1.59 Ct. Green Tourmaline from Tanzania

This 1.59 carat radiant shape green tourmaline from Tanzania presents an exceptional combination of measured proportion and optical clarity, making it a superior choice for discerning buyers. The stone measures 7.92 x 6.22 x 4.03 mm, producing an approximate depth of 4.03 mm which yields a depth ratio of about 57 percent, a proportion that balances table size and pavilion depth to optimize light return. The radiant cut employed here merges the geometric stability of a rectangular outline with a sophisticated faceting scheme that combines step facets on the crown with brilliant facets on the pavilion, resulting in strong internal reflection and scintillation. The cutter has maintained excellent symmetry across the faceting pattern, ensuring even light performance from corner to corner, and the polish is graded excellent, permitting clean facet junctions and crisp facet planes that maximize the gem s transparency and surface luster.

Color characteristics for this specimen are described as light color intensity with a clear green hue that reads fresh and lively in hand. The lighter tone allows for a high degree of transparency which enhances the movement of light through the pavilion facets, producing a bright, airy appearance rather than a deep saturated body color. Under variable lighting conditions this green tourmaline exhibits uniform color distribution with minimal windowing thanks to the careful balance of the table and pavilion proportions. For collectors and designers who prioritize color accuracy, the light intensity offers versatility for pairing with a range of metal colors, as the green maintains presence without overpowering delicate settings or adjacent gemstones.

Clarity and enhancement status are paramount for technical buyers, and this tourmaline carries a clarity grade of very very slightly included when evaluated at eye level, with no enhancement applied. The inclusions are minute and do not compromise the stone s transparency or affect its brilliance at typical viewing distances. Absence of heat or irradiation treatments preserves the natural pleochroic characteristics and structural integrity of the crystal, attributes that sophisticated clients often require. The origin, Tanzania, is noted for producing tourmalines with fine crystalline quality, and in this example the natural origin complements the gem s untreated status, offering provenance that supports both collector value and design integrity.

From a practical mounting and design perspective, the radiant shape with truncated corners delivers both aesthetic and structural benefits. The rectangular outline and proportional length to width ratio provide an elegant visual elongation when set in a ring, while the truncated corners reduce the risk of chipping and allow for secure four prong settings without sacrificing the gem s architectural silhouette. For solitaire rings a medium to delicate bezel can protect the girdle while still exposing ample crown to exhibit the faceting brilliance, and as a center stone in halo or three stone compositions the light green hue pairs beautifully with diamonds or warm metal accents. At The Natural Gemstone Company we emphasize accurate measurement and transparent grading, and this Tanzanian radiant tourmaline is presented with specifications that assist jewelers and connoisseurs in making informed design choices, whether the intent is bespoke high end jewelry or an elevated everyday piece.
