Niccolite Value, Price, and Jewelry Information

Niccolite is always cut as cabochons. The color is a delicate peachy red and is extremely beautiful, especially in polished material. The metallic luster combined with this unusual color is very distinctive. Niccolite is hard enough to be worn on bola ties and pendants. It sometimes tarnishes to a darker color, but a coat of clear nail polish may prevent this.
