At first I was thinking meteorite, too; however, this composition (regardless of which report you look at) is not correct (see:

) for any known type of meteorite.
The first report is for gems. If this is not a gem, but a mineral they cannot identify it using their listed means of identification (note: hematite is 5-6 on the Mohs Scale). Report two, from Fischer, appears to be hematite with several other trace minerals, not unusual. If the flag is an indicator of your location, hematite is the main iron ore in Brazil. The third report differs from the Fischer report considerably especially related to the iron content, as well as a few of the trace minerals.
Have you checked it with a magnet? Hematite is only slightly magnetic, if at all, and magnetite is strongly magnetic.
Titanium is a 6 on Mohs Hardness Scale and Chromium is a 9 on Vicker's hardness scale. It would seem based on your last report, with the high amount of Titanium and Chromium it would have tested higher on the Mohs scale than 5-6.
If it is hematite or magnetite, it should not have a refractive index because minerals do not allow light to pass through them. Yet the first report shows a refractive index. Hematite has a specific gravity of 5 and magnetite has a specific gravity of 4.9 - 5.2 ,where as your report says the specific gravity of this stone is 3.2. Considerably lighter weight.
Also you said that if you shine a flash light through it, it shows a dark blue color. Does this means that the light actually penetrates the stone? Or is it a reflection from the face of the stone?
It is all quite confusing because of the differences in the reports you are receiving
. Perhaps if there is a university near you with a Geology Department you could get them to check it out for you.
