Topic: Unusual Perfume Pot or Ornament - Studio Glass. Any help with ID pls?

[Valsky]

Hello again,

Here is an usual piece.  It has a 'well', possibly for perfume (and did come with a stopper though I'm not at all sure this is original).  It has the most stunning suspended colour around the inner well and feels of high quality to me.  It is extremely heavy as it is mostly solid glass and measures 5" high and almost 3" wide.  There is no pontil, just a cleanly polished base which, in the right light, does display 'layers'.  On this have been applied little pads to avoid damage to the glass and surfaces 
I'm afraid I'm not describing this very well or doing it justice but hopefully someone out there may recognise this work and help point me in the right direction.  I know nothing at all as I bought it via eBay (UK) about 8 years ago and there was no info given.

Many thanks,
Vx
