There’s a mineral so rare that only one specimen of it has ever been found in the entire world.
It’s called kyawthuite (pronounced cha-too-ite), a tiny, golden-brown grain weighing just 1.61 carats (0.3 grams). At first glance, it might resemble amber or topaz—but this unassuming speck is priceless.
In 2010, gemologist Kyaw Thu purchased what he thought was a piece of scheelite at a market in Myanmar. After cutting and polishing it, he realized it was unlike any known mineral.
He sent it to the Gemological Institute of America (GIA), where scientists confirmed it was a naturally occurring form of bismuth antimonate (Bi3+Sb5+O4)—never before seen in nature.
