1.53 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent yellow sapphire weighs 1.53 carat, and has an asscher cut in an octagon shape, with precise dimensions of 6.69 by 6.61 by 3.65 mm, clarity evaluated as eye clean at normal viewing distance, and a medium color intensity that reads as a pure, warm yellow. The facet arrangement follows the classic asscher geometry, producing a stepped pavilion and an elevated crown that emphasize clarity and internal light movement. The finish is described as excellent polish, and the stone is natural with no enhancement, originating from Ceylon, Sri Lanka. These objective specifications define a gem that combines measured proportions with a refined optical presence, suitable for settings that prioritize both symmetry and the transparent transmission of color.

The asscher cut offers a disciplined geometry that complements the gemological attributes of this sapphire, producing a balance between scintillation and broad flashes of light rather than extreme brilliance. The octagonal outline and the square pavilion facets create concentric reflections that highlight the stone center and maintain a consistent color face up. With the given table and depth dimensions related to the provided measurements, the pavilion depth and crown angle are calibrated to present the medium yellow evenly across the table without creating dark zones or excessive windowing. The eye clean clarity allows the cut to operate with minimal internal interruption, and the excellent polish supports crisp facet junctions and well defined facet planes, ensuring the stone performs as intended in both direct and diffused light.

The heritage of Ceylon sapphires is long and well documented, and yellow sapphires hold a particular place in traditional jewelry and cultural practice. In South Asian gem traditions, yellow sapphire has been valued for centuries in signet rings, talismans, and ceremonial ornaments, often associated with prosperity, learning, and official status. The gemological properties of Ceylon stones, including their clarity and color range, have made them desirable for such uses, and asscher cuts and other step cuts have historically been chosen to complement a gem that benefits from a clear, even color distribution. This sapphire aligns with that lineage, being an untreated Ceylon stone that exhibits the transparent, medium yellow tone preferred in classical pieces, and it is therefore well suited to designs that reference or reinterpret traditional forms.

The Natural Sapphire Company presents this gem as an example of measured quality and cultural continuity, an untreated Ceylon sapphire that retains the material integrity valued by collectors and craftsmen. Its weight and dimensions make it appropriate for a central gem in bespoke engagement rings, dress rings, and important heirloom pieces, and setting choices such as stepped bezels, four or six prong settings, or a protective halo will preserve the optical balance while reflecting the asscher geometry. For design planning, the near square table and clean clarity permit both closed and open settings, and the absence of enhancement confirms the stone will age and respond to care in line with natural sapphires from the region. This description provides the technical and contextual information needed to assess how the gem will function aesthetically and historically within a considered jewelry design.
