How do you identify a rough diamond?

Put the diamond under the loupe or microscope and look for rounded edges that have tiny indented triangles. Cubic diamonds, on the other hand, will have parallelograms or rotated squares. A real raw diamond should also appear like it has a coat of vaseline over it. Cut diamonds will have sharp edges.

How do you know if a rough diamond is real?

The only hardness test that will identify a diamond is scratching corundum. Corundum, which includes all rubys and sapphires, is 9 on the hardiness scale. If your suspected diamond crystal can scratch corundum, then there is a good chance that you found a diamond. But NO OTHER HARDNESS TEST will identify a diamond.

How do you test a diamond with water?

This one's easy: Get a glass and fill it with water (it doesn't matter what type of water you use). Drop the diamond into the glass of water. Due to the high density of diamond, when dropped into water a real diamond will sink. If the diamond floats to the top or middle of the glass, it's fake.

Most are found in kimberlites, which are pipe-like formations created as a result of volcanic and tectonic activity.

How do you separate a diamond from a rock?

The most common separation method is called dense media separation or DMS. A DMS plant also uses the principal that diamonds are heavier than most of the surrounding rocks and minerals. Most modern DMS plants utilize a hydrocyclone (or 'cyclone'), which is essentially a large centrifuge.

How are diamonds separated from crushed stone?

Diamonds are concentrated in sluices when the water levels of the streams are high. If there is a dry season, the digging is done then to unearth the gravel, and it is separated for diamonds in the wet season. Sometimes an underwater dredge is used to scoop sand and gravel off the stream bottom or ocean floor.

Can diamonds be found on the surface?

Most surface diamonds are found on sunny days, two to three days after rainfall. Allowing time for the dirt to dry helps the diamond's metallic luster stand out against dark diamond-bearing soil. After day three, the chances of finding a diamond on the surface drop steadily.
