Amazing Hand Made Cobalt Blue Signed Art Glass Vase Iridescent Drapes Beautiful!

This is an absolutely amazing cobalt blue art glass vase. It has so much going on. It really has a flow to it with drapes and pinches. It is somewhat iridescent. It measures 6 3/4" high and 7" wide. It is very heavy thick glass weighing a full 5 pounds. It is signed what looks to be N Gun, A Gun or Agua. 9/3. Really hard to make out but maybe somebody knows who the artist is. I am sure they are well known with this type of artistry.
