7.70 Ct. Green Tourmaline from Ceylon (Sri Lanka)

This beautiful transparent 7.70 carat radiant shape green tourmaline measures 13.88 x 10.30 x 7.32 mm, and presents a vivid, intense color intensity that is rare for tourmaline at this scale, making it immediately eye catching for collectors and connoisseurs alike. The radiant cut maximizes brilliance and faceting symmetry, producing a lively play of light across the table and pavilion, and the excellent polish ensures crisp facet junctions and sustained sparkle under close scrutiny. Clarity is graded as included, evaluated at eye level, which means that while the stone is visually clean from a distance, it contains internal features that are visible to the naked eye on closer inspection. These inclusions are not flaws to conceal, they are unique identifiers, akin to a gemstone fingerprint, and they tell the story of the crystal growth environment, often appearing as fine needles, tiny crystals, or wispy liquid and gas inclusions, each pattern and orientation providing evidence of natural formation and geographic origin.

This tourmaline is untreated, with no enhancement, and its stated origin is Ceylon, Sri Lanka, a region known for producing finely colored gemstones with distinct internal characteristics, which adds provenance value for the discerning buyer. The absence of treatments preserves both the natural color and the integrity of the crystal, which is an important consideration for long term value and for those who prioritize natural, unaltered material. From a practical standpoint, tourmaline offers good durability for everyday jewelry, with a hardness that supports regular wear when set and cared for properly. For the educated buyer, the combination of weight, dimensions, radiant cut, intense green color, natural inclusions, no enhancement, excellent polish, and Ceylon origin creates a compelling profile, balancing aesthetic appeal and verifiable natural history. The Natural Gemstone Company is proud to present this specimen with detailed photographic and measurement documentation, and our team is available to discuss clarity photographs, inclusion mapping, and independent certification options to support informed purchase decisions.
