Crystal Bowl Help Pease

Hi all, was hoping someone may know the patern of this large crystal bowl..Stands 14cms high & is 22 X 22 across the top. Very solid & heavy. Quite a deep cut pattern. The large round flower pattern has an etched design in the centre. Saw tooth pattern arount the top.

Has 3 solid feet & a 1.5cms thick base just above the fee. I have this large one & a smaller identical piece.
