Can't help to i.d your piece but I've got a fish that changes colour also,daylight it's the colour in the photo under the new low power bulbs it goes light blue,the flash turns it lilac again so can't get a pic',Keith.

WRONG!picture you may have guessed,will try again,

The fish is neodymium and that's an interesting take on its use

"an interesting take on it's use"sorry am I having a thick day or did I miss something?Keith

Over white to give a stripey effect; normally neodymium glass is used on its own or sometimes cased over red.

Right, with you now,bit slow some days,it's my age(excuses)Keith.

Thank you so much for your replies and help.
I found this topic today (see link below if it works  ) and realised that the green glow I see is lime coloured but under a long life lightbulb.  I put it near  a fluorescent tube lighting and it goes grey/sage green colour rather than lime.

I have looked at your pictures on neodymium and thanks!  they are very pretty.  This pink piece is nothing like as pretty a colour and definitely doesn't turn blue at all, so I am assuming not neodymium? 
I will have another search and see what more I can find.  And Christine thanks for the ZBS lead.  As soon as I get a minute I'll have another look.

very different to the lovely lavender/blue transformation
