5.86 Ct. Green Tourmaline from Ceylon (Sri Lanka)

This radiant shape green tourmaline weighs 5.86 carat, with precise dimensions of 20.50 by 6.64 by 4.71 mm, presenting a transparent body and a mixed brilliant cut that maximizes scintillation while preserving the stone balance. The gem carries a clarity grade of eye clean when evaluated at eye level, meaning no inclusions are visible to the unaided eye, and the excellent polish enhances light return across the pavilion and crown facets. Color assessment places the stone at a dark color intensity, which is prized by connoisseurs for its depth and saturation, allowing the green hue to read as rich and velvety under varied lighting. There has been no enhancement of any kind, the origin is Ceylon Sri Lanka, and these factors combined substantively increase value for an educated buyer who seeks natural material with strong provenance. At The Natural Gemstone Company we prioritize full disclosure, and this tourmaline is presented with transparent grading information and laboratory grade observation language that supports confident purchasing.

Under magnification the internal features of this tourmaline reveal the kind of natural fingerprint that makes each specimen unmistakable and collectible, even though the stone is eye clean. Fine needlelike inclusions and delicate hairline growth veils occur in orientations that follow the crystal habit, producing faint silk like alignment that can produce subtle internal scintillation and a softening of color zones when viewed from certain angles. Minute two phase and rarely occurring three phase inclusions, consisting of tiny liquid pockets with gas cavities and minute solid detritus, are consistent with authentic Sri Lankan pegmatitic tourmaline formation, and they act as natural certificates of origin and integrity. These inclusions are not flaws in the conventional sense, they are diagnostic features that confirm the gem has not been heat treated or glass filled, and they offer a microscopic landscape that gemologists and knowledgeable collectors value for verification and study. For the discerning buyer who values documented origin, natural condition, and a unique internal signature that ties the stone to Ceylon Sri Lanka, this 5.86 carat radiant tourmaline from The Natural Gemstone Company represents a rare combination of aesthetic presence, gemological authenticity, and enduring investment appeal.
