9.19 Ct. Cabochon Tourmaline from Mozambique

This listing describes a single, transparent red tourmaline weighing 9.19 carats, presented in a cushion silhouette and finished in a sugar loaf style, with overall dimensions of 11.34 by 11.28 by 7.80 millimeters. The stone exhibits vivid color intensity, an excellent polish, and a clarity grade of very slightly included, evaluated at eye level. No enhancement has been applied, and the material is documented as originating from Mozambique. The Natural Gemstone Company is pleased to offer this specimen as an example of high quality natural tourmaline in a distinctive cut that emphasizes depth of color and visual presence. Photographs supplied show the deep saturated tone and high degree of light return from the polished dome and subtly faceted crown area.

The sugar loaf execution here is a high domed cushion with controlled faceting on the crown that works with the rounded pavilion to create broad flash and a deep, even color window. This cut is intentionally volumetric, sacrificing some table brilliance in favor of depth and color saturation, which is ideal for red tourmalines where richness of hue is the primary aesthetic objective. Given the measurements the depth to average diameter ratio is approximately sixty nine percent, which aligns with the sugar loaf intent to retain weight while producing a visually substantial gemstone. Symmetry between the length and width is effectively square, measured at eleven point three four by eleven point two eight millimeters, and the overall outline is well balanced, which aids in even color distribution when set in jewelry.

Color and clarity are the defining technical aspects for this tourmaline, and in this specimen both are notable. The hue presents as a pure, strong red with a slight tendency toward a cooler, slightly purplish nuance under certain lighting conditions, a characteristic commonly encountered in manganese rich tourmalines from Mozambique. The vivid intensity indicates strong saturation with a medium dark tone that preserves internal transparency and avoids the appearance of blackout in typical jewelry lighting. Clarity is graded as very slightly included at eye level, and the inclusions present are minor internal features that do not interrupt the overall transparency or brilliance of the gem. These small inclusions are consistent with natural provenance and do not detract from the stone structurally, nor do they interfere with polish quality or faceting crispness.

From a practical and technical perspective this nine point one nine carat sugar loaf tourmaline is well suited to secure, protective mountings that respect its domed profile and preserved weight. Because the cut emphasizes depth and internal color rather than facet sparkle, settings that present the dome, such as bezel or low crown prong work, will best showcase the stone and protect its polished surface. Tourmaline hardness is approximately seven to seven point five on the Mohs scale, offering good daily wearability with normal care, but it should be protected from sharp knocks, extreme heat, and harsh chemicals to maintain polish and color. For buyers focused on provenance and integrity, this piece carries no indications of heating or other enhancement, and its Mozambique origin aligns with known deposit chemistry that produces saturated red stones.
