Murano high quality Style Hand-blown Glass Conch

This is an absolutely beautiful piece. With my high quality research I found this could be a Archimede Seguso but I do not find any marks. I know that there is some if his work that only had paper labels. There are also bubbles in the glass which is also characteristic of Murano glass. The vibrant blue and white tipped in a amber color. The body is encased. There is one little chip on the stretch of the shell which is photographed. The pontil sanded smooth. The shell measures approximately 10 inches long and approximately 5 inches wide.
