9.70 Ct. Sky Blue Topaz from Brazil

One remarkable treasure awaits the collector who seeks singular beauty, a transparent sky blue topaz weighing 9.70 carats, crafted into an elegant oval shape that measures 15.03 by 12.91 by 7.10 millimeters. This gem exhibits a mixed brilliant cut that marries the best attributes of brilliant faceting with precise crown angles, delivering a balance of depth and surface flash that is rare at this scale. The color presents with medium intensity, a pure and airy blue that evokes high sky light, and the polish is excellent, giving every facet a mirror finish. Clarity has been graded as very very slightly included at eye level, meaning that the stone reads as visibly clean to most observers, while maintaining the natural characteristics that confirm its authenticity. The topaz has been enhanced by irradiation to realize its vivid sky blue hue, and its origin in Brazil speaks to a lineage of well known topaz sources and expert lapidary traditions.

The geometric faceting of this oval topaz is the centerpiece of its performance, conceived to allow maximum play of light through each precisely cut plane. The mixed brilliant layout distributes small, dynamic facets across the crown and pavilion, creating an intricate network of light pathways that return scintillation and subtle flashes of brilliance to the viewer. Because topaz has a moderate refractive index and modest dispersion, the cutter has optimized facet size and angles to enhance brightness rather than relying on spectral fire alone, the result being a lively, lively gem that sparkles with an even, ocean like shimmer. As the stone rotates, light fractures across its geometry, alternating between broad flashes and pin point scintillation, a visual rhythm that reads as both refined and energetic. The symmetry and alignment of facets ensure that light enters and leaves the gem with minimal leakage, maximizing perceived size and presence on the hand or in a bespoke setting.
