Talk:Tourmaline

message: The Refractive Index entry is incorrect, transparency is ANOTHER optical property. The correct Refractive Index for Tourmaline is 1.624-1.644. The variation is +-.005 and the birifringence is .020.
:OK. Fixed per 20th ed. Dana Manual. The article text appears to be largely from 1911 Britannica article and in need of serious rewriting ... someday :-) -Vsmith 00:11, 29 Apr 2005 (UTC)
thread_title:  Incorrect entry of Tourmaline Refractive Index 

message: The whole page is wrong. 'Tourmaline' is not a mineral, and shouldn't be described as one. It's a group of minerals with similar (but not identical) properties - minerals such as Elbaite, Dravite, Schorl, Uvite, etc.  So it's plain wrong to list physical properties, etc. when they vary from species to species. I don't really have time to update this now, but someone needs to kick this page around. --Jolyonralph 13:09, 6 May 2005 (UTC)
replies: text: I agree w/ Jolyonralph, tourmaline is a group of minerals with varying compositions. Many of the physical properties are shared by members of the group but not all. The page should be revised as a group page with each of the various minerals in the group described with a section or a separate page (for the major ones). Properties in common should be discussed in the intro and specific properties amplified in each section/subarticle. See Mineral galleries] for an example discussion. I'll put it on my to do list, but ... when?  :-) Vsmith 04:05, 15 Jun 2005 (UTC)

thread_title:  Wrong! 

message: i have this piece of tourmaline,approx. 1" diam. x 2" long, basicalliy a 2"x 2" cylinder.
it looks pretty dark ( opaque ) looking down the axis,has blue/green/golds on the edges and has a rough "skin" that is white streaked and rough,almost as if it was a stalag-mite/tite. i got this in a little "mine your own" type place in the White Mountains of New England.Namely just off of Mt.Washington in New Hampshire/Vermont.
Can anyone advise me of this crystal?
thank you

message: It should probably be noted that while the different species of tourmaline are commonly divided out by their color this is not an accurate method of distinction by any means.  Along those same lines this article refers to both the species and the variety names but does not at any point make the distinction between the two, that species are recognized minerals and varieties are just general names with no regulation as to meaning Kevmin 02:08, 26 February 2007 (UTC)
replies: text: The "varieties" that you reference, Dravite, liddicoatite, elbaite, etc... are not in actual fact varieties.  These are separate SPECIES of minerals that are part of the Tourmaline GROUP, which in turn is not actually a mineral species itself.  THe spereation of tourmaline by color is at best inaccurate.  The color that a specimen my be often has little bearing as to the actual species represented. This is one of the inconsistencies that I was referring to in my original post, PS please sign your posts  Kevmin 02:02, 6 March 2007 (UTC)
replies: text: You are both speaking different languages. Kevmin, you speak mineralese, while Krementz speaks gemstone-ese - to use this rough analogy. In your own fields you might be correct but to foist your respective views on the article would be short sighted. Right now the article needs a bunch of expansion to tease out the intracacies of this gem/mineral group. As with any mineral/gem I would suggest developing subsections to deal with the different content needed to develop the article. Mineral details specifying species of tourmaline etc, and then a seperate section dealing with the gem varieties (that are typically based on color - ignoring the mineral species), rubellite, indicolite, paraiba, bicolor, etc. BTW I would like to confirm whether the statement made by Krementz that "almost all the jewelry-usable material is elbaite" really is accurate. I am not sure that it is. Prove me wrong though please. SauliH 07:28, 6 March 2007 (UTC)
thread_title: Varieties

message: Tourmaline as a solution is used to antique or darken copper, brass and bronze. It is available in brown and black and afterwards the metal should be rinsed in water before coating with Jade Oil. It would be interesting to know the chemical composition and process required to produce the Tourmaline fluid.

message: Anyone feel like dealing with the emergence of an impression amongst the ignorant that Rubellite is a kind of artificial ruby ?   Maybe this is because of the common heat-treatment technique ? 86.141.92.73 21:42, 11 June 2007 (UTC)

message: There are now patches TRMX-2i that the Chinese have developed to detoxify the body. They are made with 60% Tourmaline and "emits negative ions on average of 1300 ion/cm3.

message: The end member formulas do not reflect the general formula.  It seems to me the general formula should at least have a Si6
XY3Z6T6Si6O18(BO3)3V3W
I don't know if the rest of it is best represented perhaps it should be 
X Y Z Si6O18...
Where some of XYZ are polyatomic ions and can also be vacant. Hwttdz (talk) 06:02, 8 January 2008 (UTC)

message: In the first paragraph, << "Thuramali" (තුරමලි) or "Thoramalli" (තෝරමල්ලි) >>, the bits in brackets just appear as blocks.  I'm running Opera 11 on WinXP x64, which I know is an uncommon configuration, however I was wondering whether other users also have this problem.
Somebody pasted those bracketed names in (or edited that paragraph) on a browser/OS that doesn't fully support wiki's charset/encoding.

message: I appreciate the scientific information on Tourmaline.  But I would also appreciate a scientific evaluation of health claims by companies selling equipment with various claims.  I think esoteric effects can be ruled out as subjective.  But most of the links in Google have to do with health claims.  So if WP could include a section on that (quackery or benefits) that would be helpful.  Thanks ññññ Peter Stucky  — Preceding unsigned comment added by 181.142.226.245 (talk) 20:31, 21 May 2016 (UTC)
