1.09 Ct. Bi Color Sapphire from Madagascar

This 1.09 carat oval bi color sapphire is a transparent, eye catching gem with precise dimensions of 7.10 x 5.18 x 3.14 mm, a mixed brilliant cut that balances scintillation and color display, a clarity graded as very slightly included when evaluated at eye level, a medium intense color intensity, and an excellent polish. This sapphire is offered by The Natural Sapphire Company, and it is important to note that it is unenhanced, a natural, untreated stone that speaks directly to collectors and connoisseurs who value geological authenticity. The mixed brilliant cut used on this oval shape optimizes both brilliance and color return, producing lively faceting at the crown while preserving the gem material and the integrity of the bi color zoning. The dimensions are ideal for a ring center stone, pendant, or a bespoke piece that can showcase the shifting palette of hues that define a bi color sapphire, and the transparency ensures a clean face up appearance that lets the internal color structure be appreciated without cloudiness.

To understand why this piece is appealing to an educated buyer, consider the grading aspects in practical terms. The carat weight of 1.09 places the gem in a size range that offers presence on the finger without the structural compromises that sometimes accompany larger sapphires. The measurements of 7.10 x 5.18 x 3.14 mm indicate a proportional oval with sufficient depth to maintain strong color saturation while offering an attractive face up area. The mixed brilliant cut combines aspects of both brilliant and step cutting, which translates to lively light performance and disciplined color distribution, qualities that are particularly beneficial for bi color material where both hue contrast and light return must be balanced. Medium intense color intensity signals a robust saturation that is neither washed out nor overly dark, a sweet spot for both aesthetic appeal and market desirability, and the excellent polish enhances luster and reduces light leakage at the surface, contributing to a gem that reads bright and refined under diverse lighting conditions.

Clarity and origin are central to the gemological value of this sapphire, and the clarity description very slightly included when evaluated at eye level is meaningful in everyday use. In simple terms this denotes minor internal characteristics that are small and unobtrusive, typically requiring careful inspection or magnification to fully resolve, and they do not interrupt the gem s transparency or distract from its visual charm when set and viewed in normal situations. Such clarity is consistent with natural sapphires, which often show minute mineral inclusions or silk features that can act as fingerprints indicating natural formation. The absence of enhancement is a significant differentiator, as unheated sapphires command a premium because the color and clarity are wholly natural, preserved from formation to setting. Origin from Madagascar further enhances provenance, Madagascar being a source of remarkably diverse and high quality sapphire material, known for elegant color ranges and vivid crystallization zones. For a buyer who values traceable origin and unaltered natural character, provenance from Madagascar combined with unenhanced status underscores both rarity and authenticity.

Beyond technical grading, this sapphire has clear attributes that make it an exceptional candidate for a generational heirloom piece. Sapphire ranks nine on the Mohs scale, a hardness that confers exceptional resistance to scratches and wear, making it ideal for daily wear settings such as engagement rings that are intended to be passed down intact. The bi color nature of the stone makes it visually unique, a conversation starting focal point with subtle color transitions that will evoke memory and narrative across generations, while the mixed brilliant cut and excellent polish mean the gem will retain visual impact with regular maintenance. Because the stone is unenhanced, its value narrative is straightforward and enduring, there is no dependency on post mining treatments that can complicate valuation, and an unheated, well documented gem from Madagascar is a tangible asset that often appreciates with provenance and time. With prudent settings that protect the girdle and culet, periodic professional cleanings, and the maintenance of documentation from The Natural Sapphire Company detailing origin, weight, cut, clarity, and absence of enhancement, this sapphire can be entrusted as a family heirloom that conveys both tangible worth and personal story.
