0.44 Ct. Brownish Red Tourmaline from Mozambique

This listing presents a single, transparent 0.44 carat oval tourmaline originating from Mozambique, supplied by The Natural Gemstone Company. The gem measures 5.86 x 3.92 x 3.20 mm, and it is fashioned in an oval outline with a mixed brilliant cut. The cut combines a faceted crown with pavilion facets arranged to balance color and light return, producing a pleasing table and overall symmetry. The stone exhibits intense color saturation described as brownish red, with an excellent polish that enhances surface reflectivity. Clarity is graded slightly included at eye level, indicating small internal features that are visible under close observation but do not significantly obstruct light transmission. There has been no enhancement applied to this material, the stone is offered in its natural state, and its Mozambican origin is consistent with known sources for richly colored tourmaline varieties.

Optically this tourmaline demonstrates the typical vitreous luster of the species, with a bright, glass like surface sheen that responds well to directional light. The mixed brilliant cut supports lively facet contrast and controlled scintillation, while the gem still retains the depth and body of its intense brownish red hue. Tourmaline is known for pleochroism, and this specimen displays subtle directional color variation when rotated under a light source, revealing slightly different tones depending on the viewing axis. The slightly included clarity grade permits excellent transparency, allowing light to pass through the stone while internal characteristics offer visual depth and character. The excellent polish ensures that surface reflections are crisp and mirror like, enhancing perceived sharpness of facet junctions and aiding the gem in returning light to the viewer rather than scattering it at the surface.

When compared to other gemstones within the same general category of colored gemstones, this tourmaline exhibits a distinctive balance between color depth and reflective behavior. Tourmaline generally has a refractive index range in the mid 1.62 to 1.64 area, which yields strong surface brilliance but moderates the intensity of internal sparkle compared with higher refractive index stones. By contrast, garnets and corundums, with higher refractive indices, often present greater brilliance and more intense light return for equivalent cuts. Spinel, with an intermediate refractive index, can appear more lively in terms of sparkle than tourmaline of similar size. Tourmaline compensates for more moderate dispersion and fire through its rich coloration and pleochroism, which can create a dynamic visual effect as the stone is moved under light. In practical terms, this brownish red tourmaline will show less spectral flash or fire than a diamond or high dispersion gem, but it will offer a deeper, more saturated color presence and directional color play that many collectors and designers value for warm tone settings.

For practical use and selection, this 0.44 carat oval tourmaline is well suited to settings that emphasize color and form rather than maximum scintillation. The mixed brilliant cut and excellent polish make it appropriate for close set rings, pendants, or accent pieces where the stone will be viewed from multiple angles, allowing its pleochroic character to be appreciated. The slightly included clarity grade should be considered when determining setting style, as prong orientation and mounting height can influence how inclusions are presented or concealed. The absence of enhancement is notable from a preservation and valuation perspective, as untreated material from Mozambique is sought after for its natural color expression. The Natural Gemstone Company provides this specimen with transparent details regarding cut, clarity, and origin, supporting informed decisions by jewelers, collectors, and connoisseurs who prioritize intrinsic gem properties over artificial treatments. Care instructions align with typical guidance for tourmaline, recommending protection from hard knocks and ultrasonic cleaning only after consultation, to preserve the polished finish and natural integrity of the stone.
