Chromium(VI) oxide peroxide, CrO5
Mixed valence species, such as Cr8O21
Chromium(III) oxide is the inorganic compound of the formula Cr2O3. It is one of principal oxides of chromium and is used as a pigment. In nature, it occurs as the rare mineral eskolaite.
Also, I believe the structure of the crystals are different - CrO2 is more rounded than diamond, and I've heard CrO2 gives a smoother feel to the edge because of this. However, for the same reason it's also a slower cutter than diamond. Similar idea to the garnets in a coticule, I believe, which are shaped like a soccer ball with every edge at an obtuse angle to the others.
Chromium is a chemical element which has the symbol Cr and atomic number 24. It is the first element in Group 6. It is a steely-gray, lustrous, hard metal that takes a high polish and has a high melting point, also odorless, tasteless, and malleable.
