diamond dust

The prince pounded the diamond to powder, and wrote the lady a letter strewed with the diamond dust as drying sand.

To make a very deep scratch, a wheel armed with diamond dust, which will be described later on, may be used.

For this purpose it is before all things necessary that real diamond dust should be obtained.

The wheel being set up correctly, the next step is to arm it with diamond dust.

If it does not, a little diamond dust rubbed into the side of the wheel, as well as the edge, will do all that is required.
