Sensational 8.35ct blue black Indicolite Tourmaline

This large and rare example features an elegant resting black hue that reveals a gorgeous indicolite hue when held to the light. Its silky black body color looks opaque, but you can observe its palette shifting with movement, and in the sunlight it glows darkly. Measuring 17.9mm x 7.1mm x 5.6mm it has fantastic size with VS clarity, and every facet shimmers with its superior luster. Sourced from Nigeria. Untreated.
