The diamond was a cold stare in a frigid wind.
They'd smuggled the diamonds in a tub of bovine eye balls, all that was left on the floor was dead eyes staring into nothing, a few of them squished and leaking their jelly.
The diamond sat there like a chip of ever-cold ice, stubbornly resistance to all attempts to warm it.
The diamond, that spectacle of social status and entitlement, sat upon her finger, welded to a strangling band of gold.
Money is emotional indifference, and diamonds are money - so what can they do to love but slowing destroy it?
They took a common clear rock, polished it to a shine, restricted supply, made it a part of finding a lifelong lover and raised prices. There's nothing like falling for crude commercial manipulations to say, "I love you."
