What Are You Curious About?

I am from Wisconsin, staying in Winslow with girlfriend who is a nurse.. I just became interested in rocks and minerals and need help identifying some specimens…. thank you
Your specimens are three forms of quartz, in which the crystals are of microscopic size so you can’t see their shape.

 

 

 

 

 

 

 

 

This lightest colored specimen, is called chalcedony (http://www.quartzpage.de/chalcedony.html).

 

 

 

 

 

 

 

 

This pinkish-beige specimen is also chalcedony, with its pink-beige color coming from the presence of iron oxide.

 

 

 

 

 

 

 

 

This specimen, with the areas of darkly colored orange and red, is jasper, a variety of chalcedony (http://www.quartzpage.de/jasper.html).

Each of your specimens is typical of its type and could give you a nice beginning in collecting varieties of quartz.
