the bad month of December

Between being sick, and snowed in, I've barely let the house this month.  Now I have to venture out and fill a rock order.  Fortunately, my worst cold in years might be going the other way.  On the dark side, it was thirty below this morning. 

The next group of minerals to be considered are the single chain silicates, also known as pyroxenes.  This group includes several well known gemstones. 

 Here are some of the single chain silicates:  diopside, enstatite, hedbergite, aigote. ju[ersthene, aegerite, johannsenite, rhodonite, jadeite, wollastonite, spodumene, chrysocolla.  How many do you recognize?Quite a few, I would imagine.  This is a major group of rock forming minerals.
