If opal has a specific pattern, does that mean it's manufactured?

It is really likely to be a fake with a specific or repeated pattern. Nearly all symmetrical opals are fake; check if it is a perfect circle or oval. Even a small opal is well over $100, so if it's selling for less than this, it's probably manufactured.
