Normally I state what I have photographed for my image but this week I shall be mysterious. :-)

 

Note added September 2020 -- the secret revealed 3 years later! :-) This is the bottom of a cracked crystal highball glass. The glass is untinted but inside I placed some colourful objects. I think I backlit it.
