In the introduction, please add brackets around the word "crystal structure" because it's a very relevant link to this topic. 208.95.51.53 (talk) 20:23, 12 July 2019 (UTC)

burn ?

I've tried to find info on this in the article. Can't find it. Carbon is burnable, so what about diamonds ? (I assume they don't melt and boil) Boeing720 (talk) 10:10, 31 July 2019 (UTC)

@Boeing720: Have a look at the section on chemical stability. RockMagnetist (DCO visiting scholar) (talk) 18:40, 31 July 2019 (UTC)

Thanks. But I was thinking what happens with diamonds in case of fire. Would a diamond burn if put into the flame of a regular lighter, or only if the flame is extremely hot ? Boeing720 (talk) 20:50, 31 July 2019 (UTC)

Good question! I have added some material to the section. RockMagnetist (DCO visiting scholar) (talk) 17:07, 1 August 2019 (UTC)

could the diamond page be added to the mineral category? Lopendwiki (talk) 14:17, 26 September 2020 (UTC)

 Not done. Pages in Category:Minerals should be put in subcategories if possible. This one is part of Category:Diamond, a subcategory. ◢  Ganbaruby!  (Say hi!) 15:02, 26 September 2020 (UTC)

Diamond Chemical stability.
There are some inconsistencies, and half truths across the wikipages.

1. The German Wiki page notes that Diamonds will start oxidize at 720°C (faster in a pure oxygen environment and slower in normal air). Not 690°C as this one says. Though, I'm not sure which is the correct number.
2. I also that there are more scenarios in which diamonds react. E.g. It surely reacts with Chlorine trifluoride. But I'm sure there are lots of less aggressive chemicals that also will force a diamond into reaction.
3. German page also states that diamonds dissolve in carbon dissolving (molten) metals, as: iron, nickel, cobalt, chromium, titan, platinum, palladium, and any alloy with those in them.

The German page forgets to mention the conditions under which the oxidation is self-sufficient, this page fails to mention the slower oxidation/reaction rate in air which ultimately is responsible that it isn't self-sufficient, due to not enough energy released to keep it running.
I think that is all for now, and sorry I could not provide unambiguously correct data, and links to citations.

Near the bottom of the article, under "Etymology," we have:

"The name diamond is derived from the ancient Greek Ancient Greek: ἀδάμας (adámas), 'proper, unalterable, unbreakable, untamed'"

The first instance of "ancient Greek" (the one that is not a hyperlink) should be removed to avoid repetition. 93.41.2.30 (talk) 07:39, 12 November 2021 (UTC)

Image not in english

The image showcasing major diamond mining countries is in French and not in English, despite of being on the English version of the page. 117.194.52.236 (talk) 11:54, 25 January 2022 (UTC)

Thanks for your concern. I'm not aware of any policy that says that images in this Wikipedia have to be in English. Of course, it is preferable, so I did a quick search for an alternative and didn't find one. If you're able to find or make one yourself, you're welcome to substitute it. But for now, I think the text is easy for an English speaker to understand, and of course it's reinforced by the map itself. RockMagnetist(talk) 16:48, 25 January 2022 (UTC)

Agreed. One of the biggest challenges for Wikipedia is finding suitable images on acceptable licensing terms to illustrate concepts in articles. For this reason, the rules governing images are more relaxed than those for contributed text (except for copyright, which is strictly enforced.) It's a necessity one hopes is temporary. --Kent G. Budge (talk) 17:25, 25 January 2022 (UTC)

Exports treemap

The caption below the graph of exporting countries says: "Diamond exports by country (2014) from Harvard Atlas of Economic Complexity"

However when I click on this link I see totally different data, for instance 14.71% for the US instead of 5% on our image. I played with the settings (e.g., "Diamonds, industrial, unworked", "SITC rev.2 (1962-2020)", "Net" instead of "Gross", other years, etc.) but I couldn't generate an identical tree map.

Should we remove this image?

We could also replace it by the 2020 data but I'm not even sure the data makes sense for readers as the tree map seems to merge worked diamonds and unworked diamonds. a455bcd9 (Antoine) (talk) 13:11, 16 December 2022 (UTC)

Synthetic diamonds.

Who is the world leader? How advanced is the technology of production?Neo Zweite (talk) 17:02, 5 December 2022 (UTC)

Day .

Do you mean technology for diamonds Sintes ? Where is the largest diamond sintezator? In my opinion - somewhere in Russia. Somewhere near Moskva. Plus . In Space . On space station "Soyuz".Patrug Dritte (talk) 16:12, 19 January 2023 (UTC)

apropo:

"Those potentially synthetic diamonds require more investigation in a specialized lab. Examples of commercial screening devices are D-Screen (WTOCD / HRD Antwerp), Alpha Diamond Analyzer (Bruker / HRD Antwerp), and D-Secure (DRC Techno).

"Incandescent lighting will not cause a diamond to fluoresce."

Shouldn't it say "visible light," since there are incandescent ultraviolet lights? And shouldn't "Ultraviolet" in the preceding sentence be lowercase? 67.180.143.89 (talk) 15:55, 18 March 2023 (UTC)

Terminology

The term ‘Paragon’ is used an an adjective but appears to be a noun Andyeff (talk) 08:14, 6 May 2023 (UTC)

Rarity of diamonds

This piece states that diamonds are very rare, but this is not true. Multiple sources exist to counter that notion, e.g., from the International Gem Society. Diamond production has been heavily controlled to suit specific merchants. 2001:861:5E49:DF60:DD77:2926:A831:39E3 (talk) 15:11, 1 June 2023 (UTC)
