Rare Rock from Pikes Peak in Colorado
 
I have a few chunks of a blue green rock in the collection I inherited from my dad. When I first started KinesavaROCKS, I had NO idea what it was. But now I do. It turns out that it's a rock called Amazonite. According to Geology.com, "The gem was first named “Amazon stone”, after the Amazon River - although there are no known occurrences near that river". There are pictures of polished cabs there too. If you like turquoise or jade, check them out. The type I have is the "cross hatched pattern".
 
I was confused by this rock because it's not agate or jasper. I can recognize those rocks. According to Geology.com, "It is a variety of microcline, a potassium-rich member of the feldspar mineral group. Amazonite is commonly found in granitic pegmatites, which are coarse-grained igneous rocks." 
 
Geology.com also adds this note about making beautiful jewelry: 
 
"Today, amazonite is rarely used to produce mass-market jewelry. It is rarely used because manufacturers have difficulty finding an adequate supply of gem material and because jewelry customers are not familiar with amazonite. Amazonite is occasionally seen in one-of-a-kind jewelry made by a designer who specializes in using unusual gems.
 
This is one of the rocks in my dad's collection that other sites are selling at a fantastic price. I'm not. The nearest thing I could find online (Ebay) was 2 1/2 inches and priced at $165. They didn't show the weight. The "Mission Statement" of KinesavaROCKS is, "I'm not really in business. I'm just having fun with my dad's rocks."
