Tulip globe lampshade in white opaline glass

Pretty white glass lampshade decorated with a flower pattern in pastel shades, pink, caramel and yellow with an elegant shape and pretty details: the beaded bottom edge, the iridescent reflections at the top and bottom. It must date from the 60s or 70s. It is in good general condition, no cracks, but small chips on the upper circle, which will not prevent the installation of the suspension system and will no longer be seen since the suspension system will "encompass" this part, and an area of 1cm by 2cm with small stains that I have not managed to remove, this could be an original defect because it seems encrusted in the glass of the same caramel color as the decoration. This tulip measures 23 cm in height, for a maximum diameter of 21 cm, the opening used for the suspension is 4.5 cm.
