Isn't it remarkable what is revealed, Anne.
Anne: The polariser really makes a difference to the view Frank.
That iridescence is beautiful!
Anne: You only see this when the polarisers are at a particular angle.

I suppose this iridescence wouldn't be seen by the naked eye?
Anne: That's right - the slide on its own looks rather boring, but once there is a polarising lens either side of it and they are turned to a particular angle, all is revealed.

You must get enthralled as each new stone shows its beauty. Thank you for sharing
Anne: You are welcome Lisl. Yes it is always a delight to see what the results are as I move the slide and polariser.
The rock of the Hebrides
Anne: I always think this type of slide is very maplike.
I like the dark masses...
