1.51 Ct. Greenish Blue Sapphire from Madagascar

This transparent 1.51 carat greenish blue sapphire presents a refined combination of measured proportions, precise cutting, and natural origin. The gem measures 7.67 by 6.07 by 4.64 mm, and its fancy shape is executed with a controlled step cut that emphasizes broad, linear facets and a measured pavilion depth. The color reads as greenish blue with an intense saturation that conveys depth and presence without appearing overly dark. The polish is excellent, resulting in crisp facet junctions and lively surface reflections that complement the step cut geometry. Origin is Madagascar, and this sapphire has not undergone any enhancement, a detail that preserves the stone as it formed in nature. The Natural Sapphire Company documents the no enhancement status, and the combination of weight, dimensions, and cut make this sapphire well suited to a bespoke setting where its unusual silhouette and saturated hue can be shown to advantage.

The clarity is graded as very slightly included when evaluated at eye level, a designation that indicates exceptional visual cleanliness paired with small internal features that do not distract from the gem s overall transparency. These inclusions are the stone s natural identifiers, and they add character rather than detract from value. Common inclusion types in sapphires from Madagascar include tiny mineral crystals, fine needlelike structures, and subtle growth zoning, and in this example you can observe minor internal features that are confined and well integrated with the crystal structure. Under magnification these inclusions provide a unique fingerprint for the sapphire, useful for identification and provenance, and they confirm the natural origin and the absence of filling or diffusion treatments. The presence of these stable, intrinsic features contributes to the gem s individuality, ensuring that it remains a singular example among sapphires of similar weight and color.

Practical considerations for use and care follow from the gem s robust hardness and the precise step cut. The sapphire s durability makes it suitable for daily wear when set with secure prongs or a bezel, and the even facet planes of the step cut favor settings that protect the edges while allowing light to enter and reveal the intense color. The greenish blue hue responds well to both warm and cool metal choices, and settings that allow viewing through the pavilion will accentuate the stone s depth and subtle color shifts. Because this sapphire has no enhancements, routine care is straightforward, with gentle cleaning by warm water, mild detergent, and a soft brush recommended, and professional inspection advisable for any pronged setting. At The Natural Sapphire Company we provide detailed information on origin, treatment status, and the measured characteristics of each stone, enabling informed decisions for design and purchase. This 1.51 carat fancy shape sapphire offers a rare combination of natural authenticity, distinctive inclusions that act as the gem s signature, and the precise cutting and polish that allow its intense greenish blue color to be appreciated in a wide range of jewelry applications.
