12.88 Ct. Yellowish Orange Citrine from Brazil

This transparent 12.88 carat citrine from Brazil is presented in a precise princess shape with dimensions of 13.14 x 12.13 x 10.91 mm, princess cut, vivid color intensity, and an excellent polish. The gemstone is yellowish orange in tone with a clarity grade described as very very slightly included evaluated at eye level, indicating apparent eye cleanliness with minor internal features that do not detract from overall visual performance. The stone has been heat treated, a common and stable enhancement for citrine, applied to optimize the warm color saturation without affecting durability. The Natural Gemstone Company confirms these characteristics and the workmanship, with facet junctions and pavilion geometry executed to produce balanced light return and consistent proportions for a dignified table presence.

Under varying lighting conditions this citrine exhibits predictable and attractive behavior. In bright natural daylight the stone reads as a clear, luminous yellowish orange, with the vivid saturation remaining well defined, while the princess cut facets create crisp, angular reflections and steady brilliance across the table and crown facets. In direct sunlight the stone shows stronger contrast between facet planes, yielding lively scintillation when the gem or the viewer moves, though dispersion or fire is modest given quartz refractive properties, so the visual impact is mainly color and facet contrast rather than spectral flashes. Under warm incandescent or halogen illumination the citrine deepens to richer orange and honey tones, appearing warmer and more saturated, and the excellent polish enhances subtle internal glow. Cool white LED or fluorescent lighting tends to emphasize clarity and facet definition, producing sharp mirror like reflections and a slightly lighter appearance in the yellow component of the color. In low light or candlelight the gem reveals its warmth as a soft, luminous glow, with the cut concentrating light toward the table and producing elegant, restrained scintillation. When set in typical prong or open gallery settings the stone maintains strong light transmission and visual depth, and the combination of vivid color, skilled princess cutting, and high polish ensures reliable performance across common wearing environments.
