"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]

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]

Chemistry

Wow, is this a bad article. The lead states:"Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen)." This is absolute rubbish. It isn't its "rigidity" that gives bulk diamond its impermeability (if that's what is meant by contamination). It is easy to "contaminate" a diamond CVD film with you name it. How big is the difference between contaminating a 1 inch cube (say) of pure iron vs. pure diamond? Not much. Ion implantation into (the near surface of) a diamond is also trivial. If the editors meant that NATURAL diamonds (on Earth) are typically quite pure, then SAY THAT! I suspect, but just an ignorant suspicion, that diamond must transition between impure high-carbon 'stuff' to the pure allotrope. I expect that at some point there's LOTS of contaminants in the nascent diamond. Aren't most natural diamonds black? What's that?? (the preceding is a digression, I'm ignorant on their natural occurrence.) There are so many FALSE statements in this article that it needs a total rewrite. There are many other bloopers but I don't have the patience to list them all. (For instance, did you know that hydrogen will leave an ash when burnt? No? Well, just read this article. When a diamond burns (in O2), any contaminants are left as ash. Ridiculous. (as is the assumption of complete combustion of the carbon) Another false claim is that diamond contains the most atoms per unit volume. (aside: at first, I thought the editor meant per unit cell volume!, not sure why s/he used the word "unit" since it doesn't add clarity (but it is not wrong)). Estimates of hydrogen density in the sun's core is ~10,000 kg/m^3, and without qualifying pressure and temperature the claim is likely false. I could go on...)40.142.183.146 (talk) 20:59, 20 August 2023 (UTC)[reply]
