Luc Yen, Yenbai (Yen Bai) Province, Vietnam
Cabinet, 15.1 x 6.1 x 6.0 cm
This is a super-rich specimen of the silicate pargasite, uncommon in good crystals, from the locality that is better known for its spinels (in fact, many from this find were in combination with spinel crystals). The crystals on this specimen are seamlessly intergrown, so it is hard to give a single-crystal size - but the large cluster measures over 4 cm. 15.1 x 6.1 x 6.0cm[NOTE: (probably) not analyzed, could be fluor-cannilloite, see]
