Gemological Sciences is "Flawless". According to the Gemological Institute of America's Revised Colored Stone Grading Lab Manual, the top clarity grade for sapphire is "Eye clean".

These grades are assigned when an experienced, fully-trained gem-grader is unable to see any inclusions under ideal lighting conditions and without magnification.

When examined under magnification, almost all sapphires show some natural inclusions, regardless of whether these inclusions are visible to the naked eye. So, a sapphire that is honestly graded "Flawless" or "Free of Inclusion" or "Eye-clean" almost certainly contains inclusions at some level of magnification. (As do most Flawless diamonds!)

10X is the basis for diamond clarity grading.

Naked-eye is the basis for sapphire clarity grading.

Diamonds and sapphires almost always show natural inclusions if the magnification is high enough.

  Flawless Lightly IncludedL Moderately IncludedL Highly IncludedL Extremely IncludedL

Flawless Sapphires show no inclusions to the unaided eye when examined by a trained, experienced grader using an ideal light source.


Lightly Included 1 (LI1)
is the next clarity grade below Flawless.
Lightly Included 1 describes a gem that has just the tiniest inclusion, barely visible to the unaided eye of a trained, experienced grader.

Lightly Included 2 ( LI2) is similar but with one or two more inclusions, of the same minute size.

LI1/LI2 inclusions are so small that most people cannot see them without magnification, even after intense scrutiny of the gem.


Moderately Included 1 (MI1) inclusions are minor inclusions that don't affect beauty or durability. These inclusions are often not visible to the casual observer.

Moderately Included 2 (MI2) inclusions have a slight effect on appearance but do not affect brilliance. These inclusions are often not visible to the casual observer.

Inclusions in MI1/MI2 gems are so small that many people cannot see them without magnification.

 

Highly Included 1 (HI1) Inclusions are obvious and have a slight effect on appearance and brilliance.

Highly Included 2 (HI2) Inclusions are obvious and have a significant effect on appearance and brilliance.

 

Extremely Included 1 (EI1) Inclusions are prominent with significant effect on appearance, brilliance and transparency.

Extremely Included 2 (EI2) Inclusions are numerous and prominent throughout gem with severe effect on appearance, brilliance, transparency and durability.

Extremely Included 3 (EI3) Inclusions are numerous and prominent throughout gem. Gem is not transparent and shows no brilliance.

“If you are considering the purchase of a natural, untreated sapphire, then I suggest working with Bill Kent, the man behind www.sapphires.ca.

I was able to communicate to Bill what I was looking for and get his expert feedback. He allowed me to review and independently certify my stone selection prior to closing the deal.

Bill replied to my request for advice with detailed information that proved invaluable. This level of customer service is very rare these days.

And the stone is exceptional.”

How Do We Know These Are Untreated Sapphires?
Here's valuable information you.need from Canada's most experienced
gemologist/specialist in unheated,
.untreated sapphires:.

Heat treatment of sapphire.modifies the gem's internal structure.
Heat treatment also modifies.the natural variations.
in structure and composition.known as 'inclusions'..

Inclusions are modified in specific and predictable ways by heat treatment.
Inclusions modified by heat.treatment are visible with a gemological microscope.

.

A specific type of inclusion known as 'silk' is.diagnostic in the determination of sapphire.treatment/non-treatment..Silk consists.of a mineral.named 'rutile' which forms microscopically.thin.strands within sapphires..

Intact, unaltered silk within.a sapphire indicates.freedom from heat treatment..This photograph of very highly magnified silk shows.intact, undamaged silk..This is.the natural indicator of.untreatedsapphire..

.

 

My name is Bill Kent. My life's work has been grading,
evaluating and importing.precious gems..

Using a precise and reliable gemological microscope,...
I select untreated sapphires.that have only the smallest of inclusions.and I determine the untreated status.of sapphires.based on these very, very slight inclusions...


 

 

 

 

 

 

 


I'm a Graduate Gemologist comprehensively.trained in.Gem Identification.and.Gem Grading
by the Gemological.Institute of America,.with additional training in Gem and Jewelry Appraisal...

 

 

 

 


 









 

 

My training at The Asian Institute of Gemological.Sciences,.Bangkok,.Thailand included.Advanced.Techniques in determining Gem Treatments and Gem Identification.. I personally guarantee the. authenticity.and freedom. from.heat treatment of every. sapphire on this site..

 

In addition, each of these sapphires has been examined by highly trained, ..
experienced gemologists
in the.leading gemological laboratory in Sri Lanka. .
Precise and thorough examination.by highly-qualified gemological experts .
guarantees you'll receive a sapphire.free of heat-treatment.
.

Sri Lanka is the island-nation near the southern tip of India and is the world's .
primary producer of superior quality sapphires.. .
Sri Lankan origin of a sapphire doesn't indicate freedom from treatment.. .
Heat treatment of sapphires is now widespread in Sri Lanka. ..

 

Every sapphire on this site is a unique.creation of nature. Each gem on this site
contains its own, one-of-a-kind.pattern of.
natural, unaltered inclusions
.indicating freedom from treatment..

Each gem-description contains the phrase: 'Untreated sapphire as indicated by...'.
giving you information about each gem's inclusions...
Natural, unaltered inclusions are permanent indicators.of the untreated.
status of your sapphire. With proper magnification,.you can see for yourself!.

Unmodified, natural inclusions are indelible.hallmarks of natural, untreated sapphires!..

Your untreated sapphire has its own
unique internal pattern.that forever indicates its untreated status..

 

When examined under a gemological microscope, virtually every sapphire
will reveal some inclusions...

Very small (microscopic) inclusions have virtually no impact on the value
of coloured gems, including sapphires...

Large inclusions reduce value. My inventory of sapphires is free of large inclusions...

I select your untreated sapphire using rigorous gem clarity standards.
I select only sapphires of a very high degree of purity. .
so you'll enjoy the satisfaction..
of owning a rare and beautiful untreated sapphire of superior quality!...

   
For more information on Heat Treatment of Sapphires, please visit Frequently Asked Questions.
 

I make frequent trips to Sri Lanka to select sapphires at the mines. .
Here we're using an ancient technique for separating rough gems from muddy gravel.
excavated from the mines--the first step in the long journey.
your untreated sapphire travels to you. My hands-on approach saves you money!.

Actively selecting untreated sapphires at the mines .
lays the foundation for giving you the best value from the very beginning..

 
 
   

Proportion Grading Of Gemstones

   

Good proportions in gems are found when the crown angles and pavilion angles.
are within acceptable ranges, resulting in the pavilion (bottom)..
and the crown (top) of the stone being neither too deep nor too shallow...

Proportions are more important in diamond grading.
than in colored stone grading.
.

Excellent proportions are essential to the beauty of a diamond.
because proportions determine how light is reflected from the surface..
of the diamond and how light is refracted from within it...
The entire visual impact of a diamond is created..
by light rays reflected from its surface and refracted from within it..

In all colored stones (all gems other than diamonds),.color is a more important contributor
to the gem's beauty than proportions...


Each individual piece of sapphire 'rough' (the uncut, unpolished gem material as
it's found in the mine) has its own unique shape.

.
Some sapphire rough yields maximum weight if the pavilion is cut shallow.
and some yields the most weight if the pavilion is cut deep.
..

The cutter of sapphires saves as much weight from the rough .
sapphire crystal as possible while producing the most beautiful finished gem...
