Sommerso top Pedestal Bowl, Small Art Glass Dish

Small art glass pedestal bowl/candy dish.
Oval sommerso design of amethyst (purple) colour cased with clear glass.
No label or signature, and although believed to be Murano and looks like it may be from Seguso Vetri d'Arte, we cannot attribute this piece definitively to a certain designer.
In good condition with no chips or cracks - does show top surface scratches and minor nips to underside of base, and a small 'defect' on underside of base (see photo) that seems to be inside the glass itself.
12,9cm (5.08") x 9,8cm (3.86") mouth opening including glass thickness x 13cm (5.12") high
