Washington, D.C - Extraordinary American diamondson display in a new Smithsonian exhibitmined in the United States have recently opened at the National Museum of Natural History in the Smithsonian Institution.

The exhibition "Great American Diamonds" opened on Friday, June 10, and features four of the most notable stones that have been discovered in the United States.

This includes the "Freedom Diamond," which at the time of its discovery in the United States was the largest faceted diamond ever found there.

The Present Historical Artifacts On Exhibit

According to mineralogist Jeffrey Post, the museum's curator-in-charge of gems and minerals:

The cushion-cut stone was fashioned from a diamond that weighed 28 carats and was discovered at the Kelsey Lake Mine in Colorado in 1997.

It has since been mounted in a ring.

The exhibit at the Smithsonian also features the flawless emerald-cut "Uncle Sam Diamond," which weighs 12.4 carats and has a pinkish brown color.

The stone was discovered at the Crater of Diamonds mine in Arkansas in 1924.

It had been fashioned from a crystal that weighed 40.23 carats, making it the largest rough diamond ever discovered in the United States.

It was thought that the diamond had been destroyed, but it was discovered not too long ago in a private collection.

Since the last time, it was shown, more than half a century ago, "Great American Diamonds" will be the occasion for its return.

The Crater of Diamonds in Arkansas, which is now a state park and one of the only diamond-bearing sites accessible to the public around the world, and the Kelsey Lake Mine in Colorado are the only two diamond mines that have ever been operational in the United States.

Both of these mines are located in Colorado.

These two locations combined to produce tens of thousands of carats' worth of diamonds in their rough form; however, neither was able to achieve commercial success, and both ceased operations after fewer than ten years of operation.
