There are no tetrahedral crystals.
The shape of chloromethane is tetrahedral.
The shape would tend to be trigonal pyramidal. An example would be ammonia, NH3.
Herkimer "diamonds" are twinned quartz crystals and so could be recognised by crystal shape alone. also, diamonds superior hardness would make it stand out from a Herkimer "diamond" if you were to test the two against a beryl or corundum crystal.

Tetrahedral
Four atoms bound to a central atom with no lone pairs
Four atoms bound to a central atom with no lone pairs
the interactical shape of its form would be the growth of it.
The molecular shape of XeF4, or xenon tetrafluoride, is square planar. Its molecules are located in a square's corners around an atom in the center in a single place.
