A method for nondestructively obtaining measurement information of a region within one or more ultra-hard polycrystalline constructions comprises conducing a first measurement using x-ray fluorescence by directing x-rays onto a surface of the diamond body, receiving x-ray fluorescence from the diamond body, and deriving measurement information regarding the region therefrom. A second method can be used on the same or other ultra-hard polycrystalline constructions to obtain measurement information regarding the region in a manner that is relatively more time efficient than the first method to facilitate use of the measurement method on a large number of constructions. The second measurement can be selected from the group including beta backscatter, x-ray radioscopy, eddy current, magnetic induction, and microresistance. In an example embodiment, the method is used to determine the thickness of a region within the diamond body that comprises less catalyst material than another region within the body.
