Only diamonds can damage other diamonds (or, of course, extremely heavy weights). Possibly if the katana was diamond-studded, or the edges were made of diamonds. I suppose if you could swing it hard enough you could shatter the diamond (like the heavy weight thing above) but you'd have to have superhuman strength.
Brilliant Cut, or Round Brilliant cut as it can also be called, is a round diamond ;its the generic and most common shape you will see for a diamond in jewellery, especially engagement solitaire rings.

A laser can burn through a diamond and be used to "cut" it, though it might not be pretty. As for jewelry applications, the traditional method of splitting a diamond is to "cut" it with a hardened steel knife. The knife is finely sharpened and hardened, and placed against the diamond to be cut. The knife is then struck with a small hammer. Thus the action is one of splitting, not really cutting. The cut is carefully positioned as to take advantage of the internal crystal structure of the diamond. A hammer can be used to "smash" a diamond and break it, but this is a poor use for a hammer as well as a waste of a diamond.

The objective is not to cut the diamond quickly, the objective is to cut the diamond in order to follow the plan for the cut. The plan is designed to maximize the natural assets of the stone, such as its colour and/or clarity, while preserving its maximum carat weight. Recklessly, however, you may be able to cut through a diamond rather quickly with an appropriately equipped tool.
