Beryl with Musovite in Quartz; crystal 3.4 cm (both parts combine) x 1.7 cm, matrix 6.0 cm long; collector/photographer Arthur Koch

A nice but not terminated green beryl crystal with some accessory muscovite. I'm uncertain as to whether these are two separate crystals, or one that broke apart at some point during formation.
