WHY? and HOW? (GEM CLARITY)

[Guest guest]

> Respected Shri. Richard ji, What are 'Jyotish Quality Gems and Precious Stones

?' How do

they differ from the normal gems ? What are the basic characters of Jyotish

Quality

stones?

 

Sri Chandrashekhar Phadke,

 

Namaste!!! Good to hear from you. And an important question. In fact the subject

of

exactly how to judge the goodness or badness or even falseness of a supposed gem

is a

big science called Gemology. And it takes years to be able to identify any

supposed gem

as to what it is, and years more to judge quality.

 

If an unknown green stone-looking "thing" is given to a gemologist then he

begins the

process of alimination, it's NOT this, it's NOT that, so it must be "beryl". And

green beryl is

called as a gem, Emerald, when it is transparent. If it's opaque then it cannot

be called as

emerald (even if green color) because emerald is the elite variety of GREEN

BERYL that is a

clear crystal. The lower qualities are "industral" quality or "bluff stones".

 

So what to speak of quality, a layman looks at a green stone and has no idea

what it even

is. Therefore the need of gemologists, just like doctors. Otherwise a piece of

green glass

or a synthetic can be passed off as genuine. And foolish people actually use

such bogus

things and think that is "Planetary Gemology".

 

The only thing that is in the favor of synthetics or glass is that they are NOT

harmful.

Likewise they are NOT useful. They are an illusion. But after all they are

harmless.

 

That is not the case with genuine natural gems. And a gem is, by deffiniitation,

a naturally

occuring object. In case of genuine gem there are four considerations. Called

the 4 Cs.

viz., COLOR, CUT, CARAT WEIGHT & CLARITY...

 

Color is a description of the primary hue of a gem when viewed in indirect

sunlight.

 

Cut describes the external shape and style of a gem's cutting and polishing.

 

Carat is weight of the gem (1 gm = 5 carats).

 

Clarity describes the extent to which a gem is free of flaws when viewed through

10x

magnification (10x loupe) in dark field illumination. The clarity grade for

"Jyotish quality"

is expressed as a percentage of purity on a scale from 100% clean (0% flawed) to

0% clean

(100% flawed).

 

100% flawed means an industrial ROCK. Totally useless for Jyotish, but more than

useless

it is deemed HARMFUL for human use.

 

This it is stated about emeralds from Sri Garuda Puranam:

(excerpt: "Ancient Indian gemologists have given the highest praise to emerald

possessing the following qualities: display a rich, even color; emit a soft

glow; appear to

glisten with gold dust inside; devoid of any serious internal or external

blemishes. the gem

also should be properly cut so that maximum light is refracted to the eye of one

viewing it

face up."

 

"Emeralds considered inauspicious are blackish, devoid of luster, appearing

dirty inside or

dried and brittle. Anyone concerned with their own well-being should never

purchase or

wear any oiled, dyed, or treated emerald. Also, emeralds of mixed colors are

strictly

forbidden."

 

---To simplify matter, lets take an example... You shine a penlight through an

emerald,

and it is crystal clear with no visable flaws... so lets call that one

"healthy". And in case

you see small minor flaws, like 20%, then that is "diseased" And if you see

totally flawed

then that one is "dead" --- just like you would be if your body had that much %

of flaws.

 

If you can see 15-20% visable flaws with the naked eye then, when viewed under

10x

magnification it will be "heavily flawed". And the clarity grading is done using

10x loupe or

scope.

 

The safe clarity range is "eye clean" to "loupe clean" (when the stone is viewed

with a

penlight shining through. If the light won't even pass through, then it is like

a "brick."

 

As Shastra says so many times about "clarity' or quality, so we know that is a

must. Any

so-called testing done using bad quality stones is deemed as bad research.

 

I hope this helps

Thank you very much for your mail. You have explained the subject thoroughly

but in simple words, as if I am in a study class and hearing a lecture of my

Professor explaining complicated subject matter in more simple words.

 

Sir, are you planning to write any book on Gemology ? I feel, it is necessary

to compile your knowledge and experience in a book form for future generation.

 

Thanking you and with personal regards,
