The concept of $R$ -diagonal element was introduced in [5], and was subsequently found to have applications to several problems in free probability. In this paper we describe a new approach to $R$ -diagonality, which relies on freeness with amalgamation. The class of $R$ -diagonal elements is enlarged to contain examples living in non-tracial $*$ -probability spaces, such as the generalized circular elements of [7].
