Recently, we were fortunate to take a family trip to Maryland, DC where we stopped at the Smithsonian Museum in Washington. This was a must-see – after all, who doesn’t love old dinosaur bones and interesting artifacts?  

We were most excited about discovering the granite  in the Hall of Geology, Gems and Minerals – this is what we work with every day! It was great to see our children get as excited as us about the natural stones we deal with every day at Regent Granite. 

Here’s a look at some interesting naturals stones and granite we discovered at our trip to the Smithsonian Museum.
