Synthetic diamonds.

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

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).

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)[reply]

"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)[reply]

Terminology

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

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)[reply]
