Glass Chatroom Board

Hello everyone...I haven't visited in ages. The Summer has been packed with family and friends visiting. (Love them as I do, I'm peopled out.) I need an island to sit, relax and get my Ebay store together.
Anyway...I bought these over a year ago and just getting around to listing them. I discovered a signature...Anyone recognize it. The picture doesn't do it justice ( I have a set of 6) Beautifully blown glass...very iridescent. I've been trying to find an ID for hours and would appreciate any help. I found similar glass by "Estaban Prieto"...but that's not the signature:

I'll stick around for a bit and scroll to catch up.
