October birthstone pendants feature two distinct gems: opal and pink tourmaline. Opal displays a play-of-color effect caused by silica spheres diffracting light, while tourmaline offers consistent pink to red hues from manganese content. Our collection holds 28,529 pendants in .925 sterling silver, priced from $16 to $11,402. Each pendant showcases natural stones sourced from Australia, Ethiopia, Brazil, and Madagascar.
