Peridot is the only gemstone that shares the same origin as diamond: deep in the Earth's mantle (a-la lava and meteorites), not in the crust. It's also one of the earliest recorded gemstones mined in history. It was the “gem of the sun” to Egyptians and to ancient Romans it deterred jealousy. On the topic of Rome, you'll see Dubini Jewellery's authentic ancient coins, set off by the juicy hues of peridot.
