A metallic shine on the surface of the rock, Small rounded pieces of stones on the surface (these are known as chondrules), A black or brown coating known as fusion crust (this is produced by the extreme heat of flying through the atmosphere), Small dents covering the surface of the rock (this is regmaglypt texture or thumbprints). In theory, small pieces of Mercury or Venus could have also reached Earth, but none have been conclusively identified. Stony meteorites do not contain iron materials (or very little, in the form of small-scattered grains), so they wont be pulled out by our magnet method. Surface.
