Summary
Scriber, 150mm long, carbide tip.
Detail
For testing 'rough' (uncut) diamonds -a good simple method, because most (not all) gemstones can be scratched with a carbide tip whereas diamond cannot.
For testing CUT diamonds: draw the tip across customer's precious gemstone, if it scratches it, it's not diamond (then the customer sues you for damaging their precious gemstone). Remarkably, customers do buy these as a 'cheap' method of testing cut diamonds, they say, "It's OK, I'll be careful!".
Is it easy to use?
Yes.
Limitations
Stones (including diamonds) are not necessarily the same hardness in all directions. Diamonds (although hard) are also brittle, it is possible that you will chip or crack the stone.
Once scratched, a polished gemstone is damaged and probably becomes worthless.

Can I use this pen to text my diamond
These are for testing minerals (found in the ground) not cut gemstones.
Sure it will “test” your diamond but you risk cracking or chipping it (diamonds are brittle), and if it isn’t diamond, you are likely to scratch a valuable gemstone and render it worthless.
