August Birthstone — Peridot

August's birthstone is the peridot — a vibrant green gemstone formed deep in the earth's mantle and occasionally found in meteorites.

Gemstone

Peridot

Colour

Vivid yellowish-green to olive green

Hardness

6.5–7 Mohs

Symbolism

Strength, healing, and prosperity

Peridot is one of only two gemstones formed in the earth's mantle rather than the crust (the other is diamond). It is brought to the surface by volcanic activity and has even been found in meteorites that have fallen to earth — truly a cosmic gemstone.

The ancient Egyptians called peridot the "gem of the sun" and believed it protected its wearer from evil spirits, especially at night. Cleopatra's famous emerald collection is now believed to have contained many peridots, as the two stones were frequently confused in antiquity.

Peridot is one of the few gemstones that occurs in only one colour — green — though the shade ranges from yellowish-green to olive. The most valued specimens display a rich, saturated lime green without brownish or yellowish undertones.

Jewellery Advice

Peridot's vivid green pairs beautifully with yellow gold for a warm, vintage aesthetic. White gold or platinum provides a more contemporary contrast. Its affordability makes it an excellent choice for larger, statement pieces.
