1.15 Ct. Blue Sapphire from Tanzania

This sapphire is a transparent, pear shaped gem weighing 1.15 carats, with dimensions of 6.47 x 6.71 x 3.39 mm, a mixed brilliant cut, and an excellent polish. The clarity is graded very very slightly included, evaluated at eye level, indicating that inclusions are minimal and do not impact the stone in normal visual inspection. The color presents as vivid blue, and importantly, there has been no enhancement. The material comes from Tanzania, a source known for producing sapphires with dynamic color and good crystal quality. The combination of a clean, vivid stone and the absence of treatments makes the specimen straightforward to evaluate and desirable to collectors and designers who prioritize natural state and traceable origin.

The weight of 1.15 carats is a central attribute that affects both the gem’s visual presence and its market value. Carat weight in corundum translates directly to mass, with one carat equal to two tenths of a gram, and increases in weight are not linear in supply. Small increases in carat weight move a stone into incrementally less common categories, and a well colored, eye clean sapphire just above one carat is materially rarer than many sub one carat counterparts. This rarity is compounded when clarity remains at a very very slightly included level, when color intensity is vivid, and when no enhancement has been applied. In practical terms the 1.15 carat weight provides sufficient size to act as a prominent center stone in a variety of settings, while retaining the gemological qualities that allow it to command stronger per carat pricing than more common, lower weight material.

The pear shape and mixed brilliant cut influence how that 1.15 carat weight reads face up and how light is returned to the viewer. A mixed brilliant faceting scheme is designed to balance scintillation and color delivery, allowing the mass of the stone to be distributed in a way that maximizes the apparent size and the saturation of blue within the table area. The exact dimensions of 6.47 x 6.71 x 3.39 mm show a compact pavilion depth and a well considered outline, which helps preserve weight while producing a pleasing silhouette for ring settings, pendants, or bespoke designs. Excellent polish ensures minimal light scatter at facet junctions, which in turn enhances both brilliance and perceived color depth. Taken together, weight, cut, and finish determine the face up performance, and in this specimen those elements are aligned to make efficient use of the 1.15 carat mass.

Provenance and treatment status further define the stone’s market position, and this sapphire, sourced from Tanzania, is offered without enhancement. Untreated blue sapphires with vivid color and high clarity are comparatively uncommon, and the absence of heat treatment or other modifications preserves the natural crystal characteristics that connoisseurs and specialists value. The clarity designation of very very slightly included, evaluated at eye level, denotes that inclusions are only detectable under magnification or upon careful scrutiny, which supports both visual purity and durability. The Natural Sapphire Company provides accurate gemological measurements, including the stated dimensions and carat weight, and documents the cut, clarity, color intensity, origin, polish, and enhancement status to allow informed assessment. This 1.15 carat pear shaped, mixed brilliant cut, vivid blue sapphire represents a measured balance of weight, optical performance, and natural provenance, suitable for settings where the interplay between size and intrinsic gem quality is a primary consideration.
