Talk:Jet (gemstone)

Lignite?
why was lignite used as a jewellery item? It thought it's pretty common... And is it more known today as 'jet'? Because i've always known it as 'lignite' or 'brown coal'...


 * Is there some mistake here? I'm no geologist but jet is clearly not the same as the brown coal that the word "lignite" normally refers to and I can't find anything to confirm the idea that jet is also known as lignite. Flapdragon 23:29, 27 July 2007 (UTC)


 * Jet is a form of lignite, but it's harder than the lignite used as fuel and takes a polish which the fuel doesn't.MidlandLinda (talk) 21:24, 1 March 2010 (UTC)

Jet black?
Is this the source of the expression "jet black"? Cctoide 11:58, 8 May 2007 (UTC)


 * That seems very plausible, and this seems to bear that out. Some corroboration probably ought to be found, and the information included in both this entry, as well as any future entry about the color. --Belg4mit 19:39, 8 May 2007 (UTC)


 * Chaucer, in the "Nun's Priest's Tale" says "His Comb was redder than the fine coral..His bile was black and as the jet" That's c1386, and the OED says it's the stone that's the source of the saying.  MidlandLinda (talk) 21:31, 1 March 2010 (UTC)

Yes, I have been told that is where the expression comes from. I went to school for metalsmithing and jewelry and I learned this in my history of ornamentation class. — Preceding unsigned comment added by 76.179.220.63 (talk) 01:38, 23 October 2011 (UTC)

Wrong picture

 * there is no jet visible on the second picture, all I see is bronze:

Someone maybe want to edit it? — Preceding unsigned comment added by 37.24.112.226 (talk) 20:38, 13 February 2013 (UTC)

"Damselfly" versus Dasselfliege
"Damselfly" is a misreading of German Dasselfliege, meaning "botfly". See images of botfly-larva jet-carving at Venus figures from Petersfels. MagistraMundi (talk) 08:53, 9 August 2016 (UTC)

Jet is not lignite
Jet is not a type of lignite. Jet is a drift wood fragment incorporated in sediments which is compacted and impregnated by bitumen during diagenesis. Jet occurs in oil shale formations. Jet is not visible on the first picture. This picture shows a piece of oil shale with clearly visible stratification.22.11.2016. — Preceding unsigned comment added by 134.2.216.181 (talk) 15:15, 22 November 2016 (UTC)


 * Do you have any reliable sources, preferably with web links, that support your statement that jet is not a type of lignite?
 * Here are a few sources that state that jet is a type of lignite:

Terminology
The term for the style of early jet necklaces is apparently spacer-plate necklace

Removed section
I can't find a source for this and a passing mention of 20s fashion in a history of whitby jet says they weren't able to capitalise on the fashion for black jewellery suggesting any such necklaces would have been made of other materials.©Geni (talk) 12:21, 3 February 2021 (UTC)

20th century
In the United States, long necklaces of jet beads were popular during the Roaring Twenties, when women and young flappers would wear strands of jet beads stretching from the neckline to the waistline. In these necklaces, the jet was strung using heavy cotton thread; small knots were made on either side of each bead to keep the beads spaced evenly, much in the same way that fine pearl necklaces are made.

Upcoming PHd thesis
Sarah Caldwell Steele who is doing a PHd at durham is apparently working on a new method of identifying whitey jet. Need to check back in a few years to see how that went.
