Additional Information
A oval cut topaz that is likely irradiated to produce the blue color. There are many "unofficial" names for the blue, "sierra blue", "london blue", "electric blue", etc. They are said to refer to the shade of blue produced. They are marketing names and not defined by a true particular color.
