10.66 Ct. Cabochon Tourmaline from Mozambique

This piece is a transparent 10.66 carat cushion shaped tourmaline cut in a sugar loaf style, presenting dimensions of 12.18 by 12.12 by 7.86 millimeters, originating from Mozambique. The bodycolor is purplish pink with a vivid color intensity, and the stone is untreated, with no enhancement. Clarity is graded as very slightly included evaluated at eye level, a designation that reflects minimal internal features that do not detract from the optical performance when viewed without magnification. The combination of substantial size, fine transparency, and vivid saturation produces strong light return and a deep, velvety color depth that reads as rich purplish pink across multiple lighting conditions, while thin edge areas exhibit subtle variations in tone consistent with tourmaline pleochroism.

The sugar loaf cut on this cushion outline has been executed to emphasize depth and internal luminosity rather than brilliance in the classical faceted sense. The cutter shaped a high domed crown that flows into broad, planar facets converging toward a central apex on the crown, while the pavilion facets are arranged to direct light back through the crown, creating a concentrated visual window into the gem body. Facet junctions are sharp and well aligned, facet planes meet without noticeable overpolish or nicks, and the polish grade is excellent, producing a surface luster that maximizes both specular highlights and saturated core color. The cutter preserved material weight deliberately, leaving generous pavilion depth to maintain color saturation, an approach that favours even tone and dramatic face up color in a single stone of this size. The result is an object with architectural geometry, where facet orientation and apex placement create controlled flash points and internal reflections that emphasize the purplish component of the hue, while minor internal features are positioned and oriented so as not to generate distracting windowing or dead areas.

From a gemological and practical design perspective this tourmaline offers several advantages for high end applications. The carat weight and cushion dimensions make it suitable as a significant center stone for statement rings, pendants, or bespoke cocktail pieces, and the sugar loaf cut lends itself to protective settings such as low profile bezels or secure rail settings that preserve the domed crown while reducing exposure to knocks. Tourmaline hardness falls between 7 and 7.5 on the Mohs scale, which provides everyday wearability with normal care, and the absence of enhancements increases its long term value and collectibility, particularly with documented provenance from Mozambique. Color uniformity across the table and through the heart of the stone ensures reliable performance under different light sources, and the vivid intensity offers strong visual presence even when set in warm or cool metal tones. At The Natural Gemstone Company we subject each specimen to rigorous visual and instrumental inspection, and this piece arrives with condition notes that verify the sugar loaf cutting technique, the excellent polish, the stated dimensions and carat weight, the clarity observation of very slightly included evaluated at eye level, and the absence of any laboratory detectable treatments. For clients seeking a natural, boldly colored tourmaline with considered cutting decisions that prioritize weight retention, color saturation and refined surface finishing, this Mozambique purplish pink sugar loaf cushion represents a technically accomplished and visually compelling option.
