The two traditional August birthstones are the stunning peridot and spinel. Peridot is a yellow-green gemstone while spinel comes in various colors, often mistaken for other gems.
The month was named August in 8 BC after Roman Emperor Augustus Caesar, chosen by him to commemorate his past triumphs during August. Previously, it was named Sextilis, meaning “sixth,” when March began the year.
Many ancient festivals held during August involved harvests, safety, and prayers for the changing season to be peaceful.
August is associated with abundance, protection, and regeneration. Many of these traits are seen in August birthstones, too!
Today, we’ll dive into the history, meanings, powers, and value factors of the August birthstones peridot and spinel. We’ll also touch on some alternative birthstones and gift ideas!

Why are there 3 birthstones for August? For one, not all lists have three August birthstones. Secondly, birthstones have changed over time.
So, when did the August birthstone change?
Way back in the 1st and 5th centuries AD, early birthstone lists were inspired from Biblical lists of 12 gemstones. In these lists, the August birthstone was either carnelian or sardonyx.
Tiffany & Co released a pamphlet of birthstone poems in 1870 with sardonyx for August.
The first standardized list was created by the National Association of Jewellers (now Jewellers of America) in 1912. This list had sardonyx as the primary August birthstone, with peridot as an alternative.
In 1937, the National Association of Goldsmiths released a list with reversed priority — peridot primary, sardonyx alternative.
Later, the 1912 list was altered when the American Gem Trade Association collaborated with Jewellers of America. One of the changes was adding spinel for August in 2016.
That’s why we’ll focus on peridot and spinel in today’s guide.
With the birthstone history covered, we’ll dive into these gem’s individual history next.

Peridot’s history begins in ancient Egypt.
The earliest records of peridot mining go back to 1500 BC, when ancient Egyptians found the August birthstone on Topazios (now called St. John’s Island or Zabargad).
Cleopatra believed peridot was protective against evil forces, and Egyptian priests drank from peridot-encrusted goblets to communicate with gods of nature.
Ancient Hawaiian legends connect peridot to Pele, the goddess of fire and volcanoes. Some myths say peridots are Pele’s tears. Others claim the birthstones are healing gifts from Pele.
Historically, peridot has been mixed up with many stones.
Another centuries-long confusion was between peridot vs emerald.
In fact, ancient Romans called peridot “Evening Emerald.” Some historians believe Cleopatra’s emerald collection was actually peridots.
Other famous examples of peridots mistaken for emeralds include:
The 200-carat gems on the Three Holy Kings shrine in Germany’s Cologne Cathedral
French Empress Joséphine Bonaparte’s necklace gifted by her Emperor husband, Napoleon — Napoleon happened to be born in August!
Yet no gem takes the title of “imposter” more than spinel.

Historically, “ruby” was often used for all red gemstones. When imported rubies were introduced to Europe in the Middle Ages, spinels from Afghanistan were labeled “balas rubies.”
Until the 1800s, European royals were vying for “Balas rubies,” even though some medieval scholars categorized them as distinct from true rubies.
Notable examples of spinels mistaken for rubies are the Black Prince’s Ruby and Timur Ruby.
The Black Prince’s Ruby was first owned by 14th-century Granada prince Abu Said Faraj. Eventually, the “Black Prince” Edward of Woodstock got it. It eventually became the centerstone of the Imperial State Crown used at Queen Victoria’s 1838 coronation.
The Timur Ruby (pictured above) was named after Timurid ruler Timur, mistakenly believed to have taken it while invading Delhi in 1398. Ownership passed among various Mughal and Sikh rulers until the East India Company took it in 1849.
They gifted it to Queen Victoria in 1851. She had it set in a Garrards necklace in 1853.
Luckily, spinels have slowly gained recognition as beautiful gemstones and versatile August birthstones.

Starting with peridot, this August birthstone is a magnesium iron silicate and the gemstone form of olivine (sometimes called chrysotile).
Today, most peridot crystals come from Arizona (USA), Myanmar, Pakistan, and Sri Lanka. Myanmar and Egypt produce the largest facetable peridots.
Moving on to spinel, this August birthstone is a magnesium aluminum oxide in the spinel subgroup of isometric aluminum oxides. Other stones in this group include magnetite and gahnite, but spinel is the only group member commonly used in jewelry.
Although spinels form in host rocks, miners usually find them in alluvial deposits, where water has eroded the rock and brought the gems downstream, often rounding the crystals along the way.
Spinel birthstones are found worldwide, but the main sources for gem-quality specimens are Afghanistan, Myanmar, and Sri Lanka.

Peridot is one of few gemstones defined by its green coloring, but this August birthstone’s colors actually range from pure green to yellow-green to brownish-green.
Why is the August birthstone green? Peridot is idiochromatic, so its green coloring comes from the ferrous iron (Fe2+) present in its mineral formula.
Ferric iron (Fe3+) can lend yellow undertones, while chromium can brighten the green hues. The ideal iron content is 12 to 15 percent — anything higher leads to browner, less valuable colors.
Many peridot gems are identified by their origin:
Changbai, China: Bright lime green
Hunan, China: More yellow-green
Myanmar: Bright medium to dark green & oily
Sondmore, Norway: Paler lime-green
Kashmir, Pakistan: Apple- or lime-green, gold undertones
Zabargad, Egypt: Rich medium-green
As far as optical effects, peridots very rarely exhibit chatoyancy (the “cat’s eye” effect) or asterism (the “star” effect). Additionally, this August birthstone’s high birefringence can result in facet-doubling and fuzziness.
Pictured above: Faceted violet spinel
The spinel August birthstone colors are vast, including almost every color in the rainbow and shades in between. Most spinel gemstones are red, pink, orange, lilac, and blue.
The impurities behind this birthstone’s colors are:
Chromium, ferric iron, and/or vanadium – red, magenta, purple
Cobalt and/or ferrous iron – blue, bluish-purple, purple
Vanadium – orange, orange-red
Ferrous & ferric iron charge transfer – green
Magnesium aluminum oxide – black
Certain impurities and colors have led to different varieties and trade names — read more about these in our Spinel Info Guide.
Some Myanmar spinels display asterism. More rarely, spinels can be color-changing, from grayish-blue or violet in sunlight to purple or reddish-violet under incandescence.

The quality of peridot and spinel birthstones is graded on color, clarity, cut, and carat weight, along with any treatments done.
Peridot: Pure, vibrant grass-green peridots are usually most valuable, followed by moderately saturated yellow-green coloring. Yellow undertones are most common. Brown undertones lower value.
Spinel: In order, the rarest and most valuable spinels are red, cobalt-blue, bright pink, and bright orange.
More affordable (but still beautiful) options are shades of purple like lavender, bluish-purple, and violet. Higher saturation is rarer and more valuable.
Clarity describes the degree of visible inclusions, which lowers a stone’s transparency and value. Both peridot and spinel have Type II clarity, meaning high-quality specimens are usually eye-clean (no visible inclusions without magnification).
Peridot: Under magnification, many peridot gems have “lily pad” inclusions, making the stone harder to cut. Fewer inclusions are ideal.
Spinel: Many spinels have intriguing, distinctive rows of octahedral crystal inclusions. Aligned rutile needles cause the valuable “star” effect.

Peridot: Gem cutters must consider peridot’s birefringence, clarity, and color when choosing faceted cuts. Checkerboard cuts can mask inclusions, but round, pear, and oval brilliant shapes are most popular.
Spinel: The most common faceted spinel cuts are oval, round, and cushion shapes, which maximize spinel’s brilliance. High-quality spinel material may be cut into non-calibrated sizes.
Peridot: Gem-quality peridot rough is rarely over 3 carats, with most gems under 1 carat. The price-per-carat for gems over 3 carats is significantly higher.
Spinel: Most spinels today are under 5 carats. Gems over 5 carats have significantly higher price-per-carat rates, especially blue, red, and pink spinels.
Peridot: Treatments are rare for peridot, though some are metal-foiled to enhance color and durability.
Spinel: Most natural spinels are untreated. Rarely, some are heated and fracture-filled for better clarity. Various diffusion treatments may be done to create artificial colors like cobalt-blue.

Peridot and spinel aren’t only beautiful — these August birthstones are also significant metaphysically.
Historically, peridot was often connected to light and protection.
Ancient Egyptians called it the “gem of the sun,” and wore it as protection from “terrors of the night.” Some ancients thought peridot came from a solar explosion.
The 16th-century writer Heinrich Cornelius Agrippa claimed holding peridot to the sun would make it reflect a golden star that healed breathing problems.
Some believe peridot dispelled nightmares, madness, and memory loss. Others claim its “inner radiance” brought mental clarity and spiritual awareness.
Today, the peridot August birthstone symbolizes renewal, protection, and harmony.
For spinel, this August birthstone’s meaning is tied to love and rejuvenation.
As healing stones, spinels are believed to promote passion, devotion, and happiness, along with decreasing anxiety and balancing emotions.
Metaphysical nicknames for spinel include:
Stone of Hope
Stone of Joy
Stone of Revitalization
Stone of Immortality
Spiritually, some use spinel for boosting intuition and communication with celestial realms. People in Myanmar say spinel crystals are nat thwe, meaning “polished by the spirits.”
The August birthstone is also used for opening the root chakra and re-energizing the wearer.
Rising awareness around conflict diamonds may lead conscious consumers to wonder about the ethics and sustainability of peridot and spinel mining.
Partial responsibility is on jewelers, who can choose to buy from smaller, independently owned and vetted mines who are transparent about their supply chain. The other responsibility is on buyers, who can choose to only buy August birthstones from vetted, transparent jewelers.
Luckily, roughly 80 to 95 percent of peridot gem material is exclusively mined by Apache tribe members on the San Carlos Apache Reservation in Arizona, USA, an independent operation open to visitors.
Many jewelers opt for spinels from Tanzania and Sri Lanka, where mining practices are transparent and not associated with human rights violations.
Many buyers have turned to synthetic versions of August birthstones, which have the same chemical and physical properties as natural material but are lab-created.
In fact, synthetic spinels are among the most common lab-created gems. Synthetic peridot is less common.

Spinel itself is often a simulant of other gems, but peridot has many affordable simulants, like:
Astrologically, what is the birthstone for Virgo in August? Among the traditional birthstones, earth-sign Virgos may prefer a grassy-green peridot.
What is the birthstone for Leo? August-born Leos might prefer the passion of spinel, especially fiery red spinel.

Spinel and peridot may seem different, but they’re more alike than you’d think. Both represent light and renewal, and both have been mistaken for other gems. Along with sardonyx, these August birthstones offer a range of possibilities for celebrating anyone born at the end of summer!
Svaki mjesec u godini ima svoj rođendanski kamen, a neki su sretni da ih imaju više! Kolovoz je jedan od tih mjeseci i jedan od samo tri mjeseca u godini s tri jedinstvena draga kamenja. Koji su rođendani za kolovoz?
U ovom vodiču za rodne kamene u kolovozu dijelimo značenje, povijest i simbolizam iza tri prekrasna dragulja.
Jeste li spremni naučiti o kamenčićima za rođenje u kolovozu? Nastavite čitati dok idemo niz popis.
Tri rodna kamena za kolovoz su Peridot, Spinel i Sardonyx. Iako dijele isti mjesec rođenja, svaki od ovih dragulja je potpuno jedinstven. Istražimo!
Peridot je dragi kamen koji varira u boji od žutozelene do zelene limete. Svoju boju zaslužan je mineral zvan olivin, a zanimljivo je da zato ovaj dragulj dolazi samo u zelenoj boji.
Naravno, na zelenom ćete spektru naići na razne nijanse i nijanse. U konačnici, boja peridota ovisi o tome koliko je željeza prisutno u kristalnoj strukturi dragulja.
Od svih varijacija peridota, duboko maslinasto zelena je najcjenjenija i najvrjednija. Razumljivo, s obzirom na to da izgleda lijepo kada se stavi u komade nakita!
Olivin prevladava u lavi koja se izlijeva u Zemljin plašt. Kako se lava stvrdne, izdiže se na površinu Zemlje. Olivin također putuje na Zemlju s meteoritima iz svemira. Prilično uredno, zar ne?
Dakle, što znači peridot?
Povijest i simbolika kolovoškog rodnog kamena peridota su fascinantni. Peridotovo podrijetlo seže do Topaziosa, otoka u Crvenom moru, koji datira iz 2. stoljeća pr. Naziv, peridot, dolazi od faridat, arapske riječi za dragulj.
Kao zaštitni kamen, drevni ljudi su se ukrašavali ovim zelenim draguljem za borbu protiv zlih duhova i noćnih strahota.
Stoljećima su ljudi miješali peridot s drugim dragim kamenjem poput topaza i smaragda. Na primjer, katedrala u Kölnu u Njemačkoj ima sveto Svetište Tri kralja ukrašeno peridotom. Međutim, većina je vjerovala da su dragulji smaragdi dok im nije dokazano suprotno.
Peridot je jedan od tri kolovoška kamena rođenja, a ujedno i slavljenički dragulj 16. godišnjice.
Pogledajmo spinel, najnoviji službeni kamen za rođenje u kolovozu.
Drugi kolovozov rodni kamen je šareni spinel . Iako postoji stoljećima, tek je nedavno postao prepoznat kao dragi kamen trećeg kolovoza.
Sama riječ prevodi se s latinske riječi za trn, spina. Spinel je zabavan rodni kamen jer dolazi u nizu boja, od narančaste preko ljubičaste do ružičaste! Kao što možete zamisliti, ovo je vrhunski rodni kamen u kolovozu jer ga možete personalizirati tako da odgovara vašoj omiljenoj boji.
Poput peridota, ljudi često miješaju spinel s drugim draguljima, uključujući rubine, unatoč njihovim kemijskim razlikama.
To je zato što crvena spinel izgleda zapanjujuće slično dragom kamenu rubin. Budući da su boje špinele tako živahne, plavi spinel se često zamijeni s plavim safirnim draguljem.
Spinel dolazi iz nekoliko izvora, uključujući Šri Lanku, Tanzaniju, Vijetnam, Mjanmar i Pakistan. Ono što spinel čini tako lijepom je njegova bogata i živahna boja. Svaka boja ovog prekrasnog dragulja bogato je zasićena, od živopisne ružičaste preko bogate crvene do kraljevsko plave.
Već generacijama spinel nudi prirodno liječenje upala i krvnih bolesti. Također, ljekovita svojstva spinela pomažu u ublažavanju negativnih emocija te pospješuju sklad i mir.
Od sva tri kolovozna kamena rođenja, Sardonyx je najstariji, star više od 4000 godina. Drevni kolovozov kamen, Sardonyx, kemijski se sastoji od dvije varijacije kvarca: sarda i oniksa.
Spojite to dvoje i dobit ćete Sardonyx! Ovaj dragi kamen star je koliko i sama civilizacija. Zapravo, tijekom Rimskog carstva, Sardonyx se koristio u prstenovima s pečatima koje su nosili plemstvo i kraljevske obitelji. Ti su prstenovi služili kao pečati ili potpisi istaknutih ličnosti za potpis, pečat i isporuku svojih pisama.
Sardonyx je jedinstven kamen za rođenje zbog svojih uzoraka i boja. Tijelo dragulja pojavljuje se u nijansama smeđe, crvene i narančaste boje, prošarano bijelim ili crnim prugama od oniksa.
Sardonyx je djelovao prekrasno jer se vrući vosak lako zalijepio za njega, što ga čini glavnim izborom za prsten s pečatom. Još jedna sjajna značajka Sardonyxa je da je to izvrstan materijal koji se koristi za rezbarenje kameja za nakit.
Potječe iz Brazila, Češke, Njemačke, Urugvaja, Madagaskara i SAD-a, a točna varijacija boje kamena povezana je s njegovim podrijetlom. Ako volite raznolikost, svidjet će vam se boje i uzorci ovog jedinstvenog kolovoza!
Sa svojom poviješću ukorijenjenom u religiji i politici, ne čudi da je značenje Sardonyxa duhovno. Vjeruje se da nošenje ovog kamena u kolovozu daje duhovnu snagu i zaštitu od nesreće.
S vremenom je simbolika ovog kamena evoluirala da predstavlja hrabrost, stabilnost, sreću i zdravu komunikaciju.
Pokrili smo tri kolovoška rodna kamena, no možda se još uvijek pitate: zašto ih ima toliko?
Istina je da ova tri kamena rođenja nisu univerzalno priznata. Iako je Sardonyx najstariji od ova tri, često je izbačen s popisa u korist novijih dodataka, peridota i spinela.
Zapravo, do prije nekoliko godina, kolovoz je imao samo dva kamena rođenja. A prije toga, Sardonyx je bio primarni kamen rođenja za kolovoz.
Trenutno je službeni kolovozov rodni kamen peridot, a spinel i sardonyx su sekundarne opcije. Razlog zašto postoje tri je taj što postoji više karata rodnih kamena.
Moderna karta rodnog kamena prepoznaje peridot kao službeni kamen rođenja u kolovozu. Međutim, Sardonyx je primarni izbor u drevnoj karti. Najnoviji dodatak grafikonu je spinel, koji označava treći priznati dodatak modernom grafikonu. I tako je kolovoz dobio tri kamena!
Ovo je izvrsna vijest za kolovoške rođendane, jer mogućnosti su neograničene, pogotovo s obzirom na jedinstvene boje i uzorke koje ova tri dragulja nude.
