Rarely found in such a サ イ ズ also reveals it fine hexagonal growing marks on both pinacoid faces. Plenty of 2-phase inclusions can be spotted depending on the magnification you watching it. At the former base still some 白雲母 (Muscovite) is imbedded as well as a twin 結晶 crystal. An exceptional サ イ ズ d piece, from the Sakangyi pegmatite area.
