Rough diamonds usually resemble lumps of pale colored glass. They often have an oily appearance and don’t sparkle. Very few rough diamonds are actually gem quality. Only those with the very palest colors, or are colorless will pass the test.

How do you identify a natural rough diamond?

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.

Why are rough diamonds so cheap?

An octahedron has 8 faces shaped like an equilateral triangle, in the case of a regular octahedron. An octahedron has 12 edges. In a regular octahedron, the angles between the edges are measured at 60° but the dihedral angle is measured at 109.28°. The formula to calculate the surface area of an octahedron is 2×√3×a2.

How do you test a rough diamond at home?

Hold the corundum firmly against a table and scrape the suspected diamond against the corundum. If it creates a visible scratch, the crystal is a diamond. If it doesn’t create a scratch, then it is a different mineral. The Mohs Hardness Scale scientifically rates crystals by hardness.
