Which multiplayer level iterations do you get gems?

Is there a chart of which each of the multiplayer level gets you gems?

I just finished banners 11 times, and on both 10th and 11th times it gives you 4 gems each. Anyone else knows the other "gem levels"?

I think it's random. Then banner and the armour usually give me between 3 & 5 gems. Everything else except sushi & teapot give me 1 to 3 gems randomly. But it's random, you'll either get a random amount of coins or a random amount of gems.
