1.55 Ct. Bi Color Sapphire from Madagascar

This exceptional heart shape bi color sapphire weighs 1.55 carat and measures 6.09 x 7.17 x 4.89 mm, a proportion that balances wearability with presence. The mixed brilliant cut has been executed to maximize return of light and to emphasize the stone's bi color nature, allowing zones of blue and green to sit side by side with lively interplay as the gem moves. The gem is transparent, with intense color intensity and an excellent polish, attributes that contribute directly to visual appeal and to market value. The clean heart shape is a specialist cut that demands skill to preserve color zoning and clarity while producing symmetrical lobes and a well defined cleft, making this piece both a technical achievement and an attractive center stone for bespoke jewelry.

From a gemological perspective this sapphire is noteworthy on several fronts. The clarity grade is very very slightly included evaluated at eye level, indicating that inclusions are minimal and do not detract from the gem when viewed unaided. For an educated buyer clarity of this standard in a colored stone of perceptible color zoning is an important premium attribute, because it combines transparency with natural character. The lack of enhancement is particularly significant, untreated sapphires are rarer in the market and command higher buyer confidence and long term value, as they reflect natural color and stability. The origin is Madagascar, a source that has produced many high quality sapphires in recent decades, and provenance from this island can be an advantage because it links the gem to known geological conditions that yield strong color and good crystal quality. The excellent polish and the mixed brilliant pavilion ensure that light performance is optimized, supporting the perception of depth and vibrancy across the bi color field.

As an investment grade collectible this heart shape bi color sapphire offers several favorable characteristics that support future appreciation potential. First, rarity factors are aligned, a well cut heart shaped sapphire of 1.55 carat with intense natural bi color, transparent clarity, and no enhancement is uncommon in the wholesale and retail markets. Second, market demand for unique natural stones has been growing as collectors and private investors diversify beyond traditional asset classes, and untreated colored gemstones from reputable sources have shown resilience and selective price appreciation. Third, the gemological quality elements that matter to discerning buyers are all present here, including a recognized origin, strong polish, and a clarity grade that promotes resaleability. For those considering the piece as part of a diversified gem portfolio liquidity is aided by the stone size and shape, which suits both bespoke jewelry commissions and collector cabinets. While no investment can be guaranteed, historically, high quality, untreated sapphires from known origins have retained and in many cases increased in value over time as supply of comparable material remains constrained and well documented examples become more sought after.

When evaluating acquisition and future value it is prudent to consider certification, conservation of provenance, and responsible documentation, and The Natural Sapphire Company stands behind thorough gemological reporting and transparent origin information for this sapphire. Proper certification from an independent laboratory will enhance marketability, and professional mounting that preserves weight and symmetry will protect intrinsic value. For collectors interested in the aesthetic and the asset story this bi color heart shaped sapphire offers a rare combination of beauty and technical merit, making it a compelling choice for investment minded buyers who value natural, untreated origin, and meticulous cutting and polishing.
