2.84 Ct. Rubellite Tourmaline from Madagascar

This listing describes a single transparent rubellite tourmaline from Madagascar, weighing 2.84 carats, cut into an oval measuring 10.82 by 7.91 by 5.52 millimeters. The gem is fashioned with a mixed brilliant cut to balance face-up color and internal light return, and it is evaluated as very slightly included at eye level, indicating minimal visible inclusions to the unaided eye. Color is classified as vivid, exhibiting a saturated reddish-pink tone, and the stone presents an excellent polish that enhances facet definition and surface luster. The material has undergone standard heat treatment to improve color uniformity and stability. The Natural Gemstone Company supplies this specimen with its origin from Madagascar and with full disclosure of enhancement and clarity characteristics.

When comparing the optical performance of this rubellite to more common gemstones, its distinctive quality is color-driven brilliance rather than the high dispersion or fire associated with diamonds. Tourmaline typically has a lower refractive index than corundum and diamond, so it will not exhibit the same degree of scintillation or spectral fire, however the intense, saturated reddish-pink hue of this rubellite produces a strong face-up brightness and visual depth that makes the stone read larger and more vivid in jewelry. Compared with ruby and pink sapphire, which owe much of their appeal to strong saturation combined with corundum’s higher refractive index, this rubellite stands out through its combination of vivid hue and the mixed brilliant facet arrangement, which maximizes contrast and scintillation specific to tourmaline’s optical properties. Additionally, rubellite frequently displays pleochroism, and this specimen shows dynamic shifts in tone and intensity when viewed from different angles, an effect that contributes to a lively, three-dimensional appearance distinct from the more uniform color of many corundum pieces.

Given a hardness in the mid-range for gem materials and the excellent polish and clarity of this example, it is well suited for rings and pendants when set protectively. The disclosed heat treatment is a commonly accepted enhancement for tourmaline and does not detract from the stone’s visual appeal. The Natural Gemstone Company can provide further measurement verification and photographic documentation on request, and can advise on setting options that preserve the stone’s color and integrity.
