Hawaii's Volcano Is Literally Erupting with Gems – Green Peridot

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.

Wondering if this peridot stone is the same or similar to the pitdah in the Ephod: http://www.ancient-hebrew.org/articles_ephod.html

That’s a great question! Wonder if anyone here knows about gems?

What about Tarshish: also called Olivine (as in pitdah)?
Beryl, Lapis Lazuli, Amber, Jasper, Serpentine, Olivine, Flint

I just found this:

"A yellow-green, gem quality variety of the mineral olivine, peridot gets its attractive yellowish green hues from the presence of iron. Volcanic rocks (called basalt) are rich in iron and magnesium – two essential elements needed to create the gem. Hardened lava flows can be rich sources for peridot."
