1.61 Ct. Yellowish Green Sapphire from Tanzania

This transparent cushion shape yellowish green sapphire weighs one point six one carat, and measures six point four eight by five point five seven by four point eight three millimeters, making it a compact gem with a commanding presence for its size. Sourced from Tanzania, this stone arrives to you in wholly natural condition, with no enhancement, and an intense color intensity that reads clearly to the eye. The Natural Sapphire Company presents this crystal as an example of careful material selection, where rough orientation and rough clarity were chosen to allow a mixed brilliant faceting scheme to deliver both scintillation and color depth. The overall appearance is transparent with a lively face up presence, suitable for use as a primary center stone in a ring, pendant, or bespoke commission where clarity of color and refined cutting are priorities.

The cutting is faceted with a mixed brilliant paradigm, combining a brilliant style crown with a pavilion arranged to retain weight while optimizing return of light. The cushion outline is gently rounded at the corners, with pavilion facet planes meeting a well defined culet area that supports controlled light leakage to produce flashes of white light and colored sparkle. Crown angles were executed to a moderate height, with a table proportion that balances fire and color, avoiding an overly large table that would wash the hue, and avoiding an overly small table that would fragment the visual field. Facet junctions are crisp and well defined, and the polish is excellent, producing mirror like facet surfaces that maximize internal reflections and deliver tight scintillation. The mixed brilliant design in this specimen emphasizes center brightness with complementary peripheral flashes, a feature that allows the stone to read larger than its measured carat weight when set face up.

Color and clarity characteristics work together in this sapphire to produce a sophisticated visual result, the hue settling into a yellowish green territory with intense saturation, the visual impression alternating between fresh green and warm yellow green depending upon viewing angle and lighting. This sapphire displays subtle pleochroic contrast, with the most saturated planes showing deeper green, and orthogonal directions revealing brighter yellow green, a trait that a skilled cutter has oriented to favor face up intensity. The clarity grade is slightly included when evaluated at eye level, with small internal features that are localized and do not compromise overall transparency or light performance. These inclusions are typical of natural materials, they serve as fingerprints of origin, and in this stone they remain unobtrusive, often masked by facet reflections, while contributing to the gemological traceability that discerning collectors value. The excellent polish and careful symmetry minimize any visual distraction from inclusions, and the girdle consistency supports secure mounting without requiring excessive metal.

As a centerpiece, this cushion sapphire offers a refined combination of technical craftsmanship and natural character, its mixed brilliant faceting producing a rhythmic scintillation that anchors a composition, while the intense yellowish green palette provides an uncommon yet versatile tone that pairs well with both warm and cool metals. The size and proportions make this gem suitable for a solitaire setting with protective prongs, or for a halo composition where surrounding smaller stones increase perceived size without diluting the central color. For collectors who appreciate traceable origin and untreated material, this Tanzanian sapphire represents an attractive addition, and The Natural Sapphire Company stands ready to provide detailed imaging, gemological documentation, and bespoke setting proposals to ensure the stone achieves its full potential in wearable form.
