Topic: Similar to Orrefors Princess Crown Bowl but not. Wave signature?

[jessieduck]

Found this beautifully heavy piece that is signed in green with a wave or a very stylized "r"
The closest I can find is an Orrefors Princess Crown Bowl but mine has uneven "fingers"
I love it. I just have no idea what it is but it feels special.
7cm tall at highest
Approx 9cm diameter

Bump Could it be an ashtray?
I'm in Australia
Has the weight of lead crystal

The swirl looks like a striation swirl within the glass, rather than a signature to me I'm afraid.

Kind wishes, Nigel
