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

This offering from The Natural Sapphire Company is a transparent, cushion shape bi color sapphire weighing 2.18 carats, with precise dimensions of 8.51 x 6.60 x 4.30 mm. The stone is fashioned in a mixed brilliant cut, engineered to balance scintillation and light return across the pavilion and crown. Clarity is graded as very slightly included when evaluated at eye level, a condition that preserves exceptional transparency while imparting subtle character under close inspection. Color behavior is described as medium intensity, with distinct zones of blue and a lighter, near neutral tone that coexist within the crystal lattice. Polish quality is excellent, contributing to crisp facet junctions and minimal surface disruption, and the sapphire is unenhanced, retaining its natural state as mined in Ceylon, Sri Lanka. These measured attributes combine to provide a gem that is stable in appearance, straightforward to set, and predictable in performance under varied lighting conditions.

Optical performance emphasizes the interaction between the bi color zoning and the mixed brilliant faceting, resulting in dynamic color shifts as the stone moves. The deeper blue areas deliver saturated flashes and depth through the pavilion, while the lighter side enhances perceived transparency and brightness at the crown. The mixed brilliant cut maintains well defined facet planes that channel light to and from the eye, producing balanced brilliance and controlled dispersion without excessive fire. The very slightly included clarity grade is consistent with natural origin, and inclusions are minute at practical viewing distances, presenting no impairment to the gem’s visual impact. Given its dimensions and cut proportions, this sapphire is suitable for a range of mounting styles, including solitaires, halo designs, and mixed metal settings, and its stable, untreated nature supports long term wear with proper care.

The provenance from Ceylon informs both scientific and aesthetic valuation. Sri Lankan sapphires are historically prized for their varietal colors and clean crystal habit, and this specimen exemplifies those regional characteristics through its medium color intensity and transparent body. Unenhanced status is an important consideration for connoisseurs and for those seeking gems with minimal human alteration, and it simplifies appraisal and future resale considerations. The cushion outline and measured depth of 4.30 mm give the stone a classic silhouette that sits comfortably within contemporary design languages, while the mixed brilliant cut modernizes the table view and creates a lively presentation on the finger or pendant. For practical considerations, the gem responds well to standard jeweler mounting techniques, and its clarity and polish facilitate stone setting without the need for extensive modification.

A romantic narrative is suggested by the stones dual tones, evoking the meeting of evening and dawn over the Indian Ocean, a moment when cobalt sky yields to pale light, and two distinct chromas gently embrace. In this reading, the richer blue represents fidelity and depth, while the lighter hue suggests clarity and enduring openness, together forming a visual metaphor for a balanced partnership. The very slightly included clarity becomes part of that story, a reminder that authenticity includes minor imperfections that catch the eye and mark the gem as genuine. Presented by The Natural Sapphire Company, this 2.18 carat Ceylon bi color sapphire offers both a technical profile that will satisfy exacting specifications, and a quiet, evocative narrative that can be woven into a bespoke commission or an heirloom design.
