4.63 Ct. Green Sapphire from Ceylon (Sri Lanka)

One transparent, heart shape, green sapphire, weighing 4.63 carats, is presented from The Natural Sapphire Company, with dimensions 9.39 by 10.27 by 6.55 mm. The stone is faceted with a mixed brilliant cut, and it exhibits a light color intensity, a clarity grade of slightly included, evaluated at eye level, and an excellent polish. The sapphire is from Ceylon, Sri Lanka, and it has received no enhancement. These objective specifications define the material parameters and set expectations for its visual performance and suitability for fine jewelry, whether set as a solitaire or incorporated into a more complex mounting.

The mixed brilliant cut applied to this heart shaped sapphire is specifically designed to balance brilliance and depth of color, and to maximize return of light to the viewer. By combining a brilliant style crown with a complementary pavilion arrangement, the cutter achieves tightly controlled facet geometry that distributes light across the table and crown facets, producing concentrated flashes of white light known as brilliance, together with smaller, lively scintillation as the stone moves. The crown facets capture incident light and refract it into the body of the gem, while the pavilion facets reflect that light back through the crown with minimal leakage. In this sapphire, careful facet alignment and precise facet junctions ensure that light paths are coherent, converting internal reflection into visible brightness, rather than allowing energy to escape through poorly cut angles. The result is a performance that enhances the apparent brightness of the gem, while the mixed cut maintains enough facet planes to give a depth of character to the green hue without overwhelming it.

The heart shape itself imposes specific cutting challenges and opportunities that influence light behavior. The subtle lobes and central cleft require exact symmetry to prevent uneven light distribution, and the rounded outline must be matched to a pavilion design that supports consistent return. In this instance, the cutter has maintained proportional lobes, a well-defined cleft, and consistent girdle thickness, producing a balanced face up appearance where light is evenly reflected across the table and around the lobes. The slightly included clarity grade, evaluated at eye level, means that inclusions are present but do not dominate the stone when viewed normally, and because the sapphire is transparent they are often assimilated into the overall light pattern rather than interrupting it. Excellent polish further contributes to optical performance by minimizing surface diffusion and feathering, allowing crisp facet reflections and strong contrast between bright and dark areas. The light color intensity of the green tone works in tandem with the cut to preserve tone saturation while allowing significant light return, so the gem reads as lively and luminous rather than dull or overly dark.

In practical settings, the cut characteristics of this sapphire make it versatile and well suited for designs that emphasize the stone as the focal element. Open prong or low bezel settings that allow light to enter from the pavilion will complement the mixed brilliant geometry and maximize brilliance, while secure three prong or halo designs can provide additional visual impact without obstructing critical facet angles. The dimensions 9.39 by 10.27 by 6.55 mm give the gem a comfortable presence on the finger, and the heart shape communicates both classic and contemporary sensibilities. Because the sapphire is unenhanced and originates from Ceylon, Sri Lanka, it carries the natural attributes prized by collectors and connoisseurs, and its cutting quality demonstrates the attention to proportion and finish that defines The Natural Sapphire Company approach. For those seeking a heart shaped green sapphire where the cut has been executed to enhance light reflection and visual appeal, this specimen represents a carefully considered balance of optical performance, natural character, and workmanship.
