1.65 Ct. Tourmaline from Tanzania

This listing presents a single, transparent green tourmaline weighing 1.65 carat, cut into a precise trillion shape with dimensions 7.55 by 7.49 by 5.03 millimeters, originating from Tanzania, offered by The Natural Gemstone Company. The stone exhibits a vivid and intense green hue that reads consistently rich across the table and pavilion facets, while remaining saturated without appearing overly dark. The trillion cut creates a contemporary triangular silhouette, giving the gem a substantial visual face up area relative to its carat weight, and creating an energetic play of light within the stone. The gem is free of any treatments or enhancements, which preserves its natural character and makes it especially desirable to collectors and connoisseurs who prioritize untreated material.

From a gemological perspective this tourmaline rates highly across the traditional color clarity and cut criteria that educated buyers use to assess value and rarity. Color is the primary driver of value in tourmaline, and this piece shows intense color saturation combined with an attractive medium to deep tone that maximizes brilliance without losing vividness. Clarity is described as very very slightly included when evaluated at eye level, which indicates an eye clean appearance in everyday viewing, with only minute inclusions detectable under magnification. The excellent polish and well executed facet proportions contribute to strong luster and return of light, enhancing scintillation and the stone sensorial presence in a setting. For buyers who consider technical specifications important this gem also benefits from stable crystalline properties characteristic of chrome and verdelite type greens, and its resistance to wear is in line with tourmaline hardness near seven to seven and a half on the Mohs scale, making it suitable for rings as well as pendants and earrings with appropriate protective settings.

Ethical sourcing is a key consideration for conscious collectors and it is central to the provenance narrative of this specimen. The stone was sourced from Tanzania through supply chain channels that The Natural Gemstone Company maintains with a commitment to responsible procurement. This includes direct engagement with mining communities and downstream partners to encourage safe working conditions, fair remuneration, and environmental stewardship. The fact that the tourmaline is untreated enhances its ethical desirability, as no lab treatments were applied to modify color or clarity, reducing dependency on processing facilities and chemical inputs. For buyers who prioritize traceability, Tanzanian origins are significant because they allow for clearer mine to market narratives, and because artisanal to small scale mining operations in the region can be supported through conscientious purchasing that channels funds back to local economies and community initiatives.

In terms of practical considerations for design and collection management this 1.65 carat trillion green tourmaline lends itself to a range of settings that showcase its triangular geometry and vibrant color. Classic three prong settings align with the stone geometry and allow maximum light entry, while low bezel designs offer protection for the pointed corners for everyday wear. The gem is ideal as a striking center stone for bespoke pieces, or as a standout accent in curated collections where untreated, eye clean, and ethically sourced stones are valued. Care is straightforward and aligns with standard tourmaline practice, using warm soapy water and a soft brush, avoiding harsh chemicals and high heat, and storing separately to prevent abrasion from harder gems.
