Heavy cut crystal salad bowl

I purchased this bowl in an op shop (Australia) yesterday for $7. It measures approx. 22cm (8 1/2") wide and 11cm (4 1/4") high. I can't seem to find this style and pattern anywhere on the internet, particularly the large scalloped edging which is about 8mm thick . I'm thinking this looks like bohemian/Czech crystal. No markings or stamps. The photos don't do it justice - it really sparkles and has a crisp, enduring ring when tapped. Any information would be most appreciated!
