16.95 Ct. Yellowish Orange Citrine from Brazil

This listing describes one transparent oval citrine of substantial size, presented by The Natural Gemstone Company. The gemstone weighs 16.95 carats, and measures 19.08 by 14.65 by 10.82 millimeters, dimensions that yield a commanding face up presence for both ornamental and bespoke jewelry applications. The cutting style is faceted with a mixed brilliant cut, a design that combines step and brilliant facet arrangements to balance table size, depth, and internal light performance. The color is best described as yellowish orange with intense color intensity, and the finish is an excellent polish that produces a clean, lustrous surface. Clarity is graded very very slightly included at eye level, indicating minimal internal characteristics that do not materially detract from the gem when examined without magnification. The stone has been heat treated, a common and stable enhancement for citrine, and originates from Brazil, a source noted for producing well colored and clean examples of this species.

Optical and physical characteristics combine in this stone to produce a strong, appealing visual performance. Transparency is high, allowing light to penetrate and return through the crown facets with minimal diffusion, which preserves saturation and face up color. The mixed brilliant cut leverages a broad table and a generous depth, yielding both broad flashes and lively scintillation as it moves. The excellent polish ensures facet junctions and planes behave as intended, providing crisp facet reflection and a pronounced mirror like sheen on the crown. Given the very very slightly included clarity, small natural features remain present on close inspection, adding to the natural provenance without compromising brilliance or overall appearance. Dispersion in citrine is modest by gemological standards, so the observable fire is understated, but the combination of transparency, facet design, and polish produces vivid brilliance and attractive internal light play.

Lighting conditions influence both the apparent hue and the manner in which the stone delivers brilliance, and this citrine performs reliably across a range of illumination environments. In bright daylight, including north light and open shade, the yellowish orange color reads as clean and intense, with even saturation across the face of the gem, and the mixed brilliant faceting produces clear, broad flashes of light and consistent scintillation. Under warm incandescent light, the stone takes on a deeper, more orange leaning tone, and the warmth of the illumination enhances the gem like warmth and richness of the color, producing a compelling, glowing appearance. Under modern cool white LED light, the color shifts slightly toward the brighter yellow spectrum, and the crispness of LED lighting accentuates facet contrast, making scintillation appear slightly more staccato and pronounced. In lower light or candlelight the gem presents a soft, warm glow, with lower overall flash but a pleasing, saturated face up color that reads as warm and inviting. Direct focused lighting, such as a gallery spotlight or jewelry display lamp, reveals the clearest evidence of the cut working as intended, showing pronounced internal reflections and localized flashes, while the modest dispersion of citrine means spectral fire is present but subtle, contributing to depth and vitality rather than distracting color flashes.

Practical considerations for use and care follow from the character of the stone. At 16.95 carats and with the given dimensions, this citrine is suitable for a statement pendant, a prominent ring setting with secure prongs and protective shoulders, or a devoted centerpiece in a brooch or collar necklace. The mixed brilliant cut provides a balance of face up size and light performance, and the very very slightly included clarity means the stone presents cleanly in a prong or bezel setting, although a setting that protects the girdle and pavilion is recommended for daily wear. Heat treatment is stable under normal conditions, and routine cleaning with warm soapy water and a soft brush restores surface luster, while prolonged exposure to harsh chemicals and extreme heat should be avoided to preserve the integrity of the polish and color. This example, sourced from Brazil and offered with the descriptive details above, represents a substantial, well finished citrine that demonstrates reliable performance across lighting environments, and embodies the straightforward quality and provenance information we provide at The Natural Gemstone Company.
