I have added some historical notes and more cross-references making it clear that moissanite is both (A) synthetic, if purchased as a gemstone, and (B) the same material as SiC/carborundum. The article probably still needs work, but it reads less like advertising copy now. Some particularly vague comparisons have been discarded -- for example "about one tenth the price per carat of diamond" doesn't actually mean anything useful since the price per carat of diamond varies by a factor of over 1,000 (for powdered industrial diamond grit vs. a 2-carat blue-white brilliant cut VS). zowie 16:48, 12 May 2005 (UTC)[reply]

Cost?

Does anyone have any specific figures on the rough cost of this simulant for various caret weights? Say in 2005 USD? I'm just curious. Deco 06:46, 9 August 2005 (UTC)[reply]

This page lists prices for round-cut moissanite at a particular retailer.

I have purchased many Moissanite items from this retailer. ∞☼Geaugagrrl^(T)/_(C) 17:16, 8 March 2008 (UTC)[reply]

Here is a good source of information for Moissanite:[1]

This article was prepared by Mareah Flynn for the University of Houston course GEOL 3370 introduction to Mineralogy, Prof. Jonathan Snow, Instructor.

Duplicate, badly formatted

Given that this article needs wikification and cites vaguely-relevant journal articles, I suggest that the useful content be merged into the Silicon_carbide article and a redirect be put into place. Bandy (talk) 02:08, 30 January 2008 (UTC)[reply]

I agree! The article on SC seems more mature, and is more informative. EvertW

Criticism of Diamonds

It also might be worth noting that consumers choosing moissanite, are not participating in any kind of "blood diamond" stuff. 208.107.220.11 (talk) 14:22, 4 May 2008 (UTC)[reply]

Just found this link: http://diamondnexuslabs.com/jewelry/newsdesk_info.php?newsPath=1&newsdesk_id=5&gclid=CLz3oJGGjZMCFQx7PAod9winng 208.107.220.11 (talk) 14:26, 4 May 2008 (UTC)[reply]

Instead of being a diamond stimulant, Moissanite stands at its own because of its beauty. People are looking for something better than just diamond. It's unfair to say that it's a substite of diamond, it's a misunderstanding of Mossanite its own, since nature Moissanites are more rare and expensive than diamond. —Preceding unsigned comment added by 24.148.129.238 (talk) 17:53, 24 August 2008 (UTC)[reply]

I just took out misleading references to "diamond simulants", which imply the driving desire behind selecting moissanite is cost reduction. —Preceding unsigned comment added by 70.91.1.201 (talk) 18:22, 27 September 2010 (UTC)[reply]

Rhenium diboride, hardness or lack of same?

The wikipedia article on superhard materials states that rhenium diboride used to be considered harder than diamond, but in reality is not. Songflower (talk) 19:50, 26 April 2009 (UTC)[reply]

Patent expiration

Does the patent for production of this gem expire on aug 12, 2011? — Preceding unsigned comment added by 24.208.24.227 (talk) 03:36, 11 August 2011 (UTC)[reply]

Pronunciation of Moissanite

When Moissan descendants lived in Canada, they pronounced their name Mwah-sohn. So since the gem is named for that inventor, it seems that the French pronunciation would have to follow. Mwahsohnite? — Preceding unsigned comment added by 50.105.24.57 (talk) 15:23, 23 August 2011 (UTC)[reply]

Simulant

I pulled the statement about moissanite not being a diamond simulant. It was unsourced and with a quick google search I found no consensus. I may be wrong but to me it sounds like an opinion statement, or something situational. It might be worthy of a paragraph of why/why not, if someone would be willing to do some digging and source it.--Ccyyrree (talk) 23:07, 24 October 2012 (UTC)[reply]

Electrical Conductivity of SiC

The article states that one way to tell the difference between SiC and diamond is its electrical conductivity as they both have similar thermal conductivity. So does SiC have higher or lower electrical conductivity compared to diamond? I think that that is a critical facts that should be included in the article.==BeeCIer — Preceding unsigned comment added by 207.81.0.235 (talk) 09:16, 24 September 2014 (UTC)[reply]

Higher. Tweaked that in the article, thanks. Materialscientist (talk) 09:34, 24 September 2014 (UTC)[reply]

Thermal conductivity of 6H-SiC

I was doing some googling the other day and found that the thermal conductivity of Moissanite was not seemingly readily available in a format parsed for the average person.

I'm not sure if I just missed it, but I couldn't find any data about thermal conductivity in the reference (footnote #15) this wikipedia article used when it mentioned a similar thermal conductivity to diamond.

After a few hours of research, I found these sources: https://iopscience.iop.org/article/10.1088/1757-899X/848/1/012066/pdf http://www.mtixtl.com/xtlflyers/SiC.pdf

I know little to nothing about finding scientific sources or reading papers, so I don't know if these are acceptable sources, but they claim a thermal conductivity of around 5w/cm k. I think this is important information to put in the Wikipedia article because when you search on google, the very first result is misinformation: A sponsored article on a news site claiming moissanites thermal conductivity is "25% greater than diamonds"

Given that I don't know much about checking sources, and I'm not quite sure how to add this information to the article, I figured it was wiser to make a post about this than to try to improve the article myself and ending up making it worse BismuthRose (talk) 22:17, 26 September 2023 (UTC)[reply]

Correction: The thermal conductivity is 5w/cm k at 300k (room temperature) BismuthRose (talk) 22:19, 26 September 2023 (UTC)[reply]

I actually just realized that thermal conductivity for 6H-SiC is mentioned on the main page for SiC, but I still think putting this information in the Moissanite article is important to fight misinformation. BismuthRose (talk) 22:32, 26 September 2023 (UTC)[reply]
