August birthstone necklaces feature two recognized gems: peridot and spinel. Peridot forms deep in the Earth's mantle and reaches the surface through volcanic activity. Its yellow-green color comes from iron content within the olivine mineral structure. Spinel occurs in reds, pinks, and blues, with a Mohs hardness of 8 compared to peridot's 6.5–7. Our collection includes 431 necklaces, each set in .925 sterling silver with natural stones. Prices range from $479 to $38569. Free shipping to all US addresses.

August has two official birthstones: peridot and spinel. Peridot has held this designation for centuries, while spinel was added by the American Gem Trade Association in 2016.
Peridot rates 6.5–7 on the Mohs hardness scale, making it suitable for necklaces and earrings with normal care. Avoid exposure to harsh chemicals and store separately from harder gems.
Iron within the olivine crystal structure produces peridot's characteristic yellow-green hue. Higher iron content results in deeper green tones.
