All natural diamonds have a similar hardness, however inside any diamond crystal there are 3 different hardness directions, with slight hardness differences.
As meteorite diamonds are natural diamonds, they have the same basic crystal structure, so the same hardness.

Basically, a diamond is a diamond is a diamond so the hardness does not depend on how it was formed. There are probably some minor variations in the physical properties of diamonds on a microscopic scale due to variations in the amount and types of crystalline defects but the bulk hardness should be very consistant. If you are talking about a single crystal diamond, then the physical properties will be different in different cyrstallographic directions.

Diamonds are a hardness of 10 on Moh's scale, meterorites have been found that included many miniscule diamonds with the same hardness, as well as black diamonds which don't follow the minerology of diamonds. I am not sure if this is what you are referring to, or if some company has started selling some type of imitation diamond called meteorite diamonds, if so they are not as hard as the real thing.

Meteorite diamonds ARE natural. There is no difference between these and the ones found on earth.
