Sapphire Olive Egger or Sapphire Gem?

[StizzyL17]

Is this a Sapphire Gem or Sapphire Olive Egger? I was told it is one or the other. Perhaps I just have to wait a few months until it starts laying eggs.

Sapphire gems have single combs, so if it doesn’t have one, it’s probably a sapphire olive egger.
