If you go to the Smithsonian Gallery, you will certainly find an eight-thousand-pound swelling of quartz.
This unique rock, called the Berns Quartz, was discovered in a mine in Arkansas in 2016, as well as it is currently in cost of inviting people to the Smithsonian as component of the National Gem and also Minerals Collection.
A piece of clear quartz is just $14 on Amazon.com, but a clear collection this large is unusual and valued in the millions.
The cluster most likely formed after the Ouachita Mountains began to deteriorate millions of years back, revealing the Berns Quartz, amongst other deeply-buried veins of crystals, within the Arkansas chain of mountains.
