how do you know if the rock you found is a diamond?

Question

I am a rock hunter and would like to know what a diamond in the rough looks like? anyone have the answer?

Answer 1

Here's an interesting way that miners use to tell.

Find a flat baking sheet and a tub of Crisco or lard. Spread a thin layer of it on the back of the baking sheet. Not much, just enough to make the pan white. Put the pain in the sink tilted at an angle not to exceed 40 degrees.

Turn the water fawcet on low so that the water runs gently over the lard.

Now put the stone at the top of the baking sheet, and let it go. If it sticks to the lard without budging, you may have a diamond on your hands. If not, it simply slides off.

Answer 2

See if the rough gem will scratch glass. That's the first clue. The rough gem will simply look like a clear stone -- something like a quartz crystal, but different in color.

It isn't coal, though that's where diamonds start. They are pure carbon which Mother Nature has "cooked" for several million years under high pressure and temperature.

Answer 3

First look at the facets if it is diamond there is nothing that can scratch it except another diamond. It is also hard enough that it will not scratch with sandpaper. It will scratch any hard rock like flint etc.

Answer 4

First, assume that it isn't a diamond. Second, check the hardness, if it scratches everything else, it might be a diamond. Third, see first.

Answer 5

Take the sample and try to scratch it with everything you've got.

If it scratches, it's not a diamond.

Answer 6

I think it would be coal that you are looking for.
