Which is also actually rare, isn’t it? And it’s wonderful to work with for jewelry, isn’t it?
Diamonds are probably a better analogy.
You should probably look up the history of De Beers and the most successful advertising campaign in history.
(Fun fact- in the forty years of the concentrated advertising from 1939 on, which consisted of the slogan "A Diamond is Forever," seeding European royalty and Hollywood stars with diamonds, using social pressure to close down the secondary market, and promoting the idea of "diamond engagement rings" ... which weren't a thing before that ... De Beers basically created the modern diamond market and moved it from the "millions" to the "billions" of dollars in a few decades.)
