- Quartz, Apatite-(Caf)
- Cabinet, 11.5 x 6.0 x 5.2 cm
- Mawi pegmatite, Laghman (Lagman; Nuristan) Province, Afghanistan
An impressive, stout, water-clear, cabinet quartz crystal from the Mawi Pegmatite of Afghanistan and the Richard Hauck Quartz Collection. The base of the crystal rests on glassy, gem orthoclase variety adularia, smaller quartz crystals, matrix and partially hidden on the side, a gorgeous, 9 mm, gem, purple apatite crystal. The pristine, complete-all-around termination holds a striking inclusion, probably plates of tantalite or stibiotantalite. The back of the termination is lightly frosted and tinted with green chlorite. A most interesting, older quartz associaton piece from the well-known locale, especially with the gem apatite.
