actually they don't. Its just a merger of minds, they have the personalities of both gems merger into one, plus gem fusions are not permanent and can be separated with the right stimuli (gem destablizers for one).

It explains this all on the steven universe wiki under gem fusions....

Life created by this cannot be defused under normal circumstances, as the they individuals that make up the new life are sacrificed and used up, thus preventing them from being separated. fusionisms and amalgamations can be separated via the various fission powers.
