I like this. They are already "fingerprinting" diamonds, <link> so this shouldn't be a far stretch. [+] |

Tacky. Rock wrecker? Sorry, just my opinion. Good luck! |

Doesn't even have to be a diamond. Would work great with costume jewelry. |

[dog's b.] I was thinking more on the lines of Compact disc technology . If you don't like the image just grind off the etched surface (reducing the diamond slightly). |

There would be a facetted cone like surface to etch .
The pits of varying depths and positions are on the underside faces of the diamond . The calculated internal reflection pattern off the pits and non pits builds the hologram . |

Maybe a larger than normal top viewing face might be needed . |
