This lady is amazing.

Anyway, I love Peridot. Green is my favorite color.
Olivine is the same mineral:

"Definition: Olivine is a common rock-forming mineral group (magnesium-iron silicates), while peridot is the clear, transparent, and gem-grade variety fit for jewelry. [1] (https://ajluxe.com/blogs/jewelry-guide/olivine-vs-peridot)Appearance: Most olivine is opaque, fractured, or a dull, dark green found in rocks. Peridot features a bright, transparent yellow-green hue. [1] (https://www.gia.edu/peridot)"

Hawai'i Island has a beach with olivine in place of sand. It's beautiful.

Papakōlea Beach

PSA, The hike is 2 mile by foot, or you can rent a Jeep, and the rock climbing to get down to the beach itself is difficult, so you shouldn't attempt it if you have any bone, muscle, neurological, or similar limiting health conditions. Also, it is considered a sacred spot and nakedness is strictly prohibited.

So, love peridot and honorable mention to the Victorian jewels. I think Victorian's thought it they way they thought about Siberian amethyst.

Spinel.

I didn't know this was an August birthstone.

Red spinel is on my list of 5 favortite gems.
