Periwinkle Art Glass Vase, Handblown, Unsigned, 10.5" Tall

This is a gorgeous piece of hand-blown art glass. 10½" tall x 7⅜" wide at top, 4" wide base. I live in the Monterey Bay area where we have many talented artists around. I happened to find this beauty in a thrift store along with a few Rick Stirini signed pieces. It's possible that it may be his art. It is unsigned so I am unsure who the artist is. It weighs nearly 4 pounds. The condition of this vase is EXCELLENT! The translucent periwinkle blue is a striking color. Please see all the photos carefully and feel free to message me with any questions or reasonable offers. Thank you.
