Guest guest Posted October 14, 2005 Report Share Posted October 14, 2005 > 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 Best rgds, Richard Quote Link to comment Share on other sites More sharing options...

Guest guest Posted October 14, 2005 Report Share Posted October 14, 2005 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, Chandrashekhar PhadkeRichard Shaw Brown <rsbj66 > wrote: > Respected Shri. Richard ji, What are 'Jyotish Quality Gems and Precious Stones ?'
