0.37 Ct. Greenish Yellow Sapphire from Madagascar

This transparent 0.37 carat round greenish yellow sapphire presents precise proportions and well executed finishing, measuring 4.26 x 4.26 x 2.83 millimeters with a mixed brilliant cut. The mixed brilliant faceting, combining a brilliant-style crown with a modified pavilion, optimizes light return and scintillation for a stone of this size, producing lively brilliance and pleasing dispersion. Color is medium intense with a distinct greenish yellow hue that reads evenly across the face up view, and the excellent polish contributes to strong surface luster and clean facet junctions. Clarity is graded as very very slightly included when evaluated at eye level, and the stone is transparent, allowing facets to interact clearly with incident light while maintaining an attractive, natural appearance. This sapphire originates from Madagascar and has been heat treated, a widely accepted enhancement to achieve stable, desirable color and to improve internal clarity.

The internal features of this sapphire, described here as inclusions, serve as natural identifiers that add character and provenance to the gem rather than diminishing its value. Observed inclusions are minor and consistent with natural corundum from Madagascar, including small pinpoint crystals and faint growth zoning that may appear as delicate linear features under magnification, and occasional tiny reflective platelets that contribute to subtle internal sparkle. These attributes act as a fingerprint for gemologists and are useful for identification, documentation, and matching when setting or pairing stones. The heat treatment applied to this sapphire is stable and customary in the trade and is disclosed to ensure full transparency in provenance and care. At The Natural Sapphire Company we record these characteristics to provide clear, factual information for gemological reference and practical use, enabling jewelers and clients to make informed decisions about mounting, care, and combination with other gems or metals. This sapphire is suitable for fine jewelry where a compact, color-forward stone is desired, and its documented inclusions and origin support both authenticity and natural character.
