These are the sort of crystals we will hopefully find. The biggest (in the back) is about two inches long. The have nice sharp crystal faces are are all nearly complete and doubly terminated. Most of the imperfections on these crystals are contact points. Places the crystal grew -in contact - with the pocket or other crystals. You will find lots of broken crystals and fragments, but this is what you strive to find.
This is a close up view of a rhombohedral (pyramidal) faces. These are little bumps called growth hillocks. They are fairly common on quartz crystals and especially those from Diamond Point. They are best seen when light is reflected from the rhombohedral faces. Here is a link to some more information on quartz crystal faces. http://www.quartzpage.de/crs_forms.html
Amethyst crystals have also been found at Diamond Point. Although not common, they are always a welcome find. This picture also shows where the crystals were originally found, i.e., in pockets within the limestone. Just by wandering around the forest you may find a few crystal loose at the surface. These crystals were formed in the pockets, but being more durable than the limestone and calcite (also found in the pockets) they survive weathering and erosion to accumulate at the surface. Obviously, there were more common years ago, but by careful searching, the collector will be able to find some.
This is a clear quartz crystal in a pocket with calcite crystals. Normally it is better to collect "matrix" specimens, although the matrix (limestone) in this sample is just a little too big. This one was obtained by breaking a limestone boulder. (Bring a big hammer.)
Keep your eyes open for these little critters. This is the GREATER SHORT-HORNED LIZARD - Phrynosoma (Tapaja) hernandesi. They are harmless and interesting to look at and photograph. This one looks a little irritated with me. (I think they always look a little bit miffed.)
