Methods of evaluating a superabrasive volume or a superabrasive compact are disclosed. One method may comprise exposing a superabrasive volume to radiation and detecting a response of the radiation when it interacts with the superabrasive volume. In one embodiment, a boundary may be perceived between a first region and a second region of the superabrasive volume in response to detecting the response of the radiation. In one particular embodiment, a boundary between a catalyst-containing region and a catalyst-diminished region of a polycrystalline diamond volume may be perceived. Additionally, a depth to which a catalyst-diminished region extends within a polycrystalline diamond volume of a polycrystalline diamond compact may be measured based on the monitored response of the radiation. In a further embodiment, a non-planar boundary between the two regions may be mapped. A system configured to evaluate a superabrasive volume is also disclosed.

1. A system configured to evaluate a superabrasive volume, the system comprising: a radiation source;a radiation detector;calibration data for correlating an amount of detected radiation to an indicated depth of a first region of at least two different regions of a coherent matrix of a superabrasive volume, the indicated depth being approximately 500 μm or greater from a working surface of the volume superabrasive material. 2. The system of claim 1, wherein the calibration data comprises a first measured amount of radiation associated with a first depth and at least a second measured amount radiation associated with a second depth. 3. The system of claim 1, wherein the calibration data is designed to correlate the amount of detected radiation to the indicated depth of a first region of a polycrystalline diamond volume. 4. The system of claim 3, wherein the calibration data is designed to correlate the amount of detected radiation to the indicated depth of a catalyst-diminished region of the polycrystalline diamond volume. 5. The system of claim 3, wherein the calibration data is designed to correlate the amount of detected radiation to the indicated depth of a cobalt-diminished region of the polycrystalline diamond volume. 6. The system of claim 1, wherein the calibration data is designed to correlate the amount of detected radiation to the indicated depth of a superabrasive volume exhibiting a coercivity of about 115 Oerstads (Oe) or more. 7. The system of claim 6, wherein the calibration data is designed to correlate the amount of detected radiation to the indicated depth of a superabrasive volume exhibiting a coercivity of about 115 Oe to about 175 Oe. 8.
