1.31 Ct. Cabochon Tourmaline from Mozambique

This offering from The Natural Gemstone Company is a transparent white tourmaline, cushion shape, weighing 1.31 carat, with precise measurements of 6.89 by 6.84 by 4.29 millimeters. The gem has been fashioned in a sugar loaf style which yields a gently domed profile with facet lines that emphasize soft light return rather than aggressive brilliance. Color intensity is colorless, presenting a neutral and near crystalline appearance that allows settings and surrounding metals to remain the visual focus. The surface is finished to an excellent polish, resulting in a smooth, reflective plane that enhances the stone clarity and the perception of depth. There has been no enhancement applied to this specimen, confirming that color and clarity are natural characteristics preserved from the mine to the finished stone. The material is sourced from Mozambique, a locality noted for producing well formed tourmalines with clean, achromatic examples in recent years.

Clarity is graded as very slightly included evaluated at eye level, which in this instance corresponds to a small dark crystal inclusion positioned near the pavilion and a limited number of fine internal growth features visible under close inspection. These internal characteristics are stable and do not compromise the structural integrity of the stone. They also contribute to the gemological identity and natural provenance of the piece. The sugar loaf cushion cut disperses light across curved surfaces, creating a soft luminous effect that is more about subtlety of tone than high dispersion or fire. Given the 4.29 millimeter depth, proportions are well balanced for this weight class and shape, offering a pleasing table size and an even distribution of light. The combination of transparency, minimal inclusion, and superior polish produces an object that reads as clean and versatile in multiple mounting styles.

From a practical standpoint the stone’s hardness and durability are consistent with the tourmaline group, offering reliable performance in jewelry when appropriate care is observed. Preferred mounting options include bezel settings that protect the domed profile and pavilion area, or four to six prong settings that secure the gem while allowing light to enter the table. Given the central placement of the more noticeable inclusion, orienting the pavilion toward the metal back of a setting can minimize visual impact when desired. Cleaning is best accomplished with warm soapy water and a soft brush, avoiding harsh chemicals and high heat exposure, and careful handling is recommended to prevent knocks against harder surfaces. For buyers seeking documentation a standard gemological report that confirms weight, dimensions, cut description, clarity assessment noted as very slightly included evaluated at eye level, colorless intensity, absence of enhancement, and Mozambique origin can be provided. This description is intended to present the factual attributes of the stone to assist in design and appraisal decisions.
