Today’s Exhibit of the Day? The Museum’s giant amethyst geode. Standing 9 ft (2.7 m) tall and weighing around 11,000 lbs (5,000 kg), it’s one of the largest specimens in our halls. How did this dazzling geode come to be? About 135 million years ago, the continental plates carrying South America and Africa began to separate. Magma poured out from fractures in Earth’s crust and large gas bubbles escaped from within the magma—becoming trapped in the rock as it solidified, forming cavities. Groundwater flowing into these spaces brought dissolved silica, which crystallized into quartz. Over millennia, most of these quartz crystals turned into rich purple amethyst. Spot this and other amazing specimens in the Museum’s Mignone Halls of Gems and Minerals!

Today’s Exhibit of the Day? It’s one of the largest amethyst geodes in the world! At about 13 ft (4 m) tall and 9,000 lbs (4,082 kg), this giant weighs about as much as three compact cars. It was born when molten magma poured from the Earth’s crust some 135 million years ago. While its dazzling purple crystals might catch your eye, this geode would have originally been composed of colorless quartz—its distinctive amethyst color deriving from millenia of natural radiation, heat, and trace contaminants. 

You can spot this geode, and other sparkly specimens, in the Museum’s Mignone Halls of Gems and Minerals. We're open daily from 10 am-5:30 pm! Plan your visit.

Are you sure?

(I can't think of a text for this bro. Let it be like this ;*)

(Hehehe, funny. I redrew this bro, added colors and something else that I didn't understand. But now I'm happy with the end result 😌)
