1.02 Ct. Pink Sapphire from Tanzania

This transparent 1.02 carat oval pink sapphire presents exacting gemological measurements, with dimensions of 6.43 x 4.95 x 3.34 mm, and a calculated depth of approximately 58.7 percent. The oval outline has been proportioned to maximize table area while retaining enough pavilion depth for effective light return, producing a pleasing face up size for its weight. Cut as a mixed brilliant, the stone combines a precisely faceted brilliant crown with a modified pavilion scheme, producing a harmonious balance between scintillation and color saturation. The gem exhibits intense color intensity, a medium to vivid tone that remains vibrant under a variety of lighting environments, and an excellent polish that yields crisp facet junctions and bright facet reflections. Origin is Tanzania, and there has been no enhancement, a combination that places this sapphire in a category prized by collectors and designers who value natural color integrity and documented provenance.

The mixed brilliant faceting strategy applied to this oval is executed to technical standards, with careful attention to crown angle relationships and pavilion geometry to optimize return of incident light. The brilliant crown disperses light into defined flashes, while the modified pavilion facets control the path of light to minimize leakage and enhance face up brightness. The result is a stone that shows lively scintillation when viewed in motion, paired with strong overall brilliance from both direct and reflected light. The faceting layout also contributes to even color distribution across the table, preventing common issues of dark or washed out areas. Excellent polish heightens contrast between light and dark facets, improving the perception of depth and the apparent saturation of the intense pink hue. For makers seeking predictable optical performance when set, this cutting approach affords consistent sparkle without aggressive windowing, an important consideration for fine jewelry applications.

Clarity is graded as very slightly included at eye level, meaning that inclusions are minimal and do not detract from the gem’s visual appeal or structural integrity. Typical inclusions in sapphires of this clarity range include fine needle like crystals or minute pinpoint crystals, often arranged in discrete locations rather than pervasive clouds. In this specimen these features are sufficiently sparse and small that the gem remains fully transparent to the unaided eye, allowing the intense pink color to read clearly through the table and crown facets. The lack of enhancement is significant, as it preserves the original lattice structure and mechanical behavior of the corundum, and avoids the potential long term stability issues associated with some treatments. Surface condition is excellent, with well executed facet transitions and no signs of polishing pits or abrasions, which further affirms the gem’s readiness for immediate setting and wear.

From a practical perspective the durability profile of this Tanzanian pink sapphire makes it exceptionally well suited for daily wear in fine jewelry. As corundum, sapphire rates 9 on the Mohs hardness scale, rendering it second only to diamond for resistance to abrasion, and its trigonal crystal structure lacks true cleavage, reducing susceptibility to catastrophic splitting under normal use. The combination of high hardness and robust toughness means that with appropriate setting choices the stone can be used for engagement rings, daily worn pendants, and secure stud settings with confidence. For the most active daily wear scenarios a protective bezel or secure four or six prong mounting with well designed prong heads at the longer and shorter axis points will shield the girdle and corners of the oval from incidental knocks. Routine care is straightforward, using warm soapy water and a soft brush, and periodic professional inspection to confirm secure setting is recommended. At The Natural Sapphire Company we provide detailed documentation of the gem’s properties, and we are available to advise on setting styles and maintenance protocols to ensure that this untreated, intensely colored pink sapphire offers both lasting beauty and reliable performance in everyday jewelry.
