Czech (?) Orange/Purple Cased Glass Bowl

This is a most unusual triangular shaped glass bowl, possibly from Czechoslovakia rather than Venetian Murano. It is a very heavy orange, deep purple, and clear cased piece.  It is six-sided and has a pleated design which goes up to a clear scalloped rim. The bottom is cut and polished, but there is no signature. It is in excellent condition. 

$65.00 OBO.
