Or you could use the algorithm='unimodular' option to random_matrix.
sage: random_matrix(GaussianIntegers(),2,algorithm='unimodular')
[-429*I + 54 -I - 10]
[ 43*I - 1 1]
sage: random_matrix(GaussianIntegers(),2,algorithm='unimodular')
[ 6*I - 7 -7*I - 12]
[ I - 1 -I - 2]
sage: random_matrix(GaussianIntegers(),2,algorithm='unimodular')
[ -6*I + 29 -221*I - 103]
[ I + 9 -74*I - 9]
You'd need to define your other rings and plop them in the right spot, of course.

You'd need to define your other rings and plop them in the right spot, of course.course. Edit: such as follows, though there are probably better ways to get this ring. In particular, be careful since the integral closure of $\mathbb{Z}[\sqrt{n}]$ isn't always equal to it, but depends on the residue class of n (mod 4), if I recall correctly.
K = NumberField(x^2 + 2, 's')
OK = K.ring_of_integers()
for n in range(3):
show(random_matrix(OK,2,algorithm='unimodular'))
