6.03 Ct. Greenish Blue Tourmaline from Mozambique

This emerald cut tourmaline presents a rare combination of weight, dimensions, and hue, a feature that distinguishes it from the more common examples of this species. At 6.03 carats, and measuring 14.26 x 8.34 x 5.73 millimeters, this transparent specimen sits well above the typical size range for greenish blue tourmaline crystals that maintain high clarity. The color is a refined greenish blue with a dark intensity, a tone that is less frequently encountered than the more common pastel greens or intense blues. The step facet architecture of the emerald cut emphasizes its internal cleanliness, and the clarity grade is eye clean when evaluated at eye level, enabling an unobstructed window to the gem color. The polish is excellent, providing crisp facet junctions and a smooth surface that enhances light return along the pavilion and table, and the piece has been heat treated, a standard enhancement that stabilizes and intensifies the color. Origin is Mozambique, a source known for producing tourmaline with appealing saturation and durability, and this provenance further supports its desirability among collectors and designers.

For the client seeking a statement center stone with both rarity and practical versatility, this tourmaline offers substantial advantages. Its substantial carat weight and elongated emerald cut silhouette suit bespoke ring settings, pendants, and high end cocktail pieces, while the dark greenish blue hue translates with sophistication under varied lighting. Compared to similar tourmalines, stones of this size and of this specific color depth are uncommon, making it particularly attractive for connoisseurs and those specifying one of a kind pieces. The Natural Gemstone Company provides full descriptive information, additional imaging, and condition notes on request, and can advise on setting styles that protect and showcase the step cut geometry. Care requirements are modest, similar to other gem quality tourmalines, and recommendations for secure mounting and professional cleaning can be provided. This example represents a notable opportunity to acquire a sizeable, eye clean, emerald cut greenish blue tourmaline with excellent polish and documented origin.
