Good morning, @Kevinwong. I actually saw your original post about diamonds being nothing in the small hours of my morning, but thought to comment when a little more awake :)
Synthetic diamonds, sounds like a good band name, or euphemism for fake emotion, basically, a great writing prompt!
By association, I also think of the cynic philosopher, Diogenes, and his epiphany to 'Change the value of the currency...'
(or to challenge established customs and values).
I dunno that I care much for diamonds either, but heard girls do, so wed mine with one. Otherwise, crypto all the way :)
