Differences between Jelly Opal and Fire Opal

[mus]

Hello,
Is there anyone to explain me the differences between a Jelly Opal and a Fire Opal?
thank you

Jelly can be any color, while fire has to be some shade of orange or orangy-red (or rarely yellow). I''m sure there are other differences, but this is one I know of. Also, jelly ones generally have pastel shades of color, while fire opal should be vibrantly colored.
