Meteorites are solid pieces of space debris, often nickel and iron, that survive their journey to Earth. Adam’s friend finds them in Argentina’s Campo del Cielo craters, where their droplet shapes formed on impact; they are said to inspire confidence and strengthen the blood.

Tektites are natural glass created 15 million years ago by meteorite impacts, typically black. Moldavite, an olive-green variety, is only found near the Moldau River in the Czech Republic/Germany. Treasured for centuries as talismans and arrowheads, Tektites are rarer than diamonds, with only 50 tonnes ever formed on Earth.
