Which term refers to screening for the presence of tiny diamonds in a sample?

• A. Dense Media Separation
• B. Ore Grade
• C. Grease Belt
• D. Microdiamond Testing

Answer: (D)

Screening for the presence of tiny diamonds in a sample is called microdiamond testing. This approach focuses on detecting diamonds that are too small to see with the naked eye, often by examining the sample under a microscope or using specialized analytical methods to confirm diamond presence. It’s a first-step diagnostic tool in diamond exploration and processing that tells you whether there are diamonds worth pursuing further. The other terms refer to processing or evaluating ore after diamonds are known to be present: dense media separation is a bulk separation method based on density, ore grade measures how much diamond content is in the ore, and a grease belt is a device used to recover heavy minerals during processing.
