A polycrystalline diamond compact useful for wear, cutting, drilling, drawing and like applications is provided with a first diamond region remote from the working surface which has a metallic catalyzing material and a second diamond region adjacent to or including the working surface containing a non-metallic catalyst and the method of making such a compact is provided. This compact is particularly useful in high temperature operations, such as hard rock drilling because of the improved thermal stability at the working surface.
