1.89 Ct. Green Tourmaline from Ceylon (Sri Lanka)

This 1.89 carat green tourmaline, cut to a radiant shape, measures 7.51 x 6.38 x 4.23 millimeters, and is presented by The Natural Gemstone Company. The gem exhibits an intense color intensity that sits firmly in the rich green range, with hue saturation that produces deep, velvety tones without veering toward brown or gray. Clarity is graded as slightly included at eye level, with small internal characteristics that do not affect the structural integrity of the stone, and that contribute to its natural origin and character. The piece is untreated, with no enhancement, allowing collectors and designers to work with a stone whose optical and chemical properties are wholly natural, and whose visual appeal is the result of precise cutting and inherent material quality.

The radiant cut employed here is executed to balance step and brilliant faceting, creating a pavilion that returns light through both broad flashes and scintillating facets. The rectangular outline with trimmed corners provides a modern, architectural profile, while the faceting schema maximizes face up spread for its carat weight. Excellent polish is evident across table, crown, and pavilion facets, producing crisp facet junctions and controlled light leakage. This polish, together with careful orientation of the stone to its optic axis, reduces windowing and accentuates pleochroic tendencies common to tourmaline, producing subtle shifts between deeper forest green and lighter leaf green as the stone moves, a desirable attribute for connoisseurs who value dynamic color behavior.

Origin is documented as Ceylon, Sri Lanka, a source known for producing tourmalines with saturated, clean colors and stable crystal growth conditions. The Natural Gemstone Company sources this gem through established supply relationships with miners and cutters in Sri Lanka, following transparent chain of custody practices. We prioritize traceability, and where possible, independent verification of origin is facilitated by local documentation and consistent supplier records. Ethical sourcing protocols include direct purchasing agreements that aim to secure fair compensation for miners, funding for safe working conditions, and support for local cutting workshops that preserve regional lapidary skills. The absence of enhancement reduces further processing steps, minimizing the environmental footprint, and preserving the stone in its naturally occurring state.

For the conscious collector or the designer focused on longevity and responsible procurement, this tourmaline integrates technical excellence with ethical consideration. Its dimensions and radiant geometry make it well suited for bezel or prong settings that protect the trimmed corners, and the slightly included clarity grade allows for confident daily wear when set with appropriate security. The intense color intensity and excellent polish make it a focal point in bespoke jewelry, while the lack of enhancement preserves resale value and simplifies future appraisal. The Natural Gemstone Company provides provenance documentation and can coordinate independent gemological assessment upon request, supporting transparent acquisition and stewardship. For those assembling a collection with an emphasis on natural, well sourced gemstones that demonstrate both precise craftsmanship and conscientious sourcing, this Ceylon green radiant tourmaline represents a technically refined and ethically considered choice.
