Luster (spelled lustre in our British textbook) is the sheen reflected from the mineral's surface.  It is not a color but is the way the mineral appears to us.  That is, the mineral may be non-metallic looking and be one of the following: pearly, waxy, vitreous (like glass), adamantine (like a diamond), earthy,  or the mineral may appear metallic (like a metal).  So the major subdivisions are metallic or non-metallic.  Metallic mineral luster implies it looks like some kind of metal, but remember that there are differences in metals and that the designation is somewhat arbitary and subjective.  For instance, there is a catagory called submetallic, but what that really means is hard to say (though if you were shown an example you might agree with the designation).

The wide variety of non-metallic lusters is complicated.  You need to have the comparison materials in mind.  Waxy for instance might apply to some opals and amber, but other specimens might appear resinous or vitreous.

Again, tables might be arranged by luster, but usually this is only done by making two lists, metallic and non-metallic.  The breaking of all minerals into one of these two groups is important for geological studies, but less so for gems where almost every mineral is non-metallic.
