2.98 Ct. Bluish Green Tourmaline from Madagascar

This 2.98 carat transparent bluish green tourmaline, presented in an asscher octagon shape with dimensions 8.76 by 8.44 by 5.66 millimeters, exemplifies meticulous lapidary control and is a superb technical specimen for the advanced collector. The cutting style is faceted, executed as a classic asscher cut, employing concentric step facets on the crown and pavilion that produce precise light return and a hall of mirrors effect characteristic of fine step cuts. The asscher geometry with truncated corners emphasizes symmetry, reveals sharp facet junctions, and creates a central window that showcases the stone color in even planes. Clarity is graded eye clean at eye level, indicating the absence of inclusions that would interfere with visual performance under normal viewing, and the excellent polish ensures maximum luster on all facet planes. Color is a medium intensity bluish green, balanced between green saturation and blue undertones, and the stone exhibits the gentle pleochroic tendencies expected in tourmaline, offering slightly varying blue green tones when rotated under directional lighting. The gem has been heat treated, a stable and commonly accepted enhancement for color optimization, and originates from Madagascar, a source known for well saturated tourmalines with fine crystal quality. Refractive properties and optical symmetry align with quality tourmaline material, and the depth of 5.66 millimeters yields a well proportioned depth to average dimension ratio, maintaining weight retention while optimizing face up appearance.

As a curated acquisition from The Natural Gemstone Company, this asscher octagon tourmaline is the ideal addition to a high end gemstone collection, offering technical attributes that appeal to connoisseurs who value cut architecture and optical precision. Its combination of asscher step faceting, eye clean clarity, medium color intensity, and excellent polish makes it especially suitable for bezel and gallery settings that preserve geometric lines, or for a precision mount that highlights the step facets and central window. The measured dimensions and consistent facet finish facilitate accurate documentation for certificates and valuations, and the heat treated nature and Madagascar provenance are transparent data points for provenance records. For collectors seeking a balanced specimen that performs under loupe inspection and under exhibition lighting, this tourmaline provides both the technical integrity and aesthetic restraint expected in a museum quality cabinet or private high end collection, and it stands as a demonstration of the careful craftsmanship and gemological standards upheld by The Natural Gemstone Company.
