Can someone be able to tell something about this rock. The black stone one can scratch a sapphire crystal of a watch.
Your valuable comments are wisdom to be treasured. Thanks everyone.

I used the sapphire crystal of an old Swiss broken watch for the experiment.

Are you 100% sure your watch glass is made of synthetic corundum ?

I suspect you are hoping, grasa, that you have discovered diamonds.
Bring your unknowns to someone who has a thermal diamond tester. Most jewelry stores have them.
Ask them to test your curiosities.

It should only take a couple of minutes. It will identify a diamond, even a black one.
If your specimens are not diamonds, the gadget will not identify what it may be.
But you will know, they are not diamonds.

Yes thank you. I actually ordered 1 already and I am waiting for it to arrive. I am just so curious that I can't wait.

On the back case of the watch it says sapphire crystal. I tried scratching it with a file then and sand paper, there was no effect. It was slippery. Ty

Given that the black one is not a diamond, then what it is, given the hardness?

Maybe you should consider bringing your unknowns to a meeting of your closest Gem & Mineral Club and ask for help.
