16.44 Ct. Smoky Smokey Quartz from South Africa

This 16.44 carat cushion shape smoky quartz from The Natural Gemstone Company presents as a rare large size with exceptional gemological attributes. The dimensions measure 16.92 x 14.01 x 9.12 mm, yielding an approximate depth ratio of 59 percent when using the mean of length and width, a proportion that complements the mixed brilliant faceting to deliver an even balance between depth driven body color and face up brilliance. The mixed brilliant cut combines a faceted brilliant crown with a modified step pavilion, creating a dynamic interplay of broad flashes and fine scintillation. The clarity is graded as very slightly included at eye level, meaning inclusions are minimal and do not detract from the gem face up appearance, while the polish is excellent, indicating well executed facet junctions and mirror like facet planes. The tone is faint smoky with transparent body color, and the stone is free of any enhancements, originating from South Africa, a locality noted for producing clean, large quartz crystals suitable for precision cutting.

From a craftsmanship perspective this piece demonstrates meticulous cutter intention to maximize carat weight retention while optimizing optical performance. The cushion outline with softened corners and substantial table area allows a significant face up presence for the 16.44 carat weight, making the gem read larger on the finger or in a pendant than many similarly weighted rounds. The mixed brilliant faceting schema has been proportioned to generate lively brilliance from table to girdle, while the pavilion angles and crown height have been calibrated to prevent excessive windowing and to preserve the faint smoky tone uniformly through the stone. The absence of enhancement enhances its premium classification, as the natural color and clarity are intrinsic. This smoky quartz suits collectors and high end designers seeking a centerpiece stone, and it adapts well to prong or low bezel settings that protect the cushion corners while showcasing the significant carat presence. The Natural Gemstone Company stands behind this specimen as a premium, untreated gemstone with notable size, refined cut, and professional finishing, an excellent choice for a signature ring or a museum quality collection where carat weight and natural provenance are paramount.
