10.12 Ct. Orangish Brown Tourmaline from Ceylon (Sri Lanka)

This transparent 10.12 carat cushion shape orangish brown tourmaline presents precise dimensions of 15.37 x 11.55 x 8.27 mm, a mixed brilliant cut, a clarity grade of very very slightly included when evaluated at eye level, intense color intensity, and an excellent polish, untreated and originating from Ceylon Sri Lanka. The mixed brilliant faceting integrates a brilliant style crown with a more structured pavilion, balancing scintillation and color saturation by directing return light through broad, evenly proportioned facets. The cushion outline with slightly rounded corners and the substantial 8.27 mm depth create a strong face up presence, the 15.37 x 11.55 mm table providing an expansive window for the stone color to read consistently across the table without appearing patchy. The excellent polish enhances facet junction crispness and minimizes surface diffusion, ensuring maximum contrast between light and dark facet planes, and the very very slightly included clarity at eye level confirms minimal internal disruptions to brilliance or light passage.

Color is the primary attribute that sets this tourmaline apart, the orangish brown hue showing an intense saturation that performs dramatically under varied lighting, leaning warmer and more amber in incandescent light, and revealing complex brown and copper inflections in daylight. The mixed brilliant cut functions to both emphasize fire from the crown and to retain depth of color from the pavilion, permitting the stone to show lively flashes while preserving the core orangish brown tone, a quality prized by connoisseurs who require both spectacle and rich chroma. Because the stone is not enhanced, the intense color is entirely natural, and the origin of Ceylon Sri Lanka contributes to provenance value among collectors, reflecting a known source with a history of fine tourmaline occurrences. The dimensions and weight make this gem suitable for a variety of settings, and the facet architecture supports open back or partial gallery mounts to optimize light admission, or a well executed bezel to intensify hue when set against warm metals.

For jewelry design applications, the proportions and cut of this tourmaline will stand out as a central stone in a solitaire ring, a substantial pendant, or a custom three stone composition where side stones can be calibrated to contrast or complement the orangish brown bodycolor. The strong polish and precise facet symmetry simplify lapidary matching and mounting, and minimal inclusions allow secure prong settings without visible interruptions to the visual field. The Natural Gemstone Company presents this tourmaline as an untreated demonstration of skilled cutting and natural color potential, an ideal choice for clients seeking a bold, technically refined centerpiece that will command attention in any jewelry setting.
