Bicolor Blue-Green Tourmaline Crystals on Matrix – Afghanistan

Directly from the renowned mining districts of Afghanistan, this 12.75ct specimen showcases the elite "bicolor" effect that collectors highly prize. The primary Tourmaline crystal displays a sophisticated gradient, shifting from a rich, saturated Blue (Indicolite) at the base to a crisp, vibrant Green toward the termination.

The crystals are aesthetically hosted on their original matrix, providing a natural contrast that highlights the gems' transparency and vitreous luster. This is a 100% natural, untreated specimen, offering sharp terminations and excellent light transmission. Its compact size makes it an ideal addition to a high-end thumbnail collection or a specialized tourmaline display.
