October Birthstone Necklaces

Our October birthstone collection features opal, tourmaline, and pink topaz, handcrafted in Colorado in 14K gold, gold-fill, and recycled sterling silver. Opal (Mohs 5.5 to 6.5) is the traditional October birthstone. Tourmaline (Mohs 7 to 7.5) is the modern birthstone, added in 1952. Pink topaz (Mohs 8) is a widely recognized October alternative. All three available from $20. Free shipping over $150.

Shop by stone: Opal Jewelry, Tourmaline Jewelry, or Pink Topaz Jewelry. For the full birthstone story, visit the October Birthstone Jewelry hub.
