Well the Tesla will definitely get you a lot more utility. In fact any car is probably a better purchase than any diamond. Probably depreciates less quickly too...

  I'm not sure that's true. Teslas still depreciate at a rapid clip. Many cars will depreciate at 40% once you drive 50k miles on them. Tesla may get a break on that because of their brand, but as long as Tesla keeps punching out cars, they will depreciate. The issue with diamonds is that once they're cut and given to someone else as part of a ring, they immediately depreciate. Because, as the diamond marketing agencies point out: "Who wants a second hand engagement ring?" That said, raw diamonds (cut or uncut) hold their value. While DeBeer's has a stockpile of diamonds, they only let a fraction of their holdings out into the market every year to keep the prices artificially high. Which get turned into rings, which then depreciate immediately.

I don't think the next application of lab grown diamonds will be rings and necklaces: https://www.extremetech.com/extreme/212422-this-new-high-power-diamond-laser-can-cut-steel https://www.extremetech.com/extreme/212422-this-new-high-pow... It's weird. The most popular shape of diamond is about to become a ~10 to 50cm long rod, not even polished (not very shiny at all, it's somewhere between white and light grey and looks like it's covered in fine dust, like a natural diamond in a regular shape). It's already that way for Rubies: https://youtu.be/KzI3vaIb0aI?t=78 https://youtu.be/KzI3vaIb0aI?t=78 The positive is: those rods aren't very expensive. You want to score this Valentine's day ?

(this is likely made by buying such laser rods and cutting them up) (corundum is the name of the material, Rubies and Sapphires are the forms of it. These will be cut rubies. They're quite spectacular looking)
