0.76 Ct. Bi Color Sapphire from Ceylon (Sri Lanka)

This listing describes one transparent bi color sapphire weighing 0.76 carats, cut in an emerald shape with dimensions 5.20 x 4.43 x 2.94 mm. The stone originates from Ceylon Sri Lanka, and it has been heat treated to enhance tone and saturation. The cut is an emerald cut, characterized by linear step facets and a broad table that emphasizes the gem's color and clarity. Clarity has been graded as very very slightly included when evaluated at eye level, which means that the stone presents with only minute internal features that do not interfere with its overall transparency or visual appeal. The color intensity is described as intense, and the polish is excellent, producing crisp facet junctions and smooth facet planes. The Natural Sapphire Company presents this sapphire with full disclosure of its enhancement history and origin, reflecting the standard practices used to maximize the innate beauty of fine Ceylon stones.

The emerald cut lends a controlled, architectural aesthetic to this sapphire, emphasizing large, clean planes of color rather than a profusion of small scintillating flashes. The step facets create a hall of mirrors effect, producing broad flashes of light that move in ribbon like bands across the table and pavilion as the gem is tilted. Because the pavilion depth is modest relative to the table width, and because the polish is excellent, light return is steady and efficient, allowing the intense color to read consistently through the gem. The bi color character of this sapphire is expressed as distinct zones of hue within the body of the stone, which are artfully aligned with the step faceting so that the zones reveal themselves as you change the viewing angle. The very very slightly included clarity grading indicates that inclusions are minimal and fine in nature, often appearing as narrow silk or pinpoint features that do not distract from the gem at normal viewing distances, and the overall transparency remains high, which enhances both color and brilliance.

Under natural daylight this sapphire presents with a clear and vibrant expression of its intense blue, with secondary nuances becoming visible as the stone is moved. Open shade and indirect northern light will tend to display the lighter, more saturated side of the bi color range, resulting in a vivid cornflower to royal blue impression. In bright direct sunlight the larger facet planes create dramatic, linear highlights and deeper color saturation in the zones, producing pronounced contrast between the vivid bands and the darker areas, a quality that is particularly striking in emerald cut stones. Under cool white LED illumination the stone appears crisp and slightly more electric, the intense blue reading with high clarity, and the step facets deliver pronounced linear reflections that emphasize the gem moment by moment. Incandescent lighting imparts a warmer ambient effect, softening the highlights and gently deepening the blue toward a velvety tone, which enhances the stone when set for evening wear. Fluorescent light can cause the gem to appear slightly lighter in tone, allowing the bi color zoning to become more apparent across the step facets, while candlelight or other low warm light sources reduce contrast and emphasize depth of tone, creating a rich and intimate blue glow. In mixed lighting conditions the sapphire demonstrates dynamic personality, shifting harmoniously between lighter and deeper blue tones while maintaining overall intense color and excellent transparency.

From a practical perspective this 0.76 carat emerald cut bi color sapphire offers versatility in design and enduring wearability. The emerald cut is well suited to settings that showcase the stone as a solitary focal point, such as a classic solitare or a three stone composition, and the clean geometry pairs exceptionally well with tapered baguette or channel set diamond accents. Given its Ceylon origin and intense color, the sapphire carries the classic appeal associated with Sri Lankan material, which is prized for its clarity and bright tonal range. The heat treatment applied is a standard and stable enhancement that improves color uniformity and saturation, and when disclosed it does not diminish the gem's durability for everyday wear. Care recommendations include avoiding prolonged exposure to harsh chemicals, and arranging periodic professional cleaning and inspection when mounted, to preserve the stone and the setting. The Natural Sapphire Company stands behind transparent disclosure of origin and enhancement, and this gem is presented with those details to help you make an informed selection.
