Quartz Crystal Gemmology Quiz

Do you know that although quartz is the most commonly found crystal, it also exhibits the most complex crystalline habits. The three basic habits are Prismatic, Equant and Acute Rhombohedral.

Well here is a small challenge for gemmology students or quartz crystal lovers . There are pictures of several quartz crystals below whose termainations can be seen in some of the pictures. Can you identify which of these faces are:

a. Prism
b. Major Rhombohedra
c. Minor Rhombohedra
d. Trapezohedron
e. Trigonal Bipyramid

I will publish the answer in the July 2005. Note that some of the faces may not be present in these cystals.
