quick draft

This is just a quick draft of what it could look like, feel free to edit --Doos 12:44, 1 February 2006 (PST)

Shouldn't availability also be part of the "what makes a gemstone" section? Africanuck, March 8

Yes that is a big part of it, but that is covered in "rarity". Although "availability" and "rarity" are usually the same factors, it may be artificial. Like the diamond cartel and probably also tanzanite. Furthermore politcs may play a role in this. For the most part this is not the case fortunatly. Feel free to define "rarity". --Doos 14:50, 8 March 2006 (PST)

Ok, I pulled out my FGA stuff, what they list is acceptability (not availability, you are right that is rarity, silly me) but don't list price as a criteria.... You probably know more than I, but some of the stones that are considered gemstones are pretty cheap, and I'm not too clear on how price enter into it other than as a reflection of it's desirability (often dictated by fashion) and availability?

One other question, is that supposed to be inorganic or organic? --Africanuck 06:51, 9 March 2006 (PST)

oops, organic ofcourse. You are right, let's drop "price". --Doos 07:16, 9 March 2006 (PST)

changed inorganic to organic and changed price to acceptability --Africanuck 07:35, 9 March 2006 (PST)

I'm also kind of wondering if "fashion" really fits in there... it's not really a criteria of whether or not a stone is a gem, and might be more appropriate to have it as part of the acceptability or rarity definitions. Or if we are going to touch on the subject of value, it might be added there. What do you think? --Africanuck 11:08, 10 March 2006 (PST)

Well fashion is a factor for much of the lower end gemstones (and at times for higher ends). If you look at the early 19th century you will find that lava stone was used widely in jewelry. Although we don't regard lava stone anything more than a curiousity in antique jewelry (studies showed that many of it was mere cement), it was used extensive in jewelry then (mainly due to the excavations of Pompeii and Herculanium). Painite is a new craze and might well be incorperated more a more into jewelry, also transforming it from a mineral into a gem. Ammolite is another example, it hardly passes the durability/rarity test. Yet many people seem to like it. So fashion plays a role. It's a thin line, a very thin one in many cases. --Doos 12:27, 10 March 2006 (PST)
Maybe acceptability/fashion .. I could feel comfortable with that. --Doos 12:32, 10 March 2006 (PST)
  • Antoinette Matlins uses the term "cachet" to describe the attraction that some gemstones convey in terms of "fashion." Tom Goodwin, G.G. 18:39, 14 February 2007 (PST)
My understanding of "cachet" has a "classy" factor in it. --Doos 10:45, 15 February 2007 (PST)
Classy is a very good way to describe it Doos. As in a padparadscha sapphire with vivid saturation, perhaps? Tom Goodwin, G.G. 20:37, 17 February 2007 (PST)


Africa edited the Gem-A section and I tested the rollback .. so I needed to put her edits back by hand. Use 'rollback' with care so it seems.

AIGS section

In the AIGS section, the following paragraphs are confusing to me. Any help on this?

"The A.G. (Accredited Gemologist ) Diploma :

The A.G. program includes the 4 core courses: E102: Gem Identification, E103: Diamond Grading and Pricing, E201: Colored Stone Grading and Pricing, E301: Synthetic and Treated Gem Identification.

These 4 courses can be studied in any order, in one or several study periods at AIGS. It is recommended that “Gem Identification” be studied before “Synthethics and Treated Gems”. "

also, i think CGA should be added to educational institutes.

I can read it alright, but if it's confusing for you, then probably to others aswell.Is it the numbers that make it hard to read (eg. E102 etc)? I added the cga.--Doos 06:33, 28 February 2006 (PST)

thanks for the CGA, doos. what confuses me about AIGS is the first line with the colon -- what does that refer to? to the following paragraphs? i see now that the last two really do link up fine (the paragraphing confused me but now i see it is ok). it is the first line that seems to be hanging in the wind, to me anyway.

I think that refers to the module codes of the courses. I didn't write that part so I dont really know. Rewrite it if you think that could be clearer.

ok, did. check it out to see if i botched it.


under career opps, what is a "tellsell company"? Gemma 20:35, 2 November 2006 (PST)

maybe that should read "telsell"? .. like JTV --Doos 07:13, 3 November 2006 (PST)

that makes sense, thanks Gemma 16:53, 3 November 2006 (PST)

spell checked and edited Gemma 20:19, 6 November 2006 (PST)

Definition of Gemologist

A lot of people (like rockhounds) study gem minerals. Does that make them academically trained? When I think of anyone who is a "ologist" I think of formal academic training and achievement to attain such a title. In my opinion, because of this, the definition of "gemologist" needs to be edited and expanded here reflecting the professional full time work and dedication involved. I know a lot of amateur "gemologists" who couldn't separate glass from diamond. NO JOKE! Tom Goodwin, G.G. 17:32, 14 February 2007 (PST)
