Mineral: | Spinel
| Chemical Formula: | MgAl2O4 | Size: | | Weight: | | Transparence: | | Quantity: | | Origin: | Li Chaung Gyi mine, near Ohngaing (Ohn Gaing; Ohn Kai) village, north of Mogok, Burma (Myanmar) | This is a perfect example for a trapiche spinel pseudomorph after sapphire, as you can see the center is still a blue sapphire crystal surrounded by the more reddish spinel, which still shows the trapiche pattern of the former corundum. One side has been polished the other is a natural grown face .Very hard to find such specimens!
