Rectangular cut Saint Louis crystal vase

Crystal vase cut at the wheel (considerable work) probably from the saint-louis crystal factory, not stamped 1920s/30s (it is so elaborate that there is no place for a claw), the marking of the pieces was a label at that time and not engraved. Atypical shape modern spirit, thickness 0.7cm, bottom, 1.5cm, unusual serrated border. Very good condition no scratches, only on the bottom, very clean no traces of limestone, a single accident very discreet in a small shock angle that blunted two teeth not very visible (see photos of details). Height 20cm, width 8.5cm, depth 5cm. Weight 1.5kg. Beautiful room very decorative even without flowers.
