1.50 Carat Natural Loose Ink Blue Color Tourmaline Cushion Cut Afghan Gemstone

Mined from the famous pegmatite fields of the Panjshir Valley, Afghanistan, this 1.50 Carat Natural Loose Ink Blue Tourmaline displays a deep, mysterious navy-to-midnight blue hue with electric indigo secondary flashes when light strikes its facets. Precision-crafted into a classic cushion cut, its soft, rounded perimeter and custom-tailored pavilion faceting work together to open up the gem's intense color depth, generating lively, edge-to-edge scintillation across its crown. The gemstone boasts superior eye-clean clarity and exceptional crystal transparency, allowing light to traverse fluidly through its crystalline body without dark extinction zones or cloudiness. Completely natural, unheated, and untreated, this pristine 1.50-carat Afghan tourmaline offers a rare indigo palette paired with highly versatile, ring-ready proportions, making it a sophisticated centerpiece for a bespoke signet ring, an elegant solitaire pendant, or an elite fine gemstone portfolio.
