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

This gemstone is a transparent bi color sapphire weighing 1.12 carat, presented in a marquise shape with dimensions of 8.60 by 4.78 by 3.85 mm, and executed in a mixed brilliant cut that balances facet brilliance with an elongated silhouette. Clarity has been graded as very very slightly included at eye level, indicating that inclusions are minimal and do not interrupt the visual field when set. Color appears with medium intensity, showing a distinct two tone presence across the pavilion and crown, and the finish is an excellent polish that maximizes light return across the stone face. The stone has been heat treated in a controlled manner, a common enhancement for sapphires that improves color uniformity and stability, and the material is documented as originating from Ceylon Sri Lanka, a source long regarded for producing sapphires with attractive color and clean crystal structure. The proportions and cut yield strong scintillation for a marquise outline, and the elongated form translates to an elegant presentation in a variety of settings.

The bi color character of this sapphire is one of its defining attributes, producing a subtle but distinct shift in hue as the stone is viewed from different angles or placed against varying backgrounds. One facet plane leans toward a cool tone while another presents a warm golden cast, creating a composed interplay of color that reads differently in daylight and in artificial illumination. Because the gem is transparent and carries medium color intensity, it communicates both presence and refinement, avoiding heavy saturation while still maintaining noticeable color personality. The marquise cut accentuates the directional nature of the color zoning, and the mixed brilliant facet arrangement enhances fire and return, giving the stone a lively visual signature without sacrificing the clean, modern outline that makes marquise gems suitable for both solitary and multi stone designs.

Provenance and treatment details are central to long term value and care considerations, and this sapphire’s Ceylon origin and documented heat treatment inform both. Ceylon sapphires are prized for their clarity and color dynamics, attributes that contribute to collectibility and desirability over generations. Heat treatment, when performed properly, is stable and accepted throughout the trade, and it does not materially affect the inherent durability of corundum, which rates nine on the Mohs scale. That hardness ensures resistance to everyday abrasion, supporting wear in ring, pendant, or brooch applications if the mounting provides appropriate protection for the pointed ends of the marquise shape. Routine care is straightforward, it is best to cleanse the gem with warm water, a mild soap, and a soft brush, and to avoid harsh chemicals and prolonged exposure to extreme heat. Periodic professional inspection of the setting, ideally annually, will preserve the stone and its mount, and The Natural Sapphire Company can provide documentation and guidance to support long term maintenance and provenance records.

An heirloom piece is defined by enduring aesthetic, physical resilience, and provenance, and this marquise bi color sapphire meets those conditions in a way that supports intergenerational transfer. The stone’s balanced carat weight, refined proportions, and dual tone appeal create a piece that remains relevant across changing styles, while the fundamental toughness of sapphire secures its ability to be worn and enjoyed by successive owners. Thoughtful setting design will further enhance longevity, for example a bezel or secure prong gallery that protects the pointed ends, and a classic mounting rendered in durable metals will facilitate future resizing or repurposing without excessive loss of material. Documentation provided by The Natural Sapphire Company, including origin and treatment records, strengthens the gem’s story and market standing, which is important when communicating value and authenticity to heirs. With modest and regular care, professional cleaning, and retained paperwork that explains origin and treatment, this sapphire is a practical candidate to be passed down as a meaningful and lasting family asset.
