Abstract: | We prove that x is in the norm closure of invertibles whenever x is self-adjoint in some unitary isotope of a JB*-algebra. In the sequel, we investigate certain links between the elements of the unit ball which are self-adjoint in some
unitary isotope of a JB*-algebra and the elements which are average of two unitaries.
