    The 150 is most likely to be the size of the diamond. 14k will mean the gold is 14 carat gold. Not sure of the ultra gem or the SD they are most likely the manufacturers mark.

    [SD] 150 14k
    Ultra Gem

    the [SD] means demensions, so the 150 must be the size and 14k is the material. The Ultra Gem shows the diamond.
