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

One transparent, oval shape, bi color sapphire weighing 1.44 carats is presented with precise proportions of 8.12 by 5.96 by 3.87 millimeters, offering a classical oval silhouette with modern versatility. The gem displays an intense color intensity that shifts attractively between golden yellow and cornflower to deep blue depending on orientation, a characteristic that makes this stone visually compelling and rare. Cut as a mixed brilliant, the faceting scheme combines a brilliant facet pattern on the crown with step or geometric facets on the pavilion, creating a balance between scintillation and depth, and allowing the two dominant colors to interact across the table and pavilion. The transparency is described as clear, and the polish is excellent, translating to crisp facet junctions and lively light return. As a bi color sapphire from Ceylon, this stone exhibits the kind of saturated yet complex hue patterns prized by collectors and connoisseurs, providing both eye appeal and design flexibility for bespoke jewelry, and at The Natural Sapphire Company we present it as a collectible gem that performs beautifully in rings, pendants, and bespoke settings.

From a gemological and valuation perspective, this sapphire is notable for attributes that educated buyers seek, clarity being a central aspect. The clarity grade is recorded as very very slightly included when evaluated at eye level, which indicates that inclusions are minimal and do not materially detract from the gem's overall transparency or brilliance when set. This level of clarity supports strong light performance and contributes to the stone retaining high visual purity under normal viewing conditions. The excellent polish further enhances apparent clarity, ensuring that light travels cleanly through the pavilion and returns to the observer with minimal diffusion. Origin influences value, and this sapphire is from Ceylon, a source with a long established reputation for producing sapphires with lively, often velvety tones and strong pleochroic behavior. The gem has been heat treated, a standard and widely accepted enhancement within the trade, applied to improve color uniformity and clarity. Heat treatment is considered stable and permanent when properly performed, and it is disclosed here because transparency about enhancements is essential for accurate valuation and for the informed buyer who may consider resale, insurance, or certification options.

Considering rarity and market desirability, the bi color nature of this sapphire adds a layer of scarcity relative to single tone stones, particularly when the color transition is as distinct and attractive as in this specimen. Bi color sapphires from Ceylon with intense color intensity and high polish are sought after by collectors because they combine aesthetic uniqueness with the traceable provenance associated with Sri Lankan material. For an educated buyer, factors that increase value include the balance of hue and saturation, the evenness of color transition, the precision of the mixed brilliant cut which affects light performance, and the clarity grade which minimizes the need for further treatment. At The Natural Sapphire Company we emphasize accurate documentation and honest disclosure, because these elements support long term value retention. This sapphire represents a strong proposition for someone seeking a gemstone that is both wearable and investable, offering the visual drama of color change with the reliability of a well executed cut and finish.

Durability is a practical concern for everyday jewelry, and on the Mohs scale this sapphire ranks at nine, second only to diamond which ranks at ten. This high hardness means that the surface is highly resistant to scratches from almost all everyday materials, making it an excellent choice for rings and other jewelry subject to regular wear. Hardness is one aspect of durability, and sapphires also have good toughness as corundum, lacking the perfect cleavage that would make them prone to splitting under light, directional impact. Nevertheless, like all gemstones, they can chip if struck sharply on a facet edge or exposed to severe impacts, so secure settings that protect the girdle and corners are recommended. For longevity we advise bezel, half bezel, or protective prong settings for high wear pieces, routine inspections of mounting integrity, and avoidance of hard knocks. Routine cleaning with warm soapy water and a soft brush will maintain brilliance, while exposure to strong chemicals should be avoided. This Ceylon bi color sapphire, presented by The Natural Sapphire Company, therefore combines collector grade aesthetics with professional level durability, making it a well balanced choice for both fine jewelry use and discerning gemstone collections.
