Which term is used for screening the presence of tiny diamonds in a sample?

• A. Indicator Minerals
• B. Geochemical Testing
• C. Microdiamond Testing
• D. Ore Grade

Answer: (C)

Microdiamond testing is the term used for screening the presence of tiny diamonds in a sample. Because these diamonds are too small to see with the naked eye, the process focuses on concentrating and identifying microscopic diamonds, often starting with separating dense particles from the rest of the material and then examining the residues under a microscope or with Raman spectroscopy to confirm diamond identity. This approach is specific to detecting diamonds at a microscopic scale. In contrast, indicator minerals point to possible diamond-bearing rocks but are not diamonds themselves, geochemical testing analyzes overall chemical signatures rather than directly spotting diamonds, and ore grade refers to the measured concentration of ore in a rock, not the detection of microdiamonds.
