> But there is something about diamonds that makes them divine: carbon atoms crystallizing and bonding over millions to billions of years to form structures

It does not take millions of years to form a diamond. It takes hours. The million years are atoms sitting around doing nothing before that, and then diamonds sitting around doing nothing while some of them are eventually pushed to the surface.

You can say the same thing about any mineral. There is nothing special about carbon or the diamond structure. If anything, zircons are much more significant, being the oldest minerals we can find.

> rated on a scale of color, clarity, cut, and weight.

This is nothing special. The colour of lab-grown stones can be varied almost at will, and the rest is still an issue with synthetic stones.

> Naaaaah let's just make it in a lab it looks the same.

That’s the thing, though: it does (yes, some synthetic stones have specific defects related to how they were made and they tent to be too perfect if anything, but they still have the exact same property). It’s like complaining that the meat you are eating comes from a farm instead of being hunted.

> People are being priced out of art and beauty and it's a shame economics and corruption make real diamonds dirty.

Quite the contrary. Gemstones become more accessible to more people. The diamond industry made its bed, being completely corrupted from extraction to distribution. When stones are cheap we can have discussion about their beauty instead of their prices.
