•  Info Cathodoluminescence image of a diamond. SEM TESCAN MIRA3. Field of view = 3,45 mm / Сreated by Pavel.Somov - uploaded by Pavel.Somov - nominated by JukoFF -- JukoFF (talk) 20:55, 16 January 2021 (UTC)

•  Comment Beautiful. What is the texture we're seeing below the diamond? The background object, I guess, but because it's notably wavy and therefore calls attention to itself, I think it should be identified. (Also, very minor point, but wouldn't the relevant category be diamonds, rather than gemstones?) -- Ikan Kekek (talk) 21:45, 16 January 2021 (UTC)
  • Ikan Kekek unfortunately Pavel.Somov will not answer you, the participant appears in Wikimedia projects only at the time of the contest Science Photo Competition. JukoFF (talk) 11:53, 17 January 2021 (UTC)

•  Comment Maybe we should reconsider these nominations at that time, when the information I'm asking for could be added? -- Ikan Kekek (talk) 13:08, 17 January 2021 (UTC)

• Why? We judge the quality of an illustration, not the description of that illustration, don't we? JukoFF (talk) 18:31, 17 January 2021 (UTC)

• Educational value is a factor, right? We've certainly treated it as such. -- Ikan Kekek (talk) 22:25, 17 January 2021 (UTC)

The texture below the diamond is almost definitely carbon tape. It is common practice to put specimens on carbon tape for scanning electron microscopy. The carbon tape allows charges to drain to ground while the specimen is under the electron beam. 2406:3003:2077:ABF:C454:5060:EB03:8BEF 14:24, 24 February 2023 (UTC)

•  Support Now here is a remarkable image photographed with interesting light. -- Colin (talk) 18:44, 17 January 2021 (UTC)
•  Oppose lighting, can't see sides of the diamond.Seven Pandas (talk) 22:44, 17 January 2021 (UTC)
  • Seven Pandas, it wouldn't be the first time I demonstrate my ignorance on these pages, but my understanding is that we are seeing the diamond bombarded by electrons in a scanning electron microscope and itself glowing these colours (cathodoluminescence). Therefore, the lighting here is literally the subject and if you don't like how diamonds cathodoluminescence, you'll have to have a word with God about it :-). -- Colin (talk) 14:24, 19 January 2021 (UTC)
•  Support I love this and consider it an FP, but I sure as hell hope my questions are answered when this user returns, because it's a problem to have scientific images that aren't sufficiently explained. -- Ikan Kekek (talk) 03:46, 18 January 2021 (UTC)

•  Support with Ikan's reservations. I wish it were sharper, but I take into account Colin's explanation above. Daniel Case (talk) 20:24, 20 January 2021 (UTC)
