hello and welcome to the board
I don't know anything about cut glass so can't help you but hopefully someone will be along who may be able to. Sometimes these things take a few days as not everyone is on the board all the time, so please keep an eye out in case someone else posts.
I had a quick search but couldn't see anything, however given your location is Hong Kong it might also be worth searching Japanese glass as they have done some wonderful cut glass. I don't know anything more to help you except it might be worth keeping your options open for Japanese as well
