Peridot, Spinel, Sardonyx
Meaning & lore
We associate peridot with renewal. It was once worn as a protective talisman. For a present-day gift, its bright green can simply stand for a new beginning.
History & origins
Peridot has an ancient mining history on the Red Sea island of Zabargad. Red spinel was often mistaken for ruby, including the famous Black Prince’s Ruby. Sardonyx has a long tradition in carved ornaments.
Choosing a personal gift
August gives you room to choose by personality. Peridot suits someone who enjoys a fresh color accent; spinel offers more color choices; sardonyx brings graphic bands. If the wearer usually chooses neutral clothing, one small colored piece may be enough. For a more expressive dresser, use the birthstone as part of a layered combination.
Check sizing before choosing a bracelet, necklace or ring.
