A fabricated sample of a bearing ring including sub-surface non-metallic inclusions, including a first bore and a second bore extending but not penetrating a bearing raceway surface, a non-metallic material inserted into the second bore and a first and a second plug for the first and the second hole, respectively. A method of fabricating a bearing detection sample including a sub-surface non-metallic inclusion and using the fabricated sample to detect sub-surface non-metallic inclusions in production parts, including fabricating the detections sample, tuning a suitable detection probe using the sample, and using the tuned and optimized probe to detect sub-surface non-metallic inclusions in production bearing components.
