I can understand someone preferring a stone formed by natural processes over æons and discovered by a miner over one created in a factory. I can also understand someone preferring a stone crafted to exacting technical standards over one randomly found in nature. They're just different ways of looking at the world, and that's okay. Me? I kind of like the romance of a stone which formed before the first man climbed down from the trees, but I don't begrudge anyone his scientific marvel either.

  > So, why diamonds? Diamonds are generally a 'good' engagement ring feature from the chemistry/physics stand-point: Pearls will melt in a variety of acids like vinegar, along with many other 'organic' materials. Some stones also have strange chemical interactions and can change color or will patina with age (Fluoric acid, water from hot-springs, etc). Some stones are 'soft' and will scratch over time as they wear and may need to be replaced (Rhodo, peridot, etc) Some stones can build up internal stresses as they age and will become brittle (highly unlikely though, though possible) The index of refraction of many stones does not produce as large of a 'sparkle' that diamond does (though others like zircons will be much more 'sparklely') Generally, diamonds are relatively inert chemically and very very hard to scratch or damage, all while having a good enough 'sparkle' and are able to be found in large quantities. Though their prices are currently absurd, they are a good choice from a materials standpoint.

    Diamonds burn.

      At 900° C, or about 20% of the temperature of the surface of the sun. I actually thought it would be higher!

        Low enough to be burned in a house fire.

        They will also theoretically degrade back to graphite over time, the way ice degrades to water at room temperature. https://commons.m.wikimedia.org/wiki/File:Carbon_basic_phase_diagram.png https://commons.m.wikimedia.org/wiki/File:Carbon_basic_phase...

If that was the only point of distinction, I'd be right there with you. But the fact that natural diamonds are quite likely to have been mined using what amounts to brutal slave labor (even the ones that are "certified ethical," because these people have no qualms about subverting the certification process) is a pretty big issue for me.
