Mineral: | Espinela
| Fórmula química: | MgAl2O4 | Tamaño: | | Peso: | | Transparencia: | | Número de piezas: | | Origen: | La Mina de Pyan Pyit (Pein Pyit), al noreste de Mogok, estado de Shan, Birmania (Myanmar) | This is a true rarity for a spinel crystal, a very sharp round cyclic twin reminding on chrysoberyl twins. A real cyclic shape with two minor damages along the thin outline of the crystal, nevertheless this piece is another demonstration of the richness in variation of this mineral species. But those shapes rarely occurring, especially perfect cyclic. Furthermore you get good luster and medium to good transparency and strong red coloration. A must for a spinel collector.
