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

This sapphire offered by The Natural Sapphire Company is a transparent bi color sapphire weighing 3.05 carat, with precise dimensions of 9.33 x 7.21 x 4.37 mm. The stone is cut in a classic emerald cut, a step cut that emphasizes broad, parallel facet planes and a capacious table to reveal internal color subtleties. The color intensity is classified as intense, producing a striking face up presence that transitions across blue and green tones that read distinctly depending on orientation and light. Clarity has been evaluated at eye level as very very slightly included, which renders the gem effectively eye clean for most practical wear while preserving natural internal character under magnification. This sapphire originates from Ceylon Sri Lanka, a source known for producing transparent crystals with lively color, and it has received a standard heat treatment enhancement to optimize hue and clarity while maintaining the stone integrity.

The cutting and facet architecture of this piece were executed with deliberate technical intent to maximize both color presentation and light performance. The emerald cut exhibits long step facets on the crown and pavilion that create a hall of mirrors effect, favoring broad flash reflections and controlled light return rather than dispersed scintillation. The length to width ratio of 1.29 yields a balanced rectangular outline that reads as elegant but substantial in hand, and the pavilion depth of 4.37 mm has been calculated to preserve face up color without introducing a washed out window in the large table area. The cutter oriented the crystal to align pleochroic axes with the table to emphasize the bi color transition, and the excellent polish ensures crisp facet junctions and minimal surface abrasion so that facet planes act as precise mirrors. Symmetry across pavilion facets is tightly controlled to avoid offset flashes that can disturb the linear step pattern, which is essential in an emerald cut where proportional harmony defines the visual rhythm of reflections.

Color behavior in this bi color sapphire is a defining attribute, and the stone demonstrates a deliberate distribution of green and blue that can be described as an intense green to blue transition. Viewed table up under mixed incandescent and daylight balanced light, areas nearer the pavilion and crown junction reveal deeper blue notes, while plate regions and corners can display a vibrant green depending on viewing angle. This pleochroic response is typical of corundum with combined chromium and iron titanium chromophores, and the cutter exploited that property to produce a stone that changes character with movement. Heat treatment was applied to enhance saturation and to reduce the visibility of minor silk and internal zoning, a treatment method that is stable and widely accepted in the trade when performed within established parameters. The end result is a gem that reads vivid and complex across light sources, offering collectors and connoisseurs a dynamic color experience rather than a uniform flat tone.

From a clarity and setting perspective this sapphire balances commercial wearability with collector grade attributes. The very very slightly included grade evaluated at eye level indicates that inclusions are minimal and do not interrupt the gem transparency in normal viewing, and under loupe or microscope these inclusions present as minute feathers or silk that attest to the natural origin without compromising durability. The emerald cut has slightly vulnerable corners that benefit from protective prong design or a bezel element when set for everyday wear, and the substantial table and pavilion geometry make this stone an ideal centerpiece for a solitaire ring, a custom tailored halo mount, or a distinctive pendant that showcases the bi color transition. The excellent polish and precise facet control also make the gem highly suitable for collectors who appreciate stones that respond predictably to light and display technical cutting excellence.
