We discussed diamonds a few years ago.
I considered investing in diamonds briefly around 1980. Rejected doing it. They're excellent for smuggling wealth across borders, but they fall short in many ways. Quality standards are subjective. Big spreads. Easy to buy but hard to sell. Popular in US but not in many other countries. Price used to be controlled by Debeers. Synthetic diamonds getting better all the time.
When I was in law school I read an article about investing in Scotch whisky, which was briefly a hot thing, like wine and now vodka. A few years ago every doctor was building a wine cellar. Some of the rarest collectible wines were counterfeits.
You never want to invest like a doctor!
