message: A new reference about crystal should also include the word as slang for methamphetamine.
Methamphetamine? That drug is a crystal of a specific substance that does not shed light on the general solid-state concept. Put it in crystal (disambiguation). That is the place for slang terms, this article is about the technical term 24.184.234.24 (talk) 00:17, 8 October 2009 (UTC)

message: I added these references not because I believe in crystals but because the word "crystals" is used often by people conversationally (and also is referenced in various Wikipedia articles) to refer to the belief system itself.  I would suggest leaving it because the word 'crystals' has these 2 meanings and even though this is a scientific article, you can't just remove the meaning from the word.

replies: text: This is all covered in the Charmstone article, or if it's not, it can be added there, and there's a disambig page already to direct the reader to that usage of crystal, so I reverted your edits as being inappropriate for this particular article on crystals.

replies: text:  Alright but the disambig is only there because I added it.  I have gone into several articles referencing crystals and changed the reference to crystals to avoid confusion.  Thanks, laurap414 00:26, 8 August 2007 (UTC)

thread_title: Reference to Charmstone and New Age

message: Some one cited the fact that most metals encountered in daily life are polycrystalline. What the statement means is that metals have a grain structure. You can find this under the linked article for polycrystals, which the author was careful to link. The problem with this request for a cite is that the grain structure of metals is just about the first and most fundamental fact of metallurgy. It is like requesting a cite on the letter a if someone starts to recite the alphabet. All naturally occurring metals have a grain structure and you don't need a special note for that. True it needs to be mentioned somewhere but that is taken care of (with special note) under polycrystal. Thanks.Dave (talk) 12:43, 20 April 2008 (UTC)
thread_title: Removal of "cite" tag for metallic polycrystals

message: There is a link here to a site published by Bob's Rock Shop. I pondered whether this is to be considered primarily advertising. The owners however are genuine scientists using Bob's Rock Shop to publish scientific educational material under a separate heading. This is a tough call. Some advertising in this case is inadvertent. I decided to leave it in because the scientific material itself does not talk about Bob's Rock Shop. If this were a site from some university the university would be mentioned so in this case whether the publisher is profit or non-profit is only incidental. The topic is certainly open to discussion. Thanks.Dave (talk) 13:10, 20 April 2008 (UTC)
replies: text: Similarly Krassmann's site contains links leading to a catalogue of his collection, which he will sell or trade. But, the scientific part is kept apart, so if I am leaving in Bob it seems fair to leave in Thomas. To separate advertising from source material is sometimes difficult and I think I have been pretty good about excising blatent sales material - the prices of papers, Amazon or other bookseller sites, porn sites who will sell you heaven knows what, authors peddling their books, businesses using their community's Wikipedia article, what have you. But if a scientist happens to use a private site to publish scientific material - well, it's on the line I think.Dave (talk) 14:45, 20 April 2008 (UTC)

Also, I agree that this very important article should totally undergo a major refinement and a big increase in content and thus in length as well. Currently, the
featured information isn't sufficient, e.g. more photos and chemical diagrams should be added. Ve4ernik (talk) 23:21, 14 January 2009 (UTC)

message: Who said a non-polar crystal is a conductor? (sic) For instance of an |elemental crystals such as sulfur is generally dielectric. A non-metal the Wikipedia article says is a "poor conductor of heat and electricity compared to metals" If you mean crystals composed of metal atoms it takes a separate entry.

message: The largest crystal cave`s can be more than 11 meters (36 feet) that may not seem large but the caves are realy masive geodes (holes in the middle of most crystals).People naturaly want to explore these strange enviroments but there are limatations the humidaty in these crystal caves are to high for humans and most other animals to survive for long. the humidaty levels to be presice are round about 100% and the tempreture is round about 65 degrease celsius (150 degrease farenhight).the crystals themself feed on the humidaty to grow verry slowly they would disintagreat without it they are gypsum crystals.  — Preceding unsigned comment added by Gamma45 (talk • contribs) 19:48, 26 January 2012 (UTC)

message: I did a grammar and punctuation cleanup, primarily on the Occurence in nature section. I'm not an expert on the subject. Large sections of the article have no or minimal inline citations, so I added the refimprove tag. ~ Kimelea (talk) 17:12, 28 January 2012 (UTC)

replies: text: Do you have a specific content question? There is no requirement for a humanities reference style in Wikipedia articles. That said, this article doesn't have any style ... it just sorta evolved. As noted at the top it needs additional citations as much unsourced material remains from early versions of the page. Sorry 'bout that and hope you survive your desperation... Vsmith (talk) 21:00, 7 March 2015 (UTC)
thread_title: Citation style

message: From the paragraph below, I suggest removing the word "pseudoscientific" as it is not relevant to a practice of alternative therapy.  Also suggest removing reference to "Wiccan beliefs".  Wiccan use of crystals are a small part of crystal usage so should not be highlighted. This article is mainly about the science of crystals, so not relevant.  Also remove reference to "spellwork" as again, it is not how most people use crystals. 
Crystals are often used in pseudoscientific practices such as crystal therapy, and, along with gemstones, are sometimes associated with spellwork in Wiccan beliefs and related religious movements.[6][7][8] Dianej1111 (talk) 13:57, 19 December 2017 (UTC)
replies: text: . Our article on crystal therapy is called crystal healing, the term "pseudoscientific" is used there, and it's reliably sourced. We're aware that this can be contentious or hurtful but that doesn't make it any less true. Crystals' minor status in Wicca appears to be covered by the word "sometimes." As for the use of "spellwork," please see the third source here. This page doesn't use that word but it still verifies this. City</span>]]OfSilver 21:42, 19 December 2017 (UTC)
