Vintage blown glass vase

I have a unique blown glass vase, signed and dated. Beautiful design that sometimes looks like flowers and other times looks like the sea. The bottom has Snoldelev 79 etched, I have found a few things written about Snoldelev but can not find anything much pertaining to blown glass or artist from that area. I did find a mug with the same colors listed for 600 dollars. Not sure why or where to look next. Any help would be appreciated.

Excellent
