A flight from San Jose, Costa Rica to the U.S. can take you over Lake Nicaragua and the double volcanic island of Ometepe. That’s the active Concepcion in the foreground with the dormant Maderas in the back.

Happy Valentine’s Day! This heart of stone was carried from the mantle to the surface and trapped in lava. The green mineral is olivine, which you may know as peridot. Cerro Mercedes, Costa Rica.

Red Beryl is one if the rarest gemstones on Earth and is found only in the Wah Wah mountains of Utah. Green beryl (emerald) is far more common.
