Name(s) in local language(s): Massiccio Dora Maira, Cuneo, Piemonte, Italia
 
Very high pressure metamorphism of Mg-rich pelites, at depths over 100 km, have created this very unusual pyrope-coesite-quartzite, now exposed in the Western Alps. Famous for its (nearly) colorless, very pure pyrope (over 95% pyrope molecule) as crude crystals up to coconut size. High-pressure phases like ellenbergerite and coesite are preserved only as inclusions in the pyrope, not in the surrounding matrix.

The main composition of the quartzite is: quartz, phengite, talc, kyanite, pyrope.

Individual localities are Case Parigi (Case Paris) and Case Ramello.
