Wide rim bowl

My father traded some work for this bowl with an antique store in the mid 60's.

For some reason, my mother always thought it was Steuben.

It measures 12 inches across the brim.

Some light comes through it when held up towards a light or sun.

Purple / lavendar in color.

Can't find any markings on the bottom or anywhere else.

Have looked through several thousand google images with no luck.

Have any ideas what it is?

Thank you,

Tony
