The birthstone for August is peridot. Here are some fun facts about peridot:
Peridot is always green, because it is idiocrhomatic, meaning that its color is because of its chemical composition. If there are any impurities in the chemical composition for other stones, that usually gives you color. But for peridot, it makes it something other than peridot.
Peridot forms in the Earth’s mantle. The only other stone to do so is diamond. Peridot and diamond come to the surface with volcanic eruption or earthquake. Peridot is commonly found in the US (Arizona) and China.
Olivine is the mineral form of peridot (it may be opaque and not a crystal, for exmaple). It is found on Mars.
Peridot was more popular than emerald in ancient times because they valued color more than transparency. Peridot held its color even in candlelight, unlike emerald, which needed much more light to still show as green.
I peridot! It’s such a serene and peaceful color gem
I enjoyed reading those fun facts! I was so surprised to learn peridot’s green color does not go through an enhancement process! I’ve came across foggy peridot stones before, so I’ve learned to be very finicky about them
