If a stone is dichroic (transmits two colours at once) you will see the two distinct colours when viewed through a dichroscope.

You can see the two colours by viewing the stone from different directions, but this often impossible if the stone is set in jewellery, it's easier to use a dichroscope.

{Is it easy to use?}

For coloured stones only.

{Further information}

This is a standard gem tester used by gemmologists, it does not come with instructions, you are expected to know how to use it (a bit like a bicycle, it does not come with instructions telling you how to ride it).

If you are new to gemmology I strongly recommend the book Gem Identification Made Easy. This book systematically works its way through all the optical testers, telling you the theory behind them, what they will test, and how to use them. To get your discount (£25.00 instead of £29.50) tick "Add the Gem ID book" when you order the dichroscope.
