Microdiamond testing screens for the presence of which material in a sample?

Microdiamond testing screens for the presence of which material in a sample?

• A. Overall hardness
• B. Macroscopic crystals only
• C. Magnetic properties
• D. Presence of tiny diamonds

Answer: (D)

Microdiamond testing is used to detect the presence of tiny diamonds in a sample. These tests target microscopic diamond particles that may be dispersed in a material, which matters because diamonds are often embedded or dispersed in industrial materials or in synthetic processes and might not be visible. It isn’t about measuring hardness, which is done with other tests, and it doesn’t rely on magnetic properties, since diamonds themselves are not magnetic. It also goes beyond macroscopic crystals because it seeks confirmation of tiny diamonds regardless of whether any large, obvious crystals are present. Therefore, the test specifically screens for tiny diamonds, making that option the correct one.
