October Birthstone Pendants in Sterling Silver  

Natural Opal and Pink Tourmaline Pendant Collection

Opal forms over millions of years as silica-rich water seeps into rock crevices and deposits microscopic spheres. These spheres create the signature color flash that shifts with viewing angle. Australian opals tend toward white body tones with blue-green fire, while Ethiopian specimens often show orange and red flashes against darker backgrounds. Opal rates 5.5 to 6.5 on the Mohs hardness scale, making pendants an ideal wear choice since they avoid the direct contact rings receive. Pink tourmaline, the alternate October birthstone, scores 7 to 7.5 on the Mohs scale and resists scratching better than opal. Most pink tourmaline in our pendants comes from Brazilian mines, where the gem forms in pegmatite rock. The color ranges from pale rose to deep magenta depending on manganese concentration. Both stones set in .925 sterling silver provide durability for regular wear. SilverRush Style has offered natural stone jewelry since 2005.
