Ales Valner Glass Vase (valnerglass.com)

I would like to find out more about a vase I recently acquired. I'm very curious to find out about what year it was made, what collection it belonged to or name of it, as well as what it's worth. Any insight/feedback is much appreciated.
Item is about 13 inches tall.

Here's what I know:
Ales Valner was born in 1962 in Brno, Czech Republic. Having designed for a number of glassworks in his early career including Glass Art Princ, he went on to establish his own glassworks in 2004.

Working alongside 4 other artists, Valner's focus is on quality rather than quantity- producing colourful, free blown pieces that are highly decorative and usually sculptural in form. The limited production capacity of his small glassworks means many pieces are unique, usually specially commissioned for exhibitions across Germany & America or for private collections.
