    Here are some suggestions:

    1.Improve the lighting by adding another lamp, or by using daylight, for instance on a windowsill.
    2.Indoors use a sparkler. You can improvise by using a torch or table lamp, with ten or so LEDs, provided it is of similar colour temperature to your main lighting.
    3.If you have a camera and are shooting on white increase the exposure compensation.
    4.Change the colour intensity and/or saturation with a simple editing programme. Some come free.

    However, most gemstone dealers list three colours for blue topaz: Sky blue, Swiss blue and London blue. Which is yours? Dennis.

    Pale blue is one of the natural colours, but most people go for the darker blues produced by irradiation.
