1.60 Ct. Yellowish Green Sapphire from Tanzania

This transparent 1.60 carat oval yellowish green sapphire presents a balanced combination of measured proportions and vivid color, making it an excellent specimen for collectors who seek refined material with natural character. The gem measures 7.51 x 5.79 x 4.20 mm and has been faceted in a mixed brilliant cut to optimize both color saturation and light return. Clarity is graded as slightly included when evaluated at eye level, allowing the stone to maintain a clear and lively face up appearance while retaining the natural inclusions that affirm its origin. Color intensity is described as intense, with an even distribution of yellow and green tones across the crown and pavilion that produce a sophisticated, forest like hue. The polish is excellent, enhancing facet contrast and surface luster, and there has been no enhancement applied to this sapphire, preserving its natural state and intrinsic attributes. Origin is Tanzania, which adds provenance that is of interest to discerning collectors and connoisseurs.

The mixed brilliant cutting style enhances the gem to display both scintillation and depth of color, with a faceting scheme that balances broad flashes from the crown with smaller, bright facets on the pavilion. When viewed face up the table reveals concentrated color, while subtle shifts in tone become visible as the stone is tilted, illustrating pleochroic tendencies typical of corundum in this color range. The proportions yield a pleasing profile, with the measured depth of 4.20 mm producing an overall depth that is approximately sixty three percent of the average girdle diameter, a proportion that supports strong light performance without sacrificing weight or durability. Under daylight the yellowish green leans toward a clear, lively green, while under warmer light the stone can take on more yellow or olive notes, offering visual versatility for a range of design contexts. The result is a sapphire that reads as rich and nuanced in a gallery setting, while remaining practical and wearable in everyday jewelry.

From a clarity and craftsmanship perspective this sapphire demonstrates careful cutting to maximize optical return while respecting the integrity of the rough. Slight inclusions are present at eye level, yet they do not materially detract from brilliance or color. Slight inclusions can serve as fingerprints for provenance and age, and for many collectors they add to the character and natural authenticity of the piece. The excellent surface polish enhances durability at the facet junctions and creates crisp facet outlines that contribute to lively reflections. Sapphire is a durable gem for jewelry, with a Mohs scale rating of nine, which ensures that well set pieces can be worn regularly with appropriate care. The natural, untreated status increases its appeal for a high end collection, since untreated sapphires with strong color and good clarity are comparatively rare in the marketplace.

This 1.60 carat Tanzanian sapphire is well suited to a variety of high end settings, and its oval shape and balanced proportions make it adaptable to classic solitaire mounts, elegant halo designs, or bespoke pieces where the stone serves as the focal element. For collectors seeking material that combines aesthetic distinction with investment quality, this sapphire presents a compelling option, due to its intense natural color, fine polish, and unenhanced condition. The Natural Sapphire Company offers this gem with supporting information about its measured attributes and origin, and can assist with photographic documentation and independent gemological reports upon request. For curators of high end collections who value traceable origins, natural treatment status, and thoughtful cutting, this Tanzanian yellowish green sapphire makes a refined addition that complements both historical pieces and contemporary designs.
