| Two fine tri-colored Tourmaline crystals imbedded in a massive quartz muscovite matrix. The crystals are absolutely unblemished and both disclosing a black base a blue part, followed by achroite section and ending with thin black layer. One crystal is also intergrown with cleavelandite. A great specimen from Afghanistan!!
