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.
