What kind of opal and from where ?

[Brevicollis]

Hello, I've got this beautiful opal gifted by an elderly woman on a fleamarket and wondered if its a good quality or bad quality, what kind of opal (there are multiple like black, blue, fire, pineapple, e.t.c) and from where it originated. Im not asking how valueble it is and dont want to know any prices for it in the replies ! The colours visible are mostly cyan, blue, light blue, green, and lime, and from some angles even some red and pink spotted dots.

Thanks !

Looks like boulder opal from Australia.

Not that rare and not the best quality piece.
