This Gemstone Was Once Declared “The Finest Ever Found In The U.S.”

NO LESS AN expert than George Kunz declared me “the finest precious gemstones ever found in the United States.” I have a natural, almost-exclusively blue beauty few other gemstones can match. But economics is no romantic. While there’s demand, supply has always been an issue (my warm geological upbringing means I tend to cling hard and fast to Mother Earth). So while, yes, consumers will pay a little more for top-of-the-line American goods, they won’t pay a huge premium when they can get a similar product from overseas. Chevrolet, PanAm, IBM PCs … I know how you feel.

Who am I?
