Here is a collection of crafts that I couldn't categorize. There are many more examples and the next time I visit Mexico I will pick some more up.
This piece was purchased in a crafts store in Guaymas, Sonora. It seems to be a star of david made of plastic tubes filled with polished stones, a crystal mineral center and more polished stones and minerals wrapped with gold filled wire. It was so unusual I had to have it.
This copper/brass clock was purchased in Guadalajara. The round things are polished mineral stones. There is a vast selection of metal work art in this city. Most of it is too big or heavy to take back home.
