All common dragons have the same probabilities while trying for Emerald.

The game calculate the probabilities this way:

Rainbow has 1%;

Gemstones have 3,5%;

Sun/Moon have 3,5% (depending on the time of time of the day you get one or the other, so, technically, it's 1,75% each);

The rest (which is 92%) is divided equally between the commons. So, each common has 7,67%

All of the above is considering that you're breeding in the Cave (not the Island) whith dragons' levels smaller than 15 (which is the "normal" scenario).
