Frequently asked questions

  • What are October's birthstones?

    October has two official birthstones: opal (traditional) and tourmaline (modern, added 1952). Opal is known for play-of-color. Pink tourmaline offers vibrant color and more durability.

  • Which October birthstone is more durable?

    Tourmaline (Mohs 7 to 7.5) is harder and better for everyday rings and bracelets. Opal (Mohs 5.5 to 6.5) is softer and best in protective settings.

  • What does tourmaline symbolize?

    Tourmaline symbolizes love, compassion, emotional healing, and creativity. Pink tourmaline is connected to the Heart Chakra. It is associated with Libra and Scorpio.

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.
