Hawaii's Volcano Is Literally Erupting with Gems – Green Peridot
Hawaii's Kilauea volcano has been fiercely erupting for well over a month. Now, residents are finding little green gems that have fallen out of the sky during Kilauea's eruption.
The green gems are olivine crystals, a common mineral found in Hawaii's lava. At jewelry quality, the mineral is called peridot. As the volcano erupts, it blasts apart molten lava, allowing for green olivine minerals to be separated from the rest of the melt and fall as tiny gemstones.
