Mineral: | Espinela
| Fórmula química: | MgAl2O4 | Tamaño: | | Peso: | | Transparencia: | | Número de piezas: | | Origen: | La mina de Li Chaung Gyi cerca de aldea de Ohngaing (Ohn Gaing; Ohn Kai), al noreste de Mogok, Birmania (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!
