My wife wears a .45 carat moissanite on her engagement ring. The stone cost 80 euros three years ago.

We'd much rather spend money on fabulous vacations or boring mortgages.

Come crashing down

Crashing down

I wish.

Nothing says "I love you" like a detonation nanodiamond

I bet there still over priced.

[–] [email protected] 9 points 2 months ago

No, I bet they are.

Good. Hope the whole industry goes bust.

I'd like to see new uses for diamonds that take advantage of their material properties. For example, the thermal conductivity of diamonds is very high.

[–] [email protected] 4 points 2 months ago

Diamond thermal paste is out there. It's okay, but like most thermal paste (besides liquid metal, which has its own issues), it doesn't give extraordinary results over anything else. People tend to really overthink thermal paste; it's going to give you maybe 4 extra degrees C, and that's already pushing it.

Graphene is an even better thermal conductor, and heat pipes are tons better than either. There's some work out there on enhancing heat pipes with graphene.

Industrial diamonds have always been on the cheap and that industry is far removed from the jewelry/gem industry, in fact a large majority of diamonds that are mined aren't gem grade, they're industrial grade. It's been growing and advancing despite the jewelry/gem market starting to fall.

and their hardness makes them useful in all saw-blades or drill-bits

Bottom falls out on commodity made artifically rare through imperailism and corruption. Is this the part where I'm supposed to feel bad for De Beers?

The free market manages to solve a problem.

I wonder how much money it's going to cost the diamond lobby to un-solve it.

[–] [email protected] 11 points 2 months ago (2 children)

To be fair, diamonds are indeed rare on earth. But what made diamond price come crashing is because we now managed to synthesise the diamonds. These "fake" diamonds flooded the market. This is good news so that we don't have to rely on exploitative extraction of the mineral.

[–] [email protected] 4 points 2 months ago

They're not especially rare, not even gem-quality ones. For several generations, almost every married woman in a western country had a diamond on her finger of some size. They found plenty of them to serve that market. The mines created artificial scarcity by colluding together.

If lab grown had never happened, diamond mines might not have been able to serve industrial customers. Industrial customers don't care how it looks as long as it cuts, and so lab grown has been good enough for decades. Thus, you can get a two-pack 4.5 inch diamond angle grinder wheel at Home Depot for around twenty bucks.

Also because newer generations just aren't sold on diamonds being a luxury item anymore. Your average Joe just isn't paying their rent or more on a diamond engagement/wedding ring like they used to because, well, that's their rent payment or mortgage for something that's gonna lose value the second they walk out of the store.

I'd buy more diamonds, but I spent all my money on avocado toast.
