Question

What method of searching has resulted in finding the most diamonds?

Community Answer

Wet sifting is the most successful way of finding diamonds.
Question

What are the round sifting screens called?

Community Answer

Sifting screens are called "classifiers", because they are used to "classify" the soil in different grades of fineness. They're often used by people searching for gold, silver, and gems, including diamonds.
Question

How do I confirm the authenticity of a diamond?

Community Answer

You will have to take it a jeweler and get it certified. There are also some characteristics you can look for yourself: toughness-only a diamond can cut a diamond, glimmering-diamonds stand out from other rocks such as quartz, and transparency- you can see into the diamond but not through it.

Warnings

Diamond mining is hard work! Drink plenty of water while searching, especially during hot days. The search area is handicap accessible, but keep any physical limitations in mind when choosing which method of searching is best for you.
