Jade in China?

There definitely needs to be some expansion here on the significance and massive history of Jade in China.

That's virtually a whole article unto itself.....but yes, more content on the meaning and crafting and history of jade in Chinese culture would certainly be worthwhile in this article, but likewise in Andean and Meso-American cultures; it's important also in the history of mining in British Columbia (in no small part because of the Chinese, in fact...).

There is an article Chinese jade actually what would be better would be to move relevant details to that article.KTo288 (talk) 10:33, 17 November 2008 (UTC)

I would like to add a great deal more to this page on Jade. I am a geologist and I have studied jade for more than forty years when I collected my first pre-Colombian jade artifacts in Costa Rica. I do not know how to manipulate wikipedia well enough yet to make changes. My wesite is www.shunyadragon.com/ Anyone who wants may take a look for ideas to improve this page.

I noticed one misleading statement in the text. It said, 'Jade has a hardness of 6.5 to 7.0. Jadeite has a hardness of about this range 6.5 to 7.0. The Actinolite-Tremolite series that makes up the compact microcrystaline Nephrite has a hardness of 5.0 to 6.0. Some nephrite from Kunlun Mountain is reported to have a hardness of about 6.5. —Preceding unsigned comment added by Shunyadragon (talk • contribs) 23:30, 18 January 2009 (UTC)

There are numerous problems with the jade page. The main problem is it reflects a layman's view and lacks good technical references. I changed the mineral names and the hardness reference to nephrite and jadeite as well as a spelling error. The website reference to hardness no longer works and is in error. The reference 3 needs to be changed to - Klein, Cornelis and Cornelius S. Hurlbut, Jr. Manual of Mineralogy (after J. D. Dana), 21st edition. 1993. Jon Wiley & Sons, Inc. New York. I do not know how to correctly make these changes yet. See my web page at www.shunyadragon.com for more information concerning how I would like to update and correct Jade page. —Preceding unsigned comment added by Shunyadragon (talk • contribs) 17:00, 21 January 2009 (UTC)

You are correct. There are many problems with this page. For starters, both of the jades are actually rocks, not mineral species. Thus the box on the right describing the properties should be removed. Each rock has different properties. Rubydick (talk) 05:43, 5 December 2023 (UTC)

Link to Jade Bay?

Should there be a link to Jadebusen on this page? I was looking for information about the Jade Bay, but couldn't find it until I found an entry in Encyclopedia Britannica with Google, which gave the German name, which I then managed to find in Wikipedia. A bit awkward...

The term "Jadebusen" is not related to the Mineral. The name comes from a town and a river nearby. Just coincidence. --84.159.154.91 20:15, 7 March 2006 (UTC)

Does any one know if Jade or a Jade like material glows in the dark?

I have a Chinese dragon statue that is a light green such as the picture on the page showing about Jade, but at night when all lights are turned off it glows. It appears to be made of some type of stone as it is very heavy for its size, and the only stone I could think of in this color was Jade. However, I don't know how to find out if it really is Jade. Any help will be appreciated. Contact me at Kristie_Palmer_Warner2003@yahoo.com thanks.

Many minerals will glow when exposed to ultraviolet light. Some minerals glow when heated a little. Google around a little.

Wikipedia (as of Oct 2024) isn't a Q&A forum. I assume this post is old and the poster young. Now-a-days, your typical search engine, Google, Bing, DuckDuckGo, etc. etc. will probably answer the question. Short answer is:"No, probably not." (But it's very possible to treat jade to make it phosphoresce. (Phosphoresce = Glow in the dark, (and without UV lights (or x-rays, gamma rays, or heat).) I simply don't know if such treatments are common or unusual or rare. (terminology-wise, luminescence includes both fluorescence and phosphorescence. The difference between fluor. and phophor. is the average time (decay half-life) it takes for the excited state to return to it's normal (ground) state. Fluorescence occurs typically in micro- or milli- seconds and phosphorescence can occur over seconds, minutes and even hours. Treatments include doping, staining, coating, and irradiation.

sections and subsections

There is a history section in this article in which greenstone and jade use in ancient China, Korea, and New Zealand are briefly introduced. The aforementioned are arranged as subsections. Why then, does the history of jade use in Mesoamerica have its own full fledged section, when it actually contains very similar material to what is found in the history section? I think the Mesomerican section should become a subsection along with the others and should be found within the History section instead of apart from it. What do you think? -- Mumun 無文 15:55, 4 April 2007 (UTC)

-returned Mesoamerica to status as part of History section. -- Mumun 無文 18:39, 11 April 2007 (UTC)

Are they Jade??

I have two items that appear to be oriental tiger/dragon statues from an estate. They are very consistent in their light green color, although not exactly the same shade each. They are only 6" tall and 3-4" wide, yet weigh approx. 7 lbs each! I was told they were Jade and they are very delicately crafted with great detail. I do not see any veins of discoloration in either one. I wonder if they are truly Jade and what their potential worth would be...any help out there?? Thanks so much. ps...they are foo dogs, still not sure if they are jade though...help? —The preceding unsigned comment was added by 216.64.58.146 (talk) 11:25, August 23, 2007 (UTC)

pretty useless without a picture to see what the stone looks like, but even so a gemologist or jeweller is gonna have to make the call; soapstone can look like jade, as can other minerals. If they're Chinese-style dogs, though, they're probably jade....Skookum1 (talk) 02:31, 15 November 2008 (UTC)

Faux Jade

In the section "Faux Jade" shouldn't the paragraph about the Chinese characters be either moved to another section or in its own? I think its out of place.--24.193.175.4 (talk) 14:46, 25 November 2007 (UTC)

Machine translation?

The following section:

"Hetian jade and gems of the Chinese nation, is China's "National Stone." And distributed in Xinjiang's Hetian jade Shache - Kashikuer dry, Hotan - in Hetian, Qiemo County, stretching 1,500 km north slope of the Kunlun Mountains, a total of nine origin. And the mineral composition of Hetian jade to tremolite - from stone-based and micro-diopside, serpentine, graphite, magnets, and other minerals, a white, blue green, black, and so different colour. Most of the monochrome-yu, a handful of variegated, for the translucent quality jade, after finishing a fat-like luster."

looks like a poor Chinese to English machine translation. Either it should be deleted or someone will volunteer to fix it. Avihu (talk) 14:18, 25 October 2008 (UTC)

Agreed and removed. Vsmith (talk) 14:37, 25 October 2008 (UTC)

Maw Sit Sit

Among the jades to come out of Burma, Maw Sit Sit (named for the town where it is mined) is one of the most prized for its dark green lustrous character. I think it might merit a mention here amongst other names. 210.50.190.28 (talk) 04:59, 12 December 2008 (UTC) Ian Ison

The village is actually called "Maw Sit." Not sure why the gem was called maw sit sit. Rubydick (talk) 05:45, 5 December 2023 (UTC)

Discrepancy?

Quoting lead:

Nephrite and jadeite were used from prehistoric periods for hardstone carving. Jadeite has about the same hardness as quartz, while 'nephrite is somewhat softer'. Both nephrite and jadeite are tough, but nephrite is tougher than jadeite.

i know close to nothing about mineralogy but i guess hardness and toughness must be two different mineral properties yet i feel that this passage is contradictory. Could someone with more knowledge about mineralogy take a look at the lead and fix it, maybe remove the possible redundancy Eli+ 22:39, 24 December 2009 (UTC)

The quote is plain wrong. As indicated in the section on Chinese vocabulary nephrite is "soft jade" and jadeite is "hard jade". There will be plenty of internet sources to describe this because of the stone's cutting anf carving popularityLuke Kindred (talk) 14:21, 17 December 2018 (UTC).

Color Changing?

My 9 year old daughter just received a white bracelet from her Chinese friend. It was a gift from the girl's Aunt in China, but it was too small for her wrist. It's oval, came in a nice box and she was told it was Jade, but you have to wear it for a month for it to turn green. I was doubtful, but here I am trying to find out, as some sites reference such an occurance. http://jade.yingyujade.com/

Enhancement section?

The Oct. 28 edit in the enhancement section appears to be both machine translated and possibly inaccurate. I have not been able to verify the new information through a fast search, although admittedly I was not looking very strenuously. Also, the two new sections appear to have very little to do with jadeite/nephrite enhancement and instead are about the various qualities and classifications of jade. At the very least, the English should be cleaned up if the information is verifiable. —Preceding unsigned comment added by 128.12.214.69 (talk) 08:18, 4 November 2010 (UTC)

Removed. Vsmith (talk) 10:49, 4 November 2010 (UTC)

This does not belong in the actual article, but does anybody take jade that is near white jade in quality melt it to liquid and then do what is called zone refining to move all the iron and impurities at one side, At $3000/oz there is an opportunity for a new kind of white jade or whiter jade. Also if jade is liquified perhaps it can be prestressed to add even more strength and molded into high utility, beautiful, and valued shapes Treonsverdery (talk) 09:50, 14 March 2022 (UTC)

Assessment comment

The comment(s) below were originally left at Talk:Jade/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.

This article should now be trimmed that the Nephrite article is in place. The purpose of the Jade article should be to discuss anything that the two Jade forms have in common. Specific information about each form should be moved to their respective articles. SauliH 06:37, 28 January 2007 (UTC)

Maori

Trying to avoid an edit war, but the valuable information recently added in the para that began: "Maori lore is replete the spiritual aspects of pounamu..." is implied to come from Pollard. However, a search via Google Books[1] shows that it doesn't - and a more general Google search finds no reference these various assertions elsewhere. Māori_music#Waiata ''Waiata'' for example is just the word for song or chant.

If I'm mistaken, (always possible), please feel free to re-add it - but only if you can insert refs for each item, and to specific pages in the case of Pollard. - Snori (talk) 08:49, 12 February 2018 (UTC)

Jade vs. Nephrite

I'm baffled that there isn't more history and info on the value and rarity and demand for jade creating a demand for and the eventual legitimization of nephrite as a sculpting and lapidary grade gemstone.

How is the article for nephrite polished and this one doesn't even have an infobox yet? Has this edit war compromised the article entirely? Adding to my work list.Luke Kindred (talk) 14:41, 17 December 2018 (UTC)
