50 Stars, 50 States, 50 Stones: What's Your State Gem?

 Independence Day! Fireworks, fun, apple pie, stars and stripes. 
50 stars, 50 states, 50 stones.

Each of United State of America has an official stone, gem, or mineral to represent their state. Thirty-five states have chosen a official state gemstone. Do you know any state stones? 

One of the first state gems I ever learned about was Florida's state stone. The Sunshine State's official gemstone is moonstone. Florida designated moonstone as the official state gem in 1970 to memorialize the American astronauts spaceflight and moon landing in 1969 from the Kennedy Space Center. 

Moonstone, a form of the mineral feldspar, is not found naturally in Florida. However our state stone, agatized coral, is found naturally in the state. 
Coral is the outside skeleton of tiny ocean animals which live in colonies attached to hard underwater surfaces. The tiny ocean animals, polyps, form a lime-stone like substance -- coral -- when their carbon dioxide combines with warm seawater. Agatized coral is 20-30 million years old. 

Florida's official tree is the beautiful Sabal palm, which grows everywhere in the state.The sabal palm tree has wonderful uses in landscaping, medicine, and food, and is the palm tree on our state seal. 

 We have awesome state flowers, butterflies and shells too. And our cool state animals include manatees, dolphins, and panthers!

And guess what the official drink of Florida is? Yes, orange juice of course!
.

To celebrate the 4th of July, I thought it would be fun to explore the 50 state's minerals, gems, and stones. Some states only have an official mineral, while other states have all an official mineral, stone, and gemstone. The following state listings are from  Geology at About.com. Check the "List of Official Gemstones" for links to images of the state gems.
