Murano style, art glass with lilac, violet and mauve marble like glass tone serving oval scallop sold or balloon dish

This gorgeous multi color violet and mauve pink glass tone server dish measures 10 1/2 x 3 1/2 × 6 inches. It does have a line scratch inside bottom. Nonetheless a gorgeous piece. I cannot identify a signature and the base is rough on the cut off area. Not sure if sold it is a murano glass. Nonetheless it is gorgeous. It is a little heavy.
