Dichroscope, tube

Summary

A tube 50mm long X 12mm dia.

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?

Yes.
