Tourmaline
Tourmaline
Tourmaline is the gemstone with the widest natural color range of any in fine jewelry. Hot pink to watermelon to forest green to near-black blue, all naturally occurring within the same mineral family, each one a completely different character. October's alternate birthstone, and one of our favorites to select precisely because the stone itself makes each tourmaline jewelry piece unlike the last. Stones chosen for color strength and natural saturation, set in designs where the gem is clearly the point.
