Embodiments of the present invention relate to superabrasive materials, superabrasive compacts employing such superabrasive materials, and methods of fabricating such superabrasive materials and compacts. One or more embodiments of a superabrasive material include a plurality of first superabrasive regions characteristic of being formed at least partially from a plurality of agglomerates, with each first superabrasive region including a plurality of first superabrasive grains that exhibit a first average grain size, and a matrix through which the plurality of first superabrasive regions is dispersed. The matrix includes a plurality second intercrystalline-bonded superabrasive grains that exhibit a second average grain size. The superabrasive material exhibits one or more of the following characteristics: (1) the first average grain size being less than that of the second average grain size; (2) the plurality of first superabrasive regions exhibiting a selectivity to be preferentially removed from the matrix; or (3) a thermal stability of the plurality of first superabrasive regions being greater than that of the matrix.
