Comment on Diamond market

  Really? I always thought it looked gaudy. Maybe that’s because people just get comically large ones that would cost more than a house if they were diamond.

    I honestly couldn’t care less about the rocks.

    But pretty colors are pretty colors.

  Moissanite is a completely different substance than diamond, it’s a silicon carbide crystal, and it’s also made synthetically so no worries about exploitation mining, it’s also cheaper

    I’m asking about the light. The lightshow produced by a crystal is down to both the optical properties of the material, but also the geometry of how it was cut.

    The image is really cool, but it only demonstrates a difference if the Moissanite was cut into the exact same shape as the diamonds.

    A prism doesn’t split light becayse of the material its made of, but because of its shape.

      Moissanite has a marginally higher index of refraction than diamond so the “ideal” cutting geometry would be different. This looks like a misleading demonstration intended to market something. They appear nearly identical in normal conditions

        That’s what I was immediately thinking.

        Getting pretty colors out of a clear crystal is more about how it was cut, than what it’s made of.

        Unless it’s something like opal that produces lightshows through completely different optical effects.

      Isn’t it both shape and material? The refractive index of the material is important in determining how much the light bends at the interface.

        Yes, but a clear crystal is a clear crystal.

        If you want to split light you can do what regardless of refractive index (as long as it isn’t zero), you’d just need to cut different angles and/or project the light onto a surface that’s closer/farther to get the same effect using a different material.

      Ah, i misunderstood, yeah, there’s got to be some rigging in that demo pic now that you mention it, however if Moissanite is essentially a drop-in replacement for diamonds in jewelry that is cheaper and looks even slightly nicer, which seems to be the case, then all should be well, doubly so if it kills the profits of De Beers. I’d ask to see the contrast IN PERSON if i was shopping for rings today though, nothing beats that.

    no worries about exploitation

    Until De Beers starts synthesizing it.

      Yeah what conditions are these scientists working under?
