[@wasd____]

@@googleeatsdicks They destroy them because their value as industrial diamond dust / grit / whatever that they could sell today would be more profitable than eating the costs of security and storage for years while the diamonds sit around in a box on a shelf not being sold.

[@tsoc_ic3yic3y64]

@AlexisBubba15 and how brital it will be

[@evilsharkey8954]

DeBeers and the other diamond companies hoard the gem quality diamonds for future sale. They use low quality industrial diamonds for industrial purposes. Remember, most diamonds are not gem quality. For diamond knives, lab grown diamonds would be better since they have fewer imperfections, and they’re not controlled by diamond cartels. My school had an electron microscopy lab, and they had a diamond knife for cutting thin sections (less than a micron thick) on the microtome. It’s not as exciting as it sounds. It’s really just a really sharp diamond wedge 4mm long mounted in a block. Diamonds would be useless for a regular knife because they don’t get big enough, they’re too costly to machine, and they break very easily. A single fragment of grit in any of our specimens would have chipped and ruined the lab’s diamond knife. I used glass knives because I didn’t want to risk it.

[@MatthewSmith-sz1yq]

Dude they don’t destroy gem quality diamonds. It was back in the good old industrial revolution, diamonds were actually quite cheap and not connected to wedding rings. Then diamond mines formed something very similar to OPEC for diamonds, where they agree to set quotas and store any surplus. Also, they launched arguably one of the most successful advertising campaigns of all time, changing diamonds from being something which was just an odd, hard rock that could look pretty to being permanently linked to marriage, something that is almost as common as birth and death. The saying “a diamond is forever”? That was part of that campaign. When you really think about it, you can’t help but be impressed, these guys managed to take an odd type of rock that was somewhat uncommon, and make it worth more than gold, inextricably link it to marriage, and do all of this in less than a lifetime.

My first gift from my now husband of 22 years, was a tanzanite and diamond ring (not lab created). After we married he bought the matching necklace for our 1st anniversary. Since then, besides other jewelry (I’m a Taurus ;), he gave me a lovely alexandrite (lab created) later mounted into a pearl enhancer pendant (college graduation gift). For our 15th anniversary was a 1.25 ct. black diamond solitaire he mounted in my grandmothers old wedding band and 0.75 cts each- black diamond earrings (lab created). For our 20th anniversary a 1.25-ish ct. blue-green diamond solitaire (lab created). My favorite part is that he knows I’d prefer solitaires so that I can always change my “ring” and studs with enhancers, especially antique ones, we buy when off exploring some other city or spending the afternoon perusing our local dealers :). The fact that some are lab created makes me even more happy knowing that they weren’t apart of someone else’s suffering and they are better quality than most :).

You should have imcluded Benitonite: Benitoite occurs in a number of isolated locations globally, but gemstone quality material has only been found in California at the Benito Gem Mine where it was first discovered. It has been correctly identified in Montana, Arkansas, Japan, and Australia although they formed under slightly different conditions and only grow large enough to be considered an accessory mineral. In 1985 benitoite was named as the official state gem of California.[7][8]

[@WarrenGarabrandt]

9:18 terminology clarification: Sublimation is the transition from a solid directly to a gas. For example, dry ice sublimates directly to carbon dioxide gas without passing through an intermediate liquid phase. Deposition is the opposite process where a vapor transitions directly to a solid. The semiconductor industry uses it to make thin films. You can also see deposition when warm, humid air blows over a very cold surface, such as when you exhale onto a cold windshield in a car; the water will deposit directly as tiny ice crystals on the glass. Some people do use sublimation to refer to both directions of this process, which is rather confusing. Some people use condensation to refer to deposition, but condensation usually means going from a gas to a liquid, not directly from a gas to a solid.

@@KnakuanaRka They are actually very boring. I'd rather have garnet or emeralds for jewelry.

Diamonds are for people who fell for the Marketing Hype 😂

My husband asked me if i wanted a dimond or a house i said a house.

[@lucienpetersen9010]

Yesss!

[@sakura2974]

I bought a ring online and it wasn't sized properly because we didn't have the tools. Took it to a jeweler who could resize it and when he gave it back he told me the sapphire in the setting was lab-grown. I was thrilled.

[@glenngriffon8032]

Why couldn't fingerite be called "Larryite" that sounds a little better.

[@ganaraminukshuk0]

The most likely explanation: we usually go by last names. The immature explanation: Mineral in some place called Cummington: Someone named Finger: Hold my beer.

Corundum Cottages have the best stones!-) Snyderite, Red Rainbow Obsidian, and lightning ridge Black Opals!-)

Blue Diamonds make you cry, Pink Diamonds pretend to be simple quartz, Yellow Diamonds conquer ruthlessly, but White Diamonds... watch out for dey iz cray cray o_O

[@safir2241]

De Beers is shaking

[@logicplague]

The cost also comes from the months in some cases that it takes to cut those gems, and you don't get a do-over if you screw up, say, the largest pink diamond ever found.

[@BrandonOttosen]

me: got half a pound of star garnet on the counter (can only be found in 2 places) lol

[@Ryukai-san]

My Favorite is 'Blue John' only comes from 2 mines in the UK, both of which are mining the same single deposit (they are next to each other).

[@truskakwa]

It's seriously comforting to me to watch you speak about something so unrelateable so excitedly :)

[@Gulgathydra]

I was hoping they were going to cover alexandrite. 😢

[@24emerald]

@Gulgathydra ... I agree alexandrite is a cool gem.!

[@ItsLoriK]

I know! I can't remember how much I spent on a tiny super included one. I actually thought they were rarer than Tanzanites.

[@24emerald]

@Lori K ... yes, by size and quality it is definitely more valuable. Keep in mind it is now synthetically grown as well. And even natural ones are usually treated for color.

[@Gulgathydra]

@@ItsLoriK It's not just the rarity, it's that they change colour under artificial light! I'm sure you know that, I'm just stating it because I think that warrants its inclusion in the list.

[@desireemills6613]

My engagement ring is alexandrite :D

[@hibenjenny7816]

@ 9:18 you describe deposition but call it "sublimation". Sublimation is how your ice cubes disappear in the freezer without intervention. Thank you for making a correction and putting out such marvelous info bits.

[@riripari2042]

Talk about diamonds got me to perk up. Pretty much listening for Steven Universe and possible characteristics to compare.

[@Barnardrab]

Thanks for the shoutout on the camera course. I'm already a paid subscriber to SkillShare and I've been wondering how cameras work.

[@zeratullotus2790]

Ahaha! "...aren't *cut out* to be gemstones." I dig it ;p

[@StoneTitan]

From watching Game of stones, I can say raw Tanzanite is one of the most impressive stones i've ever seen. The treated version of it though is to me like any other jewelry, nothing to really peak my interest. a Gemstone that's square shaped and changing from blue to red to viollet is just awesome. Sadly I have little to no reason to spend that much on something that i'd never use.

I'm tryna sleep but I *need* to know wich minerals are *cooler* than *diamonds*

[@MrMagicBlox]

@9:20 you mention that sublimation is when a gas turns into a solid. I was taught that it was the other way around.

[@papinkelman7695]

I got an arcanite crystal from thorium today.

[@josorr]

9:17 When a gas transforms directly to a solid is called deposition, not sublimation. Sublimation is passing from solid to gas.

[@brandonmetcalf1141]

hey hank can you do a video on the newest elements?

[@jackielinde7568]

Eh, there's not much there, other than the "Yay! we did it". Sadly, they cannot synthesise enough of the new elements to do experiments with them, and what they do synthesize doesn't last very long. The KZbin channel "Periodic Videos of the Elements" has a few on the subject. Oh, don't forget they also have Dr. Polikov's fabulous hair, too.

[@pikmaniac2643]

at roughly 9:20, I just want to point out that sublimate would be the reverse of the process you're trying to describe, as sublimation is the direct conversion of solid to gas. Deposition is when a gas turns into a solid without liquid transition.

Question: Hexaferrite? Iron pressurised so much that it forms hexagonal bonds with more iron atoms? Is it a thing?

Man, Hank sure does get passionate over minerals.

[@Diamonddavej]

My rarest mineral in Umbozerite. It's found in 3 places - Shkatulka pegmatite, Pegmatite No. 60 and Mt Kedykverpakhk, all within 10km of each other.

[@jotaro4874]

This was probably the best ad about skillshare I've seen, i legitimately thought you were praising photographers

[@GiustinaLoguercio]

While what was said at 4:25 abour tanzanite and the industry is vo very true, there are many jewelry companies that are now selling unheated tanzanite specifically for those changes in color and hue. I work at Kay Jewelers, and a few of the name brands we sell have that deeper color of tanzanite in their line. While most of our tanzanite is lighter in shade, the ones from designers like Le Vian and Neil Lane are much darker/deeper in shade and hue.
