Peridot – One of Three August Birthstones

“Wear a Peridot or for thee,
No conjugal fidelity,
The August born without this stone,
‘Tis said must live unloved, alone”
It may surprise you to learn that August has three birthstones: sardonyx, spinel, and peridot. Sardonyx is the original August birthstone with peridot and spinel added later. Spinel didn’t become an August birthstone until 2016! Yet, perhaps because of its vivid and distinct green color or because it is so rare to find on the Earth’s surface, or simply because it maintains its color so well, peridot has become August’s primary gemstone.
How to buy Peridot
If you’re looking for August birthstone jewelry and have decided on the peridot, or simply love its beautiful lime-green hue, there are a few things to keep in mind:
- The finest peridots have no inclusions visible to the naked eye (although you might see some dark spots if viewed through a microscope).
- The highest-quality peridots are a lime-green color without any traces of brown or yellow.
- Smaller peridot sizes are relatively affordable, but larger stones get expensive.
- Peridot has a very high double refraction (refraction is the bending of light as it passes in or out of a gem; the higher the refraction index, the higher the stone’s brilliance), so a good way to check if it is real is to hold it against a light. If there is no double refraction, it is most likely fake.
- Peridots look best with yellow or rose gold metals rather than white metals like white gold.
