Art deco mounted vase

Stunning and uncommon large size art deco french glass vase - center piece. Circa 1920. Wrought iron fixture is signed E. Dubois. Wonderful blue blown glass. (No visible signature but probably by Lorrain who was the specialist for such vases). There are few cracks or default.... not sure on this point... inside the glass. Impossible to notice when the piece is displayed. You can hardly see them from inside the glass and with strong light behind. Impossible to catch with my camera.
( Very often these vases shown cracks inside. This is because of the process to blow glass in metal fixture. When the glass cools down, it breaks but stay strong inside the metal)
Size is 33cm (13") diameter and 14cm high (5.5")
