15.73 Ct. Purplish Pink Kunzite from Madagascar

This listing describes a single, transparent purplish pink kunzite weighing 15.73 carats, presented in a cushion shape, with precise dimensions of 16.58 x 13.46 x 9.15 mm, prepared by skilled lapidary work. The cutting style is faceted, executed as a mixed brilliant cut, combining pavilion facets that enhance brilliance with a crown arrangement that maximizes color and windowing control. Clarity is graded as eye clean, evaluated at eye level, indicating the absence of inclusions visible without magnification, and the surface finish is characterized by an excellent polish. The color is a medium intensity purplish pink, offering a balanced saturation that reads vividly in a variety of lighting conditions without appearing overly dark. The material has been heat treated to enhance and stabilize the hue, consistent with common, accepted enhancement practices for this variety, and the piece originates from Madagascar, a recognized source of fine gem quality kunzite.

Optical and material attributes of this kunzite are important for assessment and design considerations, the stone is transparent with a clean window through the table, and the mixed brilliant faceting promotes lively return of light while shaping the apparent face color. Pleochroism is a known characteristic of kunzite, and this stone displays subtle directional color variations when viewed from different angles, which can add depth and visual interest in finished jewelry. The excellent polish supports optimal light performance and tactile smoothness, contributing to a refined appearance when set. The cushion outline is a versatile choice that can be used in a range of mounting styles, from classic solitaire settings to more elaborate designs that emphasize the stone as the focal point. Because the clarity is eye clean, the faceting pattern can be appreciated without distraction from internal features, supporting both aesthetic quality and valuation.

On the Mohs scale of mineral hardness, kunzite registers at approximately 6.5 to 7, this places it below traditionally durable stones such as sapphire at 9 and topaz at 8, and at or slightly below common quartz at 7. The hardness indicates reasonable resistance to abrasion during normal wear, however this should be considered in the context of the mineral’s crystallographic properties, kunzite is a member of the spodumene group and exhibits distinct cleavage in two directions, this pronounced cleavage makes it more susceptible to fracture or splitting if struck or subjected to lateral pressure. For practical durability and long term care, settings that provide protective bezels or deep prongs, and designs that shield the girdle and edges are recommended, because even with a surface that resists scratches to a degree, impact or sharp blows can propagate along cleavage planes more readily than in isotropic or tougher gem materials.

Care and handling guidance is provided to preserve both color and structural integrity, avoid exposure to prolonged high heat or intense sunlight for extended periods because kunzite can be sensitive to light and may gradually fade if left under direct sunlight for very long durations, the heat treated enhancement applied to this stone is stable under normal wearing conditions, however extreme heat can risk alteration. Ultrasonic and steam cleaning are not recommended without prior consultation with a qualified gemologist, gentle cleaning with warm soapy water and a soft brush is the preferred method. For settings, choose designs that minimize exposure of the stone’s edges while allowing light to interact with the crown, this approach maintains aesthetic appeal while mitigating the risk associated with cleavage. The Natural Gemstone Company stands behind the accuracy of the description and the provenance information, and can provide additional documentation regarding treatment and origin upon request, the provided details assist in responsible selection for collectors, designers, and end users who prioritize a balance of visual quality and practical considerations in handling and wearing.
