0.42 Ct. Bluish Green Sapphire from Madagascar

This listing describes a natural, transparent, pear shape bluish green sapphire, weighing 0.42 carat, with exact dimensions of 5.58 x 3.69 x 2.65 mm, cut in a mixed brilliant style, and finished with an excellent polish. Clarity is graded as very very slightly included, evaluated at eye level, indicating that inclusions are minimal and require careful inspection to detect without magnification. Color intensity is medium, with a balanced blend of blue and green tones that present a distinct bluish green appearance when viewed under neutral lighting. The stone shows no enhancement, it is untreated, and its origin is Madagascar, a locality noted for producing sapphires with refined color varieties and stable crystalline properties. The compact pear silhouette demonstrates economical material use with an emphasis on optical performance, and the mixed brilliant cut has been executed to provide lively light return and controlled dispersion, while the excellent polish enhances brilliancy and surface consistency.

The rarity of this sapphire arises from a convergence of attributes that are uncommon in comparable stones, both in size and in color. In the 0.40 carat class, faceted sapphires most frequently present as conventional blues or as more heavily included specimens that require clarity concessions or surface treatments to achieve marketable appearance. A transparent, untreated example of 0.42 carat weight retaining a medium, uniform bluish green hue is significantly less common, because the dual tone requires precise trace element chemistry and uniform crystal zoning during growth. When compared to more prevalent blue or heavily green sapphires, this stone occupies a narrower intersection of desirable parameters, combining transparency, minimal inclusions, a well centered pear outline, and a middle intensity bluish green tone. The mixed brilliant cut further differentiates this gem from similarly sized step or standard brilliant cuts, as it is specifically chosen to enhance color saturation while preserving brilliance, a balance that is technically exacting at this small scale. Madagascar origin contributes to its rarity profile, as the region produces a wide spectrum of sapphire colors, but specimens that remain wholly untreated, show superior polish, and maintain such clarity at this size are only a small portion of output.

Practical considerations for use and valuation reflect the stone s inherent scarcity and technical quality. At 0.42 carat and with the measured dimensions provided, the sapphire adapts well to a range of jewelry applications where precision settings are required, including fine solitaire pendants, accent stones in bespoke engagement rings, or as a paired accent in asymmetric designs, while its pear shape allows for elegant orientation in elongated settings. The combination of medium intense bluish green color, excellent polish, and very very slight inclusions evaluated at eye level will influence both aesthetic impact and pricing relative to more common blue or treated stones of similar carat weight. This sapphire is presented through The Natural Sapphire Company, and detailed imagery, measurement documentation, and independent testing information related to enhancement status and origin are available upon request, to assist in appraisal and setting decisions. For clients seeking a compact, natural, untreated sapphire with a distinctive bluish green hue and professional finish, this example provides a precise, rare option that aligns with exacting standards of gemological quality.
