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

If you have been searching for a truly singular sapphire that ends your search for either the perfect engagement ring center or a rare addition to a collector cabinet, this cushion shaped bi color parti sapphire is the answer you have been waiting for. We understand that buyers of special gemstones look for a combination of size, color character, and trustworthy origin, and this gem delivers on every front. At 1.58 carats and measuring 7.02 x 5.42 x 4.95 mm, this stone sits in a rare size class for parti sapphires, where most examples tend to be smaller and less commanding. Its cushion shape gives a classic, elegant silhouette that suits both vintage inspired and contemporary settings, and the mixed brilliant cut brings modern sparkle into the traditional form. When your priority is to secure a stone that stands apart in a sea of similar listings, this sapphire checks that box decisively.

Color is the heart of what makes parti sapphires collectible, and this stone exhibits a bi color presence that feels both dramatic and refined. Evaluated at medium color intensity, the sapphire shows an appealing interplay between deep blue and olive green tones that shift with viewing angle and light source. This kind of balanced color zoning in a stone of this size is uncommon, especially with the transparency and polish that allow the color to breathe and play rather than be obscured. The term parti describes the visible partition of color, and here the distribution is artful and dynamic. For a bride seeking a ring that announces individuality without sacrificing wearability, or for a collector who prizes uncommon color pairings from classic sources, this sapphire offers a rare visual personality that is difficult to find in comparable stones.

Beyond its aesthetic qualities, this sapphire offers the technical credentials that serious buyers require. It is faceted with a mixed brilliant cut that maximizes light return while preserving color windowing and body. The clarity grade is slightly included, evaluated at eye level, which in sapphires often means natural inclusions that affirm authenticity without detracting from overall beauty. The polish on the facets is excellent, ensuring crisp facet junctions and lively reflections. Origin is Ceylon Sri Lanka, a source historically celebrated for producing sapphires with exceptional color character and clarity, and provenance is a meaningful factor for collectors and those commissioning bespoke jewelry. This sapphire has been heat treated, which is a stable and widely accepted enhancement that optimizes color and clarity. Heat treatment performed to accepted standards preserves durability and is commonly disclosed to maintain full transparency with the buyer.

When you choose this stone from The Natural Sapphire Company you gain more than a gemstone, you gain certainty. For an engagement ring this sapphire offers everyday resilience on account of sapphire hardness, and the cushion shape and dimensions are ideal for settings that protect the stone while showcasing its parti color play. For the collector, the combination of a rare carat weight for a parti sapphire, the pleasing medium intensity of color, the excellent polish, and Ceylon provenance creates a specimen that belongs in a curated selection. Our team can advise on setting styles that enhance the color split, and we provide gemologic information with every purchase so your confidence in the stone matches the confidence you will feel wearing it.
