Heavy stylized "Eye" sculpture...Looking for any identifying information and value!

I purchased this sculpture at an antiques shop a few months back. I have been researching it ever since I bought it, because I find it fascinatingly beautiful and I would like to know more about it...Murano? Maker? Age? Value? It appears to be a Stylized EYE, perched atop a free-form clear base. It is approx. 15" tall...3" wide...and extremely heavy! I do believe that it is Murano, just because of the glass weight (Murano glass, in my experience, is hefty!) ,the bright colors and the technique used. I also believe it was made by a glass artist from the Seguso family. However, I can't be sure. I see no markings anywhere and it has no label. If you know what this is, or have any clues I can follow, I would greatly appreciate any input. Thanks for looking!
