Quartz (variety smoky quartz).
EM27AC0: Quartz (variety smoky quartz)
A novelty at the Ste. Marie-aux-Mines 2015 Show. Excellent example in which the two directions of the smoky Quartz crystals have been controlled epitactically by the feldspar upon which they grew. They resemble multiple Japan law twins but they are not twins. This phenomenon is seen on similar specimens from the Erongo Mountains, Namibia, as described by John White in an article in Rocks & Minerals, vol. 87, Sept./Oct. 2012, pp. 459-462, but this one has a related combo of small species, classics from Malawi.

Quartz (variety smoky).
9MC14F5: Quartz (variety smoky)
One can see different crystals that have grown in various directions.
