They are so fucking cool. If I had the money, I’d have a room that’s just these gems+blacklights. There are some that change color based on the wavelength of UV light they’re exposed to. Some glow a different color under UV than they do under normal light. Some are both fluorescent and phosphorescent, meaning they light up in response to UV, but then they can maintain their glow temporarily. Some change color based on the angle you view them at. They’re so fucking cool.
Stainless Steel is the alloy of miracles. Fuck the naturally occurring rock, I want the alloy millions would fight to the death over for most of human history.
Holy shit I need blacklight jewelry! I got lab alexandrite and lab moissanite for my wedding ring, but I didn’t know I could get SCIENCE gems! And I do a ton of confocal microscopy where we use dichroic for splitting the wavelengths! Thank you for this link, I’m def buying all my jewelry from here from now on!
The mechanics of extracting diamonds is baffling. Hell, even gold. Cutoff grades (where it is no longer feasible to mine economically) for gold is about 2.5 grams per tonne of overburden… that’s a fucking metric shitpile of waste rock, some of which is ML/ARD (Metal leaching or acid generating).
I find the whole thing fascinating, and mining can be done responsibly, but it is not an easy thing in general
