The birthstone for August
Peridot, the birthstone for August, has fascinated jewellery enthusiasts since ancient times. This captivating gem always displays shades of green but with intriguing variations, depending on its source.
Peridot is the gem variety of the mineral olivine. It’s a magnesium iron silicate and has a hardness which ranges between 6.5 and 7. Sought after for its captivating colour, resulting from a prevalence of magnesium over iron, olivine is abundant in basalts and peridotite bodies – types of igneous (volcanic) rock.
Where is peridot found?
According to the American Gem Society, an estimated 80 to 95 percent of the world’s peridot supply is found in San Carlos Apache Indian Reservation, Arizona. Aside from the US, other significant deposits are found in the Himalayas, Myanmar, Pakistan and Zabargad Island, Egypt.
Smaller deposits are also found in Australia. Mortlake in Victoria is known for its olivine deposits which formed up to 80 kilometres below ground before being brought to the surface during volcanic eruptions.
Most surprisingly, and incredibly rarely, peridot has been found contained in meteorites that have fallen to Earth; these are known as pallasites.
Peridot’s colour range
Peridot’s colour can range from vibrant green to yellow green with hints of brown. The superior hue is considered pure green without any other colours present.
As pure green stones are considered rarer, these generally come with a higher price tag – especially if they are a larger carat size with no eye-visible inclusions in the clarity.
The majority of peridot jewellery on the market are more yellow green, however as long as they are intense in colour, they still make perfect jewellery pieces for those with birthdays in August.
How to care for peridot
Peridot is not only a stunning gemstone but also a delicate one. With a hardness on the Mohs scale ranging from 6.5 to 7, it makes peridots comparable to quartz gems. However, they are still susceptible to scratching and are somewhat prone to stress fractures.
It’s recommended to clean the stones only with a soft brush, mild detergent, and warm water. Peridots also have some sensitivity to acids, even those found in perspiration. Peridot jewellery should not be worn during rigorous exercise and should be removed before bed.
Peridot's captivating colour and unique characteristics make it an enchanting gemstone that continues to mesmerise gem and jewellery enthusiasts worldwide.
