Industrial diamonds are pretty useful for cutting.

- If it is an external link, it must be to a specific story, not to the root of the site.
- You may post comics from others or your own.
- If you are posting a comic of your own, a maximum of one per week is allowed (I know, your comics are great, but this rule helps avoid spam).
- The comic can be in any language, but if it's not in English, OP must include an English translation in the post's 'body' field (note: you don't need to select a specific language when posting a comic).

I think they also have applications in the scientific field, although I'm not sure exactly how.
Diamond anvils
Scribes, cutting and polishing
Coatings for high durability and wear resistance
Windows and containers for laser experiments
Semiconductor research
Physics experiments
Ringwoodite inclusions in a diamond recently (last decade or so) revealed that water exists in equilibrium with the deep mantle, far deeper than previously thought possible. This has completely changed our understanding of the chemistry of the deep interior of the earth.
This is deeper than it may seem.
Maybe an unpopular take:
Although we have basic needs, of course, like food, housing, and some entertainment, there is no true need for luxury or riches that go beyond our needs and some reasonable wants. The only reason we accumulate stuff is because there's the notion that success can be measured by our net worth. Yet, this pursuit of material wealth leaves people feeling empty and unfulfilled. It's a never-ending race for more, with no finish line in sight.
Riches are for those who do not see more meaning in life than being able to measure themselves against someone else's numbers or having the feeling of "power", which turns many into unlikeable, bitter jerks.
This proverbial diamond is nice. But it isn't more than that. /rant
Not shitting ya here. Your comment actually made me think about what useless luxuries I am chasing and what are gimmics or targets that might actually make me more happy in the long run.
Some people don't even have access to basic needs. This planet is worse than a prison due to that. at least in prison everyone gets basic needs.

I think that tale is much older than modern society.
Everything that's rare is valuable.
Even experiences are valued that way.
The dumbest person in stereotypical movies is always the one easily distracted by pretty, shiny things.
Diamonds are cool. Not as engagement rings, but as ultra-dense carbon.
They're arguably the hardest known substance in the universe. The only things that might be harder are so rare that their hardness can only be tested in simulations. That makes diamond unequaled for cutting. They also have amazing thermal conductivity. All that from a transparent rock is awesome.
Carbon in general is dope. Nanotubes? Graphene? And it's not even hard to come by? Gtfo.
Yeah but Genghis Khan was also made of carbon and he wasn't cool.
Don't forget the perfect octahedral cleavage and unique lustre!
To each their own, I don't really care how they look (other than being transparent), I just think it's cool that something that looks like glass is stronger than steel.
