38.91 Ct. Multi Color Sapphire Crystal from Ceylon (Sri Lanka)

This translucent multi color sapphire from Ceylon, presented by The Natural Sapphire Company, weighs 38.91 carats, and measures 20.66 x 8.12 x 7.89 millimeters. The gem exhibits a various shape rough crystal cut, a form that preserves natural crystal terminations and axial elongation, and this geometry yields a length to width ratio of approximately 2.55 to 1, making the stone ideal for linear and axial settings. Clarity is graded as very slightly included when evaluated at eye level, inclusions that are characteristic of natural material and that contribute to the stone s internal texture without interrupting translucency. Color intensity is medium, with discrete multi color zoning across the body of the crystal, a distribution that responds strongly to orientation and lighting due to the inherent pleochroic behavior of corundum. The surfaces have been finished to an excellent polish despite the rough crystal cutting approach, which results in a tactile surface and soft reflective planes rather than the highly faceted brilliance of traditional cuts. No enhancement has been applied, so the sapphire presents its native color balance and internal features unaltered, and its origin from Sri Lanka is retained in the overall tone and crystal habit.

From a customization and setting perspective, the stone s elongate, bi point like profile and stable depth offer numerous design pathways. When left in its rough crystal cut state, the gem lends itself to organic and contemporary settings such as custom bezel rails, tapered bar mounts, or low profile half bezels that protect the natural terminations while exposing color zones along the pavilion and crown. For a more architectural approach, an east west orientation in a bar or saddle mounting will emphasize color banding along the length, while vertical settings in pendant or drop earrings will accentuate point to point reflections. The stone is also well suited to two stone and three stone arrangements, where the facets and zones can be paired with calibrated accent diamonds or colored gemstones to frame preferred hues. For clients who prefer classical symmetry, The Natural Sapphire Company can coordinate precision re faceting to a defined outline such as an elongated oval or marquise, or to mixed brilliant and step combinations, preserving maximum weight while improving optical symmetry, or perform targeted polishing to enhance a particular color region, all executed by experienced lapidaries who account for the sapphire s crystal axes and inclusion pattern.

Practical recommendations for production and long term performance focus on protection and visual optimization, and these are best implemented in consultation with The Natural Sapphire Company s design team. Bezel settings with a modest lip are recommended for rings where daily wear is anticipated, because the bezel protects natural terminations and reduces the risk of impact on narrow points, and a semi open gallery can be engineered to permit back illumination and color play. When using prongs, a four or six prong configuration with reinforced shoulders will secure the elongated profile without obscuring the principal color zones, and custom saddle designs can integrate tension and pressure distribution to avoid stress concentrations on the crystal terminations. Metal choice will influence perceived color, with yellow and rose alloys warming the honey and yellow zones, and white alloys or platinum emphasizing cooler blue and gray tones. For bespoke commissions we provide CAD renderings and prototype wax models to evaluate how the stone s medium color intensity and translucent body interact with metal and accent stones, and we can advise on gemological orientation to exploit pleochroism, on girdle handling and seat depth to minimize removal of weight, and on polishing strategies to preserve natural character while enhancing wearability.
