A diamond NOT in oxygen, and/or (?) at high pressures can survive heat up to at least 3000C -- but it will burn in oxygen at 750C. But I think it would make it through the atmosphere pretty much intact. On impact a diamond will shatter ... so I suspect you would get a relatively shallow crater compared to regular meteorites.
