0.58 Ct. Bi Color Sapphire from Madagascar

This transparent 0.58 carat fancy shape bi color sapphire is a refined example of natural gem quality, with exact dimensions of 6.88 by 3.58 by 2.82 millimeters. The stone has been given a step cut to emphasize clarity and color separation, and it carries a clarity grade of very very slightly included, evaluated at eye level by our gemologists. Color intensity is described as medium intense, which in a bi color sapphire allows both hues to be perceptible without overpowering one another. The gem has an excellent polish, and it is important to note that there has been no enhancement. Origin is Madagascar, a source known for producing a broad spectrum of sapphire colors. These specific facts matter for an educated buyer because they define how the sapphire will perform in light, how it will wear over time, and the degree to which its natural properties contribute to rarity and value.

For buyers accustomed to gemological terminology, the clarity grade of very very slightly included, evaluated at eye level, communicates that the inclusions are minimal and unobtrusive in face up view. Such clarity is desirable in transparent stones and especially significant in a bi color sapphire where inclusions can interfere with the perception of two distinct colors. The step cut is a deliberate choice for this material. Unlike brilliant cuts that prioritize sparkle, a step cut creates broad facets that showcase color planes and internal structure, making it ideal for accentuating the bi color effect while maintaining a classic, elegant profile. At 0.58 carat and the given proportions, the stone sits in a size range that balances wearability and presence, allowing it to be set in a range of fine jewelry styles without compromising the visual impact of the color transition. The medium intense color intensity signals a saturated yet balanced appearance, a factor that informed collectors and designers recognize as a sweet spot for long term desirability.

This sapphire is especially valuable because it is natural and untreated. In the modern market, untreated material from reputable origins commands a premium, because enhancements such as heat treatment alter a stone in ways that change both its appearance and its market perception. Madagascar is an increasingly important source in the global sapphire trade, supplying material that ranges from pastel tones to deeply saturated hues, often with interesting color zoning and pleochroic properties. The combination of origin, no enhancement, pleasing clarity, and a cut tailored to the gem's internal characteristics makes this piece notable. From a technical perspective, the interplay between facet orientation and the gem's internal color distribution is what creates the pleasing bi color effect in the finished stone. For an educated buyer, the knowledge that this stone presents medium intense color and excellent polish without any artificial modification is central to assessing long term value, collectability, and compatibility with heirloom quality jewelry design.

The journey of this stone from Madagascar to The Natural Sapphire Company embodies careful selection and skilled craftsmanship at each stage. The rough was identified in private workings and artisan operations in Madagascar, where experienced local miners recover sapphire rough from alluvial gravels and secondary deposits. After initial sorting for clarity and potential color, the rough was selected for cutting by a lapidary who specializes in retaining natural color zoning. The cutter chose a step cut intentionally, to maximize the visual balance between the two colors and to preserve weight while creating broad facets that enhance the stone’s transparency and polish. After preforming and faceting, the gem received an intensive hand polish, which resulted in the excellent surface finish that contributes to light return and overall appeal. Upon completion, our in house gemologists examined the stone to confirm weight, measurements, clarity grade, and the absence of enhancement. The Natural Sapphire Company takes responsibility for detailed documentation and provenance, and we present this sapphire with a clear description of origin and characteristics so that buyers can make an informed decision founded on verifiable details. For connoisseurs and designers who value natural color expression, ethical sourcing, and expert cutting, this 0.58 carat bi color sapphire offers a rare combination of aesthetic charm and gemological integrity.
