Did you know August actually has three birthstones? Get ready to learn about all three of these beautiful and remarkable birthstones!\n
Sardonyx was the original unofficial birthstone for August for centuries. When the National Association of Jewelers began promoting birthstones in 1912, peridot was added as August’s second birthstone.\n
Spinel was added as a third in 2016 in an effort to modernize the birthstone list. Here are 24 things we bet you didn\u2019t know about the three birthstones of August.\n
Peridot is a silicate mineral, meaning it is made up of silicon and oxygen. It is a variety of the common silicate, olivine.\n
While olivine is a plentiful material, gem-quality peridot is, in fact, quite rare. This rarity is caused by peridot\u2019s unstable structure on Earth\u2019s surface.\n
Peridot is one of the few gemstones only come in one color, in this case, a shade of olive green. The intensity of this green depends on how much iron is in the gemstone\u2019s crystal structure.\n While gems commonly form in the Earth\u2019s crust, peridot is one of only two gems that do so in the molten rock of Earth\u2019s upper mantle.\n Peridot can even be found in meteorites! This peridot from outer space differs from the kind found on Earth as it contains no nickel.\n Peridot can also be found in lava flows. But, while these can be a particularly rich source of olivine, actual gem-quality peridot from these sources is scarce.\n One of NASA\u2019s telescopes identified olivine\/peridot in the gassy cloud of a forming star, with crystallized particles swirling in the currents like green rain.\n The vast majority of the world’s peridot supply comes from Arizona‘s San Carlos Apache Reservation.\n The world\u2019s largest cut and polished peridot is 310 carats and is on display in the Smithsonian. For perspective, an average diamond engagement ring is only one or two carats in size.\n Sardonyx has a reddish appearance with white stripes. This pattern is formed due to alternating layers of sard and onyx, which are both types of the mineral chalcedony.\n Onyx is chalcedony that\u2019s striped white, grey, and black. Onyx got its name from the Latin word for \u201cfingernail\u201d or \u201cclaw\u201d because the white bands are the same color as nails.\n Sard is another type of chalcedony. It\u2019s primarily red, orange, or brown because it contains iron oxide. The mineral sard takes its name from an ancient city called Sardis, located in what is now Turkey, as the mineral was common there.\n Sardonyx has been popular for thousands of years, all the way back to Ancient Egypt. It has been used to create bas-relief cameos in stone, commonly depicting the faces of gods, kings, heroes, and beauties. These works of art are called intaglios, from the Italian word meaning \u201cto engrave.\u201d\n Ancient Roman rulers used signet rings and seals made of sardonyx to imprint wax insignia on important documents because melted wax doesn\u2019t stick to it.\n While sardonyx is found around the world, some of the finest examples come from India. The sharp, defined edges between the layers of sard and onyx are what make these specimens particularly noteworthy.\n Spinel (spin-ELLE) comes from the Latin word \u201cspinella,\u201d meaning \u201cthorn,\u201d because its pointed shape imitates the shape of a thorn. Spinel usually takes the form of an octahedron, with two 4-sided pyramids stuck together at the base.\n This beautiful gemstone is made of magnesium, aluminum, and oxygen and has an isometric crystal structure.\n Pure spinel is as clear as glass. Various mineral impurities imbue it not just with every color of the rainbow but with grays and black too!\n Spinel is found in the same places where sapphires and rubies are mined, leading to confusion because they look nearly identical. For centuries, any red-colored gem was called a ruby, and any blue-colored gem was a sapphire.\n In 1783, French mineralogist Jean-Baptiste Louis Rom\u00e9 de l\u2019Isle developed methods of distinguishing identical-looking minerals by testing their mineral makeup. This was the first revelation that many \u201crubies\u201d were actually spinel.\n The most famous spinel is called \u201cThe Black Prince\u2019s Ruby.\u201d It was set in the British Imperial State Crown above the Cullinan II diamond. Only later was it found that the 170-carat stone is spinel and not ruby.\n Although red-colored spinel is rarer than ruby and is often much larger than typical rubies, it\u2019s still usually available at one-tenth of the price of a genuine ruby.\n Synthetic spinel also has industrial uses. It provides heat-resistant coatings on things such as metal tools. It\u2019s also added to bricks and ceramics.\n Because synthetic spinel is available in almost every color, it can be used to imitate nearly every other gemstone.\n And there you have it! People born in August are fortunate enough to have three such divergent gems to pick from to reflect their personality and pocketbook.\n Each unique mineral tells a different story. Kings and queens, leaders and laypeople, jewelers and geologists have all brought us this magnificent selection of birthstones to celebrate the month of August.\n","protected":false},"excerpt":{"rendered":" Did you know August actually has three birthstones?
