Peridot And Sardonyx: The Two Least Known Birthstones


While we all know about the most common birthstone list — including the likes of emeralds, diamonds, and rubies — there are lesser-known options for many months that are every bit as beautiful. These stones can also offer a more affordable option for birthstone jewelry without sacrificing style or quality.

Peridot is Irish in origin but also found in other parts of the world, including Hawaii. The stone was once thought to need protection against evil spirits by night and was worn as an amulet or talisman. This green gemstone has excellent reflective qualities and is said to be “the gem of the sun” because it appears to glow when light shines on it. It’s an excellent choice for those who love earthy tones like green or brown but want something different than an emerald.

Sardonyx is a red, white, and black stone that blends well with both casual and formal attire. It has been used as a gem since ancient times, though its popularity has fluctuated over time, such as during Victorian England, where it was quite popular again after being first favored by civilizations such as Ancient Greece. While it may not be as famous today, sardonyx has maintained its timeless appeal for thousands of years because of how lovely this stone looks set into any type of jewelry piece.

Peridot And Sardonyx birthstones are two unique gemstones that can be chosen by those born in August. Let’s learn more about them.

Peridot and Sardonyx

August’s birthstones are peridot, sardonyx, and spinel. Peridot is the main birthstone for August. Spinel is a secondary alternative, and Sardonyx is an alternative. The word peridot comes from the Arabic ‘faridat,’ meaning gem. For thousands of years, this stone has been valued in many cultures, most notably in Egypt and China.

The name Sardonyx comes from the ancient Greek word ‘sardonios’, which means “of Sardis” (ancient city in what is now Turkey).


Peridot is an alluring green gemstone. It has been formed deep within the earth by the extreme heat of volcanoes and found its way to the surface as magma cooled, and other igneous rocks were formed.

Peridot is a gem with beautiful luster, making it hard to determine that it’s actually green. The deeper the color of Peridot, the more valuable it is considered to be.

In fact, it is sometimes mistaken for emeralds or even diamonds, but this amazing stone is easily distinguished by its color alone.

When researching peridot, you may come across another name for this gem, olivine (peridot’s Latin name). Olivine is sometimes still used today when referring to peridots that aren’t in their cut and polished form.

It’s also one of only two gems (the other being diamond) that are known to be found in meteorites from outer space! Peridot has been discovered inside meteorite craters in Arizona dating back nearly 50-million years ago!


Sardonyx is a gemstone that has a long history of use in jewelry. Sardonyx is a variety of quartz that is composed of alternating layers of sard (a type of chalcedony that is usually brown) and white onyx. The pleasant contrast between the two layers gives sardonyx the appearance of having thin lines or stripes running through it, which are parallel to the sides of the stone. Sardonyx can be cut into cabochons, beads, or faceted gems for setting in jewelry and other items requiring decorative stones.

The name sardonyx derives from “sard” (the Greek word for “yellowish-brown”) and “onyx” (the Greek word meaning “claw or fingernail”), which may refer to the color or translucent quality of some types of onyx. The name was given by Pliny, who wrote during Roman times that Sardonyx was used as an amulet in India because it protected its wearer from evil thoughts and temptations and granted good luck.
