Z is for Zodiac

Reached the end of the alphabet this week. I have actually blipped this before  (August 14th 2014, I think, but the link won't work!)  then it was against a ghostly green background - not the black cooker hob. It is very challenging to photograph due to the design being placed throughout the depth, width and height of the glass so difficult to focus.
I have a much simpler paperweight too - see extra pic - which has the design just embedded in the base.
