1.09 Ct. Bi Color Sapphire from Madagascar

This 1.09 carat oval shape bi color sapphire is a finely balanced gem that combines visual intrigue with precise gemological attributes. Measuring 6.79 x 5.09 x 4.13 mm, this sapphire displays a pleasing oval proportion that is slightly elongated, a profile that flatters settings on a range of jewelry types. The stone is transparent, with a mixed brilliant cut that blends faceting styles to optimize both color and brilliance. Its clarity is described as very very slightly included, as evaluated at eye level, which for a discerning buyer translates to an eye clean appearance with only minute internal features visible under close inspection. Color is medium intense in intensity, providing vivid presence without overwhelming saturation, and the polish has been graded excellent, allowing the reflected light to return with crispness and contrast. There has been no enhancement to this sapphire, the natural state of the material preserved from rough to finished gem, and its origin is Madagascar, a region known for producing a wide spectrum of high quality sapphires. As representatives of The Natural Sapphire Company we present this gem with full transparency about its characteristics, so an educated buyer can weigh its optical appeal and market significance with confidence.

The geometric faceting of this mixed brilliant cut is designed deliberately to allow maximum light play. The mixed brilliant approach typically combines a step cut on the pavilion with brilliant style facets on the crown, or vice versa, depending on the cutter s intention to balance color distribution with sparkle. In this oval bi color sapphire the arrangement of crown facets disperses incoming light into scintillation and fire, while the pavilion facets act as reflective planes that return that light efficiently to the eye. The result is an engaging interplay of bright flashes and color zoning that changes with movement, revealing the bi color character in a dynamic way. Precision in facet junctions and symmetry are critical to maximize light return, and the excellent polish on this stone ensures facet surfaces are mirror clean, minimizing light leakage and promoting crisp scintillation. For the informed buyer the technical merit of this cut is important, because it affects not only immediate visual performance, but also how the gem behaves in different mounting orientations and under various lighting conditions, from daylight to indoor illumination.

Clarity and treatment history are central to assessing both aesthetic quality and long term value, and this sapphire performs strongly on both counts. Very very slightly included at eye level means the stone reads as essentially eye clean, with internal features that are minimal and do not detract from overall appearance. Because those inclusions are small and well positioned, they do not interfere with the stone s ability to transmit and reflect light, which complements the mixed brilliant faceting to produce lively brilliance. Importantly, the stone has undergone no enhancement, a notable factor in market desirability because many commercial sapphires are heat treated to improve color and clarity. A natural, unenhanced sapphire from Madagascar carries particular interest, given the island s geological conditions that produce sapphires with attractive color range and strong crystal quality. Madagascar has become a respected source for collector grade sapphires, and provenance from this locale can support both the aesthetic story and the intrinsic value of the gem. The Natural Sapphire Company maintains rigorous standards when sourcing, and full disclosure of treatment and origin is integral to our practice.

For the educated buyer evaluating this sapphire for investment or a bespoke commission, the combination of attributes here is compelling. The 1.09 carat weight and the 6.79 x 5.09 x 4.13 mm dimensions create an adaptable size that works beautifully in rings, pendants, or as the centerpiece of a custom creation, while the oval shape provides elegant visual elongation on the finger. The mixed brilliant faceting and excellent polish ensure the piece will perform under varied lighting conditions, offering scintillation and color play that highlight the bi color phenomenon. The very very slightly included clarity, together with the absence of enhancement, places this stone in a favorable position within the market segment for natural sapphires, appealing to buyers who prioritize untreated material and documented provenance. If desired, we can arrange independent grading, imaging, and advice on settings that will maximize face up color and durability. At The Natural Sapphire Company we are available to discuss certification options, recommended mounting styles to showcase the bi color dynamics, and comparative market context, so you can make an informed decision about adding this distinctive Madagascar sapphire to your collection or design project.
