This specimen is a transparent oval sky blue topaz weighing 1.14 carat, with dimensions of 7.94 by 6.07 by 3.42 millimeters. The carat weight sits just above the one carat threshold, a critical benchmark for collectors and designers, and delivers proportional face up spread and presence that reads as premium in both loose and set form. The measured depth of 3.42 millimeters gives an effective depth ratio of approximately 48.8 percent when compared to the mean of the length and width, a geometry that balances weight retention with optimal light performance. At 1.14 carat, this topaz benefits from a refined hand in cutting that preserves weight while producing a pleasing table and silhouette for use in a wide range of ring sizes and necklace settings, and the dimensions correspond well to standard mounting profiles without excessive bezel or gallery modification.
The gem displays a mixed brilliant cut, combining a brilliant styled crown with a faceted pavilion designed to enhance return of light. The cutter has employed a medium to slightly deep crown height paired with a pavilion facet scheme that compensates for topaz refractive indices, resulting in lively scintillation despite topaz having modest dispersion. Facet junctions are sharp and consistent, polish is graded excellent, and overall symmetry is controlled to industry tolerances, facilitating clean light echoes across the surface. Clarity is evaluated as eye clean at normal viewing distances, with no inclusions apparent to the unaided eye, which enhances apparent brightness and maintains color consistency across the table and facets. The girdle is even and suitable for conventional prong and bezel settings, and the culet is negligible, preserving uninterrupted light flow.
Color is described as sky blue with medium intensity, a balanced hue that reads lively under daylight and retains depth in indoor illumination. This color has been produced by controlled irradiation, a standard enhancement method for topaz, and the result is stable under normal wear conditions, though exposure to high temperatures should be avoided to preserve color integrity. The origin is Ceylon, Sri Lanka, a source with a documented history of fine quality gemstone material, and the stone exhibits the vitreous luster and refractive behavior typical of topaz. Given topaz hardness and directional cleavage characteristics, secure settings such as four or six prong mounts, low profile rub over bezels, or protective halo designs are recommended for everyday wear. This 1.14 carat oval sky blue topaz represents a premium choice for connoisseurs seeking a well cut, eye clean, transparently described gem, and it is offered by The Natural Gemstone Company with full disclosure of enhancement and origin, and with our recommendation for professional setting and care.
