2.14 Ct. Bi Color / Parti Sapphire from Ceylon (Sri Lanka)

This 2.14 carat transparent bi color parti sapphire from Ceylon, presented by The Natural Sapphire Company, is an exemplar of precise cutting and natural color interplay that makes it an exceptional choice for an engagement center stone. The stone measures 7.20 x 5.90 x 5.07 mm, and its emerald cut faceting imparts a disciplined geometry that showcases the sapphire s internal structure. Clarity is graded very slightly included evaluated at eye level, ensuring that the step facets reveal broad planes with minimal distraction. Color intensity is light, and the parti character yields distinct zones of hue that read as pastel blue and soft yellow green depending on viewing angle and light source. No enhancement has been applied, confirming the sapphire s natural state and preserving its inherent material qualities.

Technically, the emerald cut used here is a classic step cut, with a rectangular table and successive rows of parallel facets on the crown and pavilion. The crown facets form long rectangular steps that lead the eye toward a wide table, while the pavilion consists of complimentary step facets that create the hall of mirrors effect typical of well executed emerald cuts. The cutter has achieved excellent polish, which is evident at facet junctions and along facet planes, producing crisp, reflective surfaces and minimal surface abrasion. Symmetry is precise, the bezel facets align with the pavilion steps, and the table facet is centered, producing balanced light return. Because the cut emphasizes clarity and the broad flashes of reflected color rather than scintillation, it is especially effective for a parti sapphire where broad color fields are desirable.

Proportions are an important consideration for a wearer who values both aesthetics and performance, and this sapphire s proportions are notably deep with a depth ratio of approximately 77.4 percent based on the average of the length and width. The relatively deep pavilion concentrates light into the parallel facet structure, enhancing the contrast between the color zones and imparting depth to the stone rather than maximizing surface spread. For an engagement setting this means a statement of refined presence rather than a mirror of dispersed brilliance. The very slightly included clarity grade indicates that inclusions are minor and do not impact the stone s face up presence at typical viewing distances, while also offering a degree of natural fingerprint that confirms its untreated origin. The absence of heat or other enhancement preserves the original crystal lattice and color distribution, attributes that discerning clients often prioritize for provenance and rarity.

From a practical and design perspective, this emerald cut bi color sapphire is an ideal engagement option for buyers who appreciate technical refinement and understated complexity. The emerald cut s long facets harmonize with settings that emphasize linearity, such as a four corner prong or a bezel with softened corners that protect the stone s profile while allowing the step facets to be read clearly. The sapphire s corundum hardness of nine on the Mohs scale provides excellent wearability for daily rings, and the stone s unenhanced Ceylon origin contributes to its collectible value. For clients who wish to customize, the stone responds well to settings that orient the longer axis along the finger, enhancing perceived length and elegance. At The Natural Sapphire Company we can provide detailed imagery, viewing videos under multiple light sources, and mounting options that preserve the stone s angles and polish, ensuring the finished engagement ring maintains the technical integrity and visual subtlety that characterize this rare bi color emerald cut sapphire.
