Hello Arrow, welcome to the forums!
 There is not much I can tell from the picture but there are some home tests that can help confirm if it is opal or help identify it if it's something else. Scratch Tests Opal hardness Mohs Scale= 5.5 to 6 Streak Tests Opal streak= white Specific Gravity Test Opal Specific gravity= 2 to 2.25 These tests can help with your other rocks also.
