Sillimanite : Al₂[O\|SiO₄]
	Mogok, Sagaing District, Mandalay Division, Burma (Myanmar) Sillimanite. Vasco Trancoso collection and photo. Size: 2.0 x 0.5 x 0.3 cm Sillimanite is a high temperature and high pressure aluminum silicate found in metamorphic rocks. Transparent crystals are called "fibrolite" by gemologists. This is a fine elongate crystal with a bit of rounding. The edge rounding likely represents resorption into the ...
