5.03 Ct. Yellow Citrine from Brazil

This listing presents a single, transparent 5.03 carat round yellow citrine, precisely measured at 11.10 x 11.24 x 8.16 mm, offered by The Natural Gemstone Company. The cutting style is faceted, executed as a mixed brilliant cut which combines a brilliant crown with a step style pavilion to balance scintillation with color depth. The gem displays an intense color intensity, a clarity grade of very slightly included when evaluated at eye level, and an excellent polish across all facet planes. Enhancement is by heat treatment, a controlled and stable industry standard used to achieve and lock in the warm golden yellow hue, and the stated origin is Brazil, a classical source for high quality quartz varieties. Optically, citrine is a quartz species with a refractive index in the range of approximately 1.544 to 1.553, a modest birefringence of about 0.009, and low dispersion near 0.013, properties that contribute to a consistent, lively face up appearance and clean, focused brilliance when well cut.

From a lapidary and craftsmanship perspective the mixed brilliant cut has been employed here to reconcile two competing objectives, maximum face up spread and optimal color saturation. The cutter preserved a robust depth of approximately seventy three percent, by averaging the two diameter measurements to determine a proportional depth, which intentionally enhances the perceived intensity of the yellow without sacrificing table scintillation. The facet architecture follows a conventional mixed brilliant schema, with a crown of well proportioned star and kite facets feeding light to a pavilion comprised of concentric step facets, delivering strong return and dispersion while concentrating color in the table and upper pavilion. The execution shows very precise facet junctions and symmetry, and the excellent polish yields mirror like facet surfaces that minimize light leakage and maximize lively reflections. The result is a gem that displays both the lively flash associated with brilliant faceting and the saturated, stable hue achieved by the deeper pavilion planes typical of mixed styles.

In the current market a round citrine at just over five carats with this combination of attributes is notably uncommon. Large citrines are available, but many examples at this scale exhibit washed or brownish tones, increased inclusion levels, or are cut with proportions that favor weight retention over optics. What sets this specimen apart is the convergence of intense, evenly distributed yellow color, high transparency with only very slight inclusions visible to the unaided eye, and a cutting design that purposefully trades modest spread for concentrated chroma and lively brilliance. The heat treatment applied to this stone is a conventional enhancement in quartz that yields a stable color result, and in this example the treatment has been executed without compromising clarity or cutting integrity. For designers and collectors seeking a statement center stone, the dimensions and profile lend themselves to a variety of settings, including open gallery rings and pendant bezels that allow light to interact with the pavilion, or precision prong settings that showcase table presence and color saturation. In summary, this 5.03 carat Brazilian citrine offered by The Natural Gemstone Company represents a rare combination of size, transparent clarity, intense yellow coloration, and high quality cutting, making it an exceptional option for a premium bespoke piece or a discerning collection.
