October Birthstone Earrings in Sterling Silver  

Real Opal and Pink Tourmaline Set in .925 Silver

Opal rates 5.5 to 6.5 on the Mohs hardness scale, making it softer than many gemstones and best suited for earrings rather than rings. Most opals form in sedimentary rock when silica-rich water seeps into crevices and deposits microscopic spheres over millions of years. Australian mines produce the majority of gem-quality opal, though Ethiopian and Mexican sources contribute notable specimens. The play-of-color depends on sphere size and arrangement within each stone. Pink tourmaline measures 7 to 7.5 on the Mohs scale, offering greater durability for daily wear. This boron silicate mineral gets its color from manganese content. Brazilian and Afghan deposits yield most pink tourmaline used in jewelry. Both October birthstones carry meanings of hope and emotional balance in traditional gem lore. SilverRush Style has supplied natural stone jewelry since 2005. Each pair of earrings ships free within the US, set in solid .925 sterling silver with genuine opal or tourmaline. Browse the full collection to find your size and stone preference.
