The diamond belongs to the cubic cristallyne system (all three axis with the same size and with 90º angles), that's why you get those shapes, such as cubes, dodecahedrons, octahedrons, trapezohedrons and even a combination of a cube and a dodecahedron; these are the product of its internal molecular pattern that forms cubic unit cells.

Yes they’re not expensive when raw but the price gets increased dramatically when skilled, slow, difficult work is put into cutting them into nice shapes. Then they’re further increased in price at the jewellery shops to sell to consumers.

@roywapsy3367 5 лет назад

@@timsanpedro1219 no, that means that there are only about a thousand in the tray. I'd guess that there's at least 50000 pieces so about $30 dollars a piece. plus, the value of the diamond pieces depend on their size, shape, colour and cut rather then their weight.

@ProTasiable 5 лет назад

frostman1_ there’s waaaaaaay more than a couple thousand. He said the little rectangular tray at 2:25 had 1490 diamonds in them and that was tiny. So the huge tray must have atleast 100,000 in there possibly more. That makes each diamond only worth around $10 each. That’s just rough figures but the point is each diamond is not that expensive.

They do this with other products as well, such as gaming consoles. For the first year, they only release a certain amount at a time, to keep the value from depreciating. Nintendo frequently does this. Another example is high end clothing companies, instead of putting items that don't sell on clearance, they would rather destroy them totally. The worlds biggest oil companies do this as well.

Strongly florescent diamonds are less valuable because they look cloudy in sunlight (which contains UV). If you look carefully, you'll notice that on sunny days tonic water and some plastics fluoresce slightly and look cloudy, it's the same effect. The look you get under a blacklight like in this video you'd never normally see.

@AxcelleratorT 5 лет назад

As a mineral collector, it kills me to know almost all those large, well formed diamond crystals will be cut. Leave them natural! They're more pleasing than cut stones and a hell of a lot less cliche.

The explanation can be found in a thousand books. The professor's infectious love for the subject matter of his life's work can't.

I wonder if an engagement ring loses its lustre when you work with thousands of diamonds everyday?

@ronaldderooij1774 5 лет назад

There is always gold...

@RannonSi 5 лет назад

I don't think so. Considering that you're able to see just how much works get into making them (and that's excluding the ring itself) and more importantly the sentimental value, which to be honest is the one thing that should matter.

In highschool I worked at a small jewelry shop. One of my tasks one year was to measure, organize, and label all the loose sapphires, rubies, emeralds, and diamonds (and there were hundreds altogether). It took months to complete that task, and I think by the end I liked looking at the stones even more than when I started. It wasn't the same kind of awe, but it was still completely fascinating. There's a reason precious stones are still highly valued (besides bogus marketing schemes like de Beers'), they really are beautiful!

Am I the only one who saw the crystals and thought, "I wonder how cool it would be to have a set of dice made from diamonds to play D&D with?" Hell, as long as they rolled randomly, I wouldn't care how impure they were.

Could buy some clear quartz ones for pretty cheap, would still look cool.

Jack Linde I suspect it would be difficult to cut any other shape than the octahedron (d8) and it’s dual the cube (d6).

I wasn't surprised at the octahedron shaped crystals, knowing the lattice structure that carbon forms to make diamonds. However, the cubic shapes were a surprise. I wished the professor would have talked more about the chemistry (and physics) of carbon in diamonds. The heat properties is one reason people are trying to create lithographic techniques to grow computer chips.

@ragnkja 5 лет назад

Jack Linde The cubic diamonds look like very truncated octahedra.

@sundhaug92 5 лет назад

Computer chips are already made using photolithography though

@jackielinde7568 5 лет назад

@@sundhaug92 Except those techniques are for silicon and germanium chips. They don't work anywhere nearly as well on carbon (diamond). Hence why I said they're trying to develop them for diamond surfaces. If you could get a diamond computer chip, you could run it many magnitudes faster without as much need to regulate the voltage as you do with silicon. I wouldn't say water cooling CPUs would be a thing of the past, BUT, you wouldn't need it for anything BUT breaking computer processing and computational benchmarks.

@@jackielinde7568 Aha, yeah that makes sense. I'm not sure how far you could push graphite, might get the node-size down, but what about frequency-goals
