1.36 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This transparent yellow sapphire presents a precise combination of weight, proportions, and origin. The gem weighs 1.36 carats, and measures 7.80 x 4.84 x 3.41 mm. It has an emerald cut, and it is from Ceylon Sri Lanka. The clarity grade is eye clean, evaluated at eye level, and the polish is excellent. There has been no enhancement, and the color is described with an intense color intensity. The Natural Sapphire Company is the source of this stone, and this description reflects its natural characteristics as observed in loupe and hand held light conditions.

The geometric faceting of the emerald cut has been executed to maximize controlled light play across the pavilion and crown. The rectangular table and long step facets on the crown and pavilion create broad, parallel planes that return light in even ribbons rather than in a scattered brilliant pattern. This configuration yields an effect often called elegant flash, where the interplay between light and shadow forms linear reflections that emphasize clarity and color. The shallow to medium depth of the stone at 3.41 mm supports effective transmission and return of light, and the stepped faceting along the pavilion produces repeated internal reflections that enhance perceived size and depth without sacrificing transparency. Symmetry of facet junctions and the excellent polish contribute to crisp facet boundaries, which is essential for the hall of mirrors effect typical of a well cut emerald shape. The result is measured, directional brilliance that responds to movement with alternating bands of light and soft, reflective planes.

Color distribution and clarity work in concert with the faceting to define the visual character of this sapphire. The intense color intensity transmits a lively golden yellow that remains evenly distributed across the table and through the girdle. Because the stone is eye clean at typical viewing distances, the absence of visible inclusions allows the step facets to operate unimpeded, producing a clean, uniform wash of color punctuated by brighter flashes along facet edges. The lack of enhancement means that the color and optical behavior are inherent to the crystal, and the Ceylon origin is consistent with a natural palette of bright, lively yellow tones. Under mixed lighting the stone will present both softer, warm yellow faces and more saturated flashes as light is captured and returned by the long facet planes. The effect is particularly suited to settings that allow light to enter the pavilion and reflect through the table, preserving the gem kinetic quality.

From a practical gemological and design perspective this sapphire is well suited to a range of custom and classic settings. At 7.80 x 4.84 mm and 1.36 carats it functions comfortably as a dominant center stone in a refined solitaire, or as the central element within a delicately proportioned halo. The emerald cut lines lend themselves to minimalistic mounts that emphasize linearity and clarity, as well as to bezel or prong settings that protect the corners while preserving the stone geometry. Care advice follows standard recommendations for natural, untreated corundum, including routine cleaning with warm water and mild detergent, gentle brushing with a soft brush, and avoiding harsh chemicals and abrasive cleaners. Professional inspection of the setting is advised periodically to ensure secure prongs and to preserve the precise alignment that allows maximum light play. This yellow emerald cut sapphire from The Natural Sapphire Company combines natural provenance, measured proportions, and considered faceting to deliver a gem that displays consistent color, exceptional clarity to the eye, and a disciplined light performance suitable for enduring jewelry designs.
