Occasionally I encounter a crystal cluster with two faces. Such is the case with this cluster.
Rarely do you find a specimen with two different crystal structures on opposite sides of the same rock. Here we have calcite on one side and quartz on the other.
Side one is loaded with Dog Tooth Calcite. These are crystals that are wide at the base and taper down to a point, similar to a canine tooth. (hence the name)
Side two has tiny quarts crystals. Quartz is commonly known for it's long rod like structure that suddenly comes to a point at the end.
I also discovered a couple pyrite cubes while exploring the quartz side.
The matrix (host rock) that the crystals grew on is also a curiosity. It's a shiny silver grey material resembling galena, but I can't be sure. upon closer examination, It could be bornite.
In a couple instances, the matrix was lifted up onto the tip of the growing crystal
Really cool! The 3D effect I get when looking through the scope is phenomenal. I only wish I could show on these posts what I truly see. The last image is a crystal point coming directly at you.

It seems like pyrite and quartz are often found together. I remember more than once as a kid thinking I'd found gold. Is there any specific mineralogical reason for that?
I've been trying to recreate the 3d effect myself, so far no good results. I have a camera mount on my stereoscope, so I've been trying to shift the specimen slightly between two images and then animate them or set them up side by side. I may try to take manual images through each eyepiece next. Let me know if you have any luck with this. So much of the coolness of a stereoscope is lost in 2d.

Yes it is. My stereoscope is not an expensive one and the camera mount only goes on one eyepiece. I'm checking with some friends that are into macro-photography and they are going over some ideas. The real issue is having double lenses. Not sure that there is a way to project that.
