This was purchased by me from a reputable supplier located in Sri Lanka

Supposedly STAR RUTILE

but after much work by CGL-GRS

The results are SURPRISING !!

the Strong Metallic Sheen made standard testing inconclusive… so off it went to UBC

Results:
Hematite-Magnetite composition (wtf!)
no other examples are known or documented*
