August birthstone bracelets center on peridot, a yellow-green gem that has represented the month since the American Gem Society formalized the modern birthstone list. At SilverRush Style, we set natural peridot in .925 sterling silver, so the stone stays the focus. This guide covers what makes peridot worth wearing, how to size a bracelet correctly, and how to care for it after 2026.
What Peridot Actually Is
Peridot is gem-quality olivine, a magnesium iron silicate with the formula (Mg,Fe)2SiO4. The iron content is what produces the signature green, ranging from a light lime to a deeper olive tone. Unlike many colored stones, peridot is idiochromatic, meaning the color comes from a core element of its chemistry rather than a trace impurity.
The stone measures 6.5 to 7 on the Mohs hardness scale. That places it below quartz and well below sapphire, so a peridot bracelet needs a bit more care than an amethyst or topaz piece. It also has a refractive index of 1.65 to 1.69, which gives faceted stones a soft double-refraction sparkle under direct light.
Most commercial peridot today comes from three sources: the San Carlos Apache Reservation in Arizona, the Sagerat and Suppat mines of Pakistan’s Kohistan region, and Myanmar’s Mogok Valley. Historic Egyptian peridot from Zabargad Island in the Red Sea is largely mined out, though older stones still circulate through estate channels.
Choosing an August Birthstone Bracelet
Peridot pairs well with cool metals because the green reads clean against a silver-white background. Our sterling silver jewelry uses .925 alloy, which is 92.5% pure silver mixed with 7.5% copper for structural strength. This matters for bracelets because the wrist sees more knocks than a pendant or earring.
Setting style changes how the stone wears day to day. Bezel settings wrap the girdle of the peridot in a silver rim, protecting the softer edges from chips. Prong settings expose more of the pavilion, letting light enter from below and brightening the color, though they leave the stone more vulnerable during activity.
Chain style is the next decision. Curb and figaro chains sit flat and layer well with watches. Cable and rolo chains drape rounder and suit stacked bracelet looks. For faceted peridot stations, a shiny finish reflects more light through the stone; for cabochon peridot, a matte or oxidized silver reduces glare and lets the stone’s saturation carry the piece.
Getting the Size Right
Measure the wrist with a soft tape just above the wrist bone, then add half an inch for a snug fit or a full inch for a relaxed drape. Standard women’s bracelets run 6.5 to 7.5 inches, and most of our August pieces include a one-inch extender chain to fine-tune the fit. If you fall between sizes, choose the longer length; a bracelet that sits slightly loose is more comfortable than one that binds.
Peridot Beyond the Birthday Gift
The stone has a longer history than the modern birthstone list suggests. Egyptian records from the 4th century BCE describe mining on Zabargad, and many stones long identified as emeralds in medieval European church treasuries were later reclassified as peridot. The Cologne Cathedral’s Shrine of the Three Kings holds one such example, containing 200 carats of peridot originally cataloged as emerald.
Peridot also has an extraterrestrial provenance that few gems can claim. Olivine crystals appear in pallasite meteorites, and gem-quality peridot has been faceted from meteorite fragments found in Argentina’s Esquel field. Terrestrial peridot forms deep in the upper mantle and reaches the surface through basaltic lava flows, which explains why the Arizona and Hawaiian deposits sit in old volcanic terrain.
Beyond August birthdays, peridot is the traditional gift for a 16th wedding anniversary. It also works as an alternative to emerald for people who want green without the price jump; a well-cut two-carat peridot generally runs a fraction of an equivalent emerald while offering better clarity, since peridot is typically eye-clean where emerald usually shows inclusions.
Caring for Sterling Silver and Peridot
Peridot is sensitive to sudden temperature changes and to acids, including sweat over long wear. Take the bracelet off before showering, swimming, or exercising, and avoid ultrasonic and steam cleaners, both of which can fracture the stone along internal stress lines. Wipe it after wearing with a soft cotton cloth to remove skin oils.
Sterling silver tarnishes when sulfur in the air reacts with the surface. Store your bracelet in an anti-tarnish pouch or a zip bag with the air pressed out, and keep a silica packet in the storage box if you live in a humid climate. Light tarnish comes off with a silver polishing cloth; heavier oxidation may need a silver dip, though never submerge the peridot itself since the chemistry can etch the stone.
For deeper cleaning, use lukewarm water with a drop of mild dish soap and a soft toothbrush around the setting. Rinse, then dry fully before storage. Check the prongs or bezel every few months by running a fingernail around the setting; any catch or lift means it is time for a jeweler to tighten the mount before you lose a stone.

We have been fitting sterling silver on real people since 2005, and we would rather answer a question up front than process a return later.
