    Hi, Paul.
    Thank you for your blog.

    I have a question about male diamond rings.
    Unlike diamond rings for women, most diamond rings for men are the kind where diamonds are buried deeply in the band and you can only see the top surface of the diamonds.
    Does diamond cut quality still matter in that kind of diamond ring?
    I mean, even if lots of light is leaked out of the bottom sides of the diamond,
    it will bounce right back when it hits the ring, won’t it?
    Because the bottom sides of the diamond is buried in the ring,
    the light that goes out of the bottom sides of the diamond gets to hit the inside of the shiny ring right away.
    It will bounce back, comes out of the top surface of the diamond and into our eyes, right?

    Please kindly explain.
    Thank you :)

    Kim, light performance doesn’t work like that. if the diamond isn’t cut well (i.e. facets aren’t positioned correctly to reflect light), the light that leaks out of the diamond doesn’t return to the viewer’s eye. Bouncing off the bottom of the ring doesn’t matter and doesn’t mean it bounces back into the viewer’s eye. Having light reflect within the diamond also causes a phenomenon known as dispersion. This light that is refracted via the facets will be seen as colored light (fire) which you do not get if the diamond isn’t well cut.

    Cut quality matters. Otherwise, you might as well place a mirror into the ring.
