Image not in english[edit]

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

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)Reply[reply]
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.

Synthetic diamonds.[edit]

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

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)Reply[reply]


"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).

Exports treemap[edit]

2014 Diamonds Countries Export Treemap.png

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)Reply[reply]

"Incandescent lighting will not cause a diamond to fluoresce."[edit]

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