1.09 Ct. Bluish Green Sapphire from Tanzania

This is a beautifully transparent 1.09 carat oval bluish green sapphire, precisely measured at 6.72 by 5.38 by 3.57 millimeters, presented by The Natural Sapphire Company. The stone is cut in an oval shape with a mixed brilliant cut, a classic choice that harmonizes the dynamics of light return with controlled color saturation. The mixed brilliant design places disciplined faceting on the crown to maximize brilliance, while the pavilion geometry supports a balanced color display, resulting in consistent visual appeal from every viewing angle. The proportions and dimensions give this sapphire an elegant face up presence suitable for a variety of fine jewelry settings, from a refined solitaire ring to an understated pendant where the gem can function as a focal point without overwhelming its mounting. At just over a carat, this sapphire offers an ideal balance between presence and wearability, fitting comfortably into both contemporary and traditional design languages.

The clarity is graded as very very slightly included when evaluated at eye level, which translates to an eye clean appearance for most observers. Under loupe magnification faint inclusions may be identified, as is consistent with natural corundum, but they do nothing to compromise the gem’s transparency or its capacity to interact with light. This degree of clarity is desirable to the informed buyer because it preserves the stone’s visual purity while still confirming its natural origin. The polish is excellent, which means facet junctions are crisp and surfaces are rendered with minimal polish lines. Excellent polish contributes directly to the gem’s brilliance and highlights the precision of the mixed brilliant cut, allowing light to enter and reflect with maximum efficiency. Taken together, the clarity grade and the polish quality ensure that the sapphire presents a luminous, evenly reflective surface, enhancing scintillation and delivering a lively appearance during movement.

Color is the defining characteristic of any sapphire, and this sapphire exhibits an intense bluish green hue that is both vivid and well saturated. The intensity of the color is strong without appearing overstated, which makes the gem versatile for different metal choices and settings, as it can be paired with yellow gold for warmer contrast or white gold and platinum for a cooler presentation. Importantly this sapphire has no enhancement, which is an increasingly rare attribute that speaks directly to its intrinsic value. Untreated sapphires command the attention of educated buyers because their color and clarity are natural, not the result of heat treatment or other modifications that can alter value. The origin is Tanzania, a country known for producing sapphires with a distinctive array of tones, from classic blue to greenish and parti colors, depending on geological conditions. Tanzanian sapphire occurrences, including well documented alluvial and primary deposits, produce material that is prized for its natural color variability and strong saturation, attributes that add provenance interest and collector appeal.

From a practical perspective this sapphire benefits from the inherent durability of corundum, which rates nine on the Mohs hardness scale, making it an excellent choice for daily wear with appropriate care. The mixed brilliant cut and the exacting polish make the stone highly adaptable to both protective and open settings, allowing jewelers to design pieces that emphasize the gem’s symmetry and brilliance while minimizing potential exposure to wear. For the purchaser focused on long term value, the combination of natural, untreated color, high clarity at eye level, excellent polish, and Tanzanian origin creates a compelling proposition, both aesthetically and as part of a curated collection.
