[meteorite-list] Info on Polishing Cut Stones? ( AD ++ )

[BRIAN SCHROEDER]

Hello Chris
Yes, there is alot of Scientific detail in 
Polishing a Cut Stone.  Problem is , what type of stone ??
Sapphire, Quartz, Iolite, Tanzanite, etc.. All of 
these have different Hardnesses, Structural 
Properties, Alignment of Molecules, and a vast 
difference in the way they are handled, Cut and Polished...
There are several Books written on techniques, 
alignment, preparation and special handling of 
many of these Gemstones.. Not Rocket Science

Now when we get to Meteorites and Tektites, their 
is Very Little Information available on these 
when it comes to Cutting and Polishing these 
Materials into Finished Gemstones..
Experience is a wondrous thing..  The difference 
between a pile of gravel and a Finished Gem may 
stem from experimentation, experience and knowledge.
A Gemstone that is aesthetically pleasing, that 
will hold it's Final Polish and retain it's 
internal Strength is the desired result we all wish to achieve...

Some Gems may need to be submersed in a Liquid 
while cutting and Polishing, others need to be 
aligned properly to show color, some minerals 
have directional hardnesses and the X, Y & Z Axis 
may all have different hardnesses and hold a final polish differently.
Meteorites are Minerals, and most of them closely 
match minerals we already have here on earth. 
Recognizing that a Moldavite Polishes like Quartz 
, BUT shows the best colors when Sapphire Facet 
angles are used, and these angles change as the 
Gems Size increase are all part of getting a beautiful final result.
Orienting a mineral is also important when 
Cutting and Polishing, knowing how to " read " 
the Parent Piece and Aligning it properly on that 
First Cut can be the difference between $$ and ¢ 
¢ ..  I am sure many can attest to this..

Now when cutting a Campo iron meteorite and 
noting the fact that it cuts like Pyrite and 
polished like Chill Cast Iron goes along way in 
saving Time and Materials, as well as achieving the desired final results.
OR -you could just grab a piece of Fine Grit 
Sandpaper and place it on a sturdy , flat surface 
, moisten and polish for awhile and hope for the Best ??

RECOMMENDATIONS :
Send your material to me , and I will Cut, Facet, 
Cabochon, or Carve your materials for you at a 
Minimal Cost and return them to you.
I cut for many individual and commercial clients, 
Internationally,  and have excellent references. ( Mr. Reynolds ? )
Tektites in all forms are my specialty, BUT 
anything can be cut as long as it is Structurally 
Sound.    See Link    http://www.tektites.co.uk/SchroederB.html
Contact me to arrange a Trial Facet Job,  at a 
very Low Cost compared to having your materials 
Cut by Local Gem Cutters. Any and all Inquiries welcome.
Contact me directly if you are interested.      brian at aajewel.com

Send any questions you may have directly to me , to avoid clutter on the List..
Highest Regards
