0.31 Ct. Green Tourmaline from Tanzania

This 0.31 carat green tourmaline, presented by The Natural Gemstone Company, is a transparent cushion shape measuring 5.21 by 3.93 by 2.34 millimeters, cut in a mixed brilliant style that balances scintillation and depth, with a clarity grade of slightly included when evaluated at eye level, an intense color intensity, and an excellent polish. The mixed brilliant cutting style combines a faceting scheme that emphasizes both table and pavilion brilliance, allowing this gem to return lively flashes of white light while preserving deep green saturation through the body of the stone. The clarity description slightly included indicates the presence of minor natural inclusions, typical for tourmaline, which do not materially diminish its overall transparency or its appeal in a finished piece. Of particular importance to the informed buyer, this specimen has received no enhancement, confirming that the vivid green hue and the gem’s overall appearance are entirely natural, and its stated origin is Tanzania, a locality known for producing tourmalines with strong, pure greens and good crystal quality.

Under different lighting conditions this green tourmaline exhibits predictable and desirable optical behavior that will please both connoisseurs and everyday wearers. In bright natural daylight the stone displays its truest color, with intense grass to forest green tones that are evenly saturated across the table and crown, while the mixed brilliant facets create a lively play of brilliance and contrast that reads as clean, crisp flashes. Under warm incandescent lighting the color appears slightly warmer, which can lend the gem a richer, more luxuriant aspect, without compromising its clarity or brilliance. Under modern cool white LED lighting the stone retains excellent color integrity and exhibits strong facet contrast, which enhances perceived scintillation and makes the mixed brilliant cut particularly effective for jewelry that will be viewed in varied light sources. In low light or evening conditions the excellent polish aids light return so the gem maintains a subtle glow and noticeable flashes on movement, giving jewelry settings sparkle even when ambient light is limited. Backlighting or intense directional lighting will reveal internal reflections and the inclusion pattern, which in this specimen remains small enough to be non distracting, and which adds a degree of natural character valued by collectors who prefer untreated stones.

From the perspective of value and design the combination of intense, untreated color, careful cutting, and Tanzanian provenance makes this piece attractive to the educated buyer. Intense green tourmaline in the 0.3 carat range that is both transparent and unenhanced is less common than lower saturation material, and the cushion shape cut in a mixed brilliant fashion maximizes face up color while preserving brilliance, making it an excellent choice for a solitaire ring, a refined pendant, or as a focal stone in a bespoke design. The stone’s dimensions make it suitable for classic four prong settings that elevate the girdle to increase light entry, or for a low bezel setting that emphasizes durability while still allowing the table and crown to interact with ambient light. For metal pairing, white gold or platinum will emphasize the gem’s bright flashes and produce a cooler overall look, while yellow gold will warm the presentation and intensify the green’s richness. For collectors and investors, the lack of enhancement and the clear origin statement add provenance value, and The Natural Gemstone Company can assist with independent certification if desired, as well as recommendations for mounting and care to ensure the stone maintains its polish and color over time.

The Natural Gemstone Company stands behind the natural qualities of this tourmaline and can provide further information on sourcing, cut details, and recommended settings tailored to the buyer’s aesthetic and practical needs. Given the stone’s excellent polish and mixed brilliant cut, its optical performance will remain striking in daily wear, and its untreated origin from Tanzania offers a combination of beauty and geological authenticity that appeals to discerning buyers. Whether selected as a personal keepsake, a design centerpiece, or a collectible example of vivid green tourmaline, this 0.31 carat cushion provides a rare combination of intense color, transparent clarity, and thoughtful cutting that will perform beautifully across lighting environments, and The Natural Gemstone Company is available to guide you through certification, setting options, and care to ensure lasting satisfaction.
