This is my idea:

Every spaceship needs to keep the pressure inside so people will be able to survive inside without major incidents. The ship landed on Earth and let the gems in and out of it, so there was a transfer of gases from within the ship and the planet's atmosphere. Then, when it  took off again to space it had to keep the gas pressure locked again. As gems don't breathe, their technology is not made to be selective with the gases to keep inside, so whatever that doesn't disturb is okay. Luckily for Steven, enough oxygen could get inside the ship before they left Earth.
