16.88 Ct. Brown Smoky Quartz from Brazil

The Natural Gemstone Company presents a transparent 16.88 carat marquise shape brown smoky quartz, precisely cut to dimensions of 25.21 x 15.03 x 10.19 mm. The gemstone is faceted with a mixed brilliant cut, combining pavilion and crown facet arrangements to maximize light return and scintillation. Evaluated at eye level, the clarity is graded eye clean, indicating an absence of inclusions visible to the naked eye, while the color displays an intense brown saturation that reads as warm and evenly distributed across the stone. The polish is excellent, producing smooth facet junctions and a high degree of surface luster. This specimen originates from Brazil, and it bears no enhancements, presenting a natural color and structure for clients seeking unaltered material.

From a durability perspective, this smoky quartz is well suited to daily wear when set appropriately. Quartz has a Mohs hardness of 7, providing good resistance to abrasion and surface scratching under normal use, while lacking a true cleavage plane, which reduces the likelihood of clean separations under stress. The marquise outline, with its tapered pointed terminations, does require attention to edge security, because acute points are more susceptible to chipping if subjected to direct impact. The mixed brilliant cut and excellent polish contribute to the stone sustaining its visual performance over time, as well cut facets and smooth surfaces are less likely to trap dirt and show wear. For ring applications that will be exposed to frequent contact, secure settings such as a full bezel or prong arrangements that incorporate protective shoulders or point guards will enhance longevity, while pendant and earring mounts offer inherently lower impact risk.

Care and handling recommendations are straightforward, emphasizing routine measures that preserve appearance and structural integrity. Cleaning in warm, soapy water with a soft brush is effective for removing accumulated oils and dirt, followed by careful rinsing and drying with a soft cloth. Avoid prolonged exposure to harsh chemicals and active chlorine, as these environments can degrade accompanying metalwork and surface finishes, and avoid sudden thermal shock from rapid temperature changes. Ultrasonic and steam cleaning can be acceptable for intact quartz without fractures, however professional inspection is advisable prior to such treatments, particularly for stones in vintage or tension settings. Store the gemstone separately from harder gems to prevent incidental scratching, and inspect mountings periodically to ensure prongs and settings remain secure.
