16.13 Ct. Orange Cabochon Citrine from Brazil

This exceptional transparent orange citrine from The Natural Gemstone Company weighs 16.13 carats and is shaped as an elongated oval cabochon with precise dimensions of 21.09 x 13.97 x 8.57 mm. The cutting style is a classic domed cabochon, executed with strict attention to axial symmetry and edge rounding to produce a clean oval outline and a continuous silhouette from girdle to dome. The length to width ratio of 1.51 yields an elegant, elongating profile suitable for rings or pendants, while the substantial dome height contributes to optical depth without compromising wearability. Originating from Brazil, and stabilized by controlled heat treatment to enhance hue uniformity, this citrine presents a stable, intense orange color intensity that reads consistently across transmitted and reflected light.

Clarity is assessed as very very slightly included, evaluated at eye level, a grade indicating that inclusions are imperceptible without magnification and do not interrupt full transparency. This near flawless internal character allows unobstructed light transmission, producing a vivid, saturated face up appearance and an even color field across the oval surface. The excellent polish is evident in the mirror like finish of the dome, where surface micro roughness has been removed to deliver high specular reflection and silky luster. Because the cutter prioritized an even finish on both the crown and the girdle edge, light enters the dome, diffuses softly within the body of the stone, and exits with minimal scattering, giving a clean, crystalline glow that emphasizes the citrine s intrinsic color rather than surface artifacts.

The gem s faultless optical performance enhances its beauty from every angle, a quality that is especially relevant for cabochon geometry where curvature governs visual effects. The 8.57 mm dome height equals approximately 40.6 percent of the stone s length and approximately 61.3 percent of its width, a proportion that creates a pronounced window of color at the crown center while maintaining graceful transitions at the sides. From oblique viewpoints the high dome produces a luminous pooling effect, concentrating the intense orange toward the center and generating a soft halo toward the periphery. When backlit the transparency yields a clear internal field with only the slightest, microscopically confined inclusions, reinforcing an impression of purity and depth. The absence of structural cleavage planes or feathery fissures improves both aesthetic continuity and mechanical integrity, ensuring the gem resists common stressors in daily wear when set with appropriate protective mounting.

The craftsmanship technique applied here reflects precision cabochon cutting practice, including careful preforming to maximize weight retention, calibrated dome curvature to control color saturation, and final lapidary polishing using progressively finer abrasives to achieve an excellent polish grade. The heat treatment used is a standard, stable enhancement that intensifies the natural orange without introducing artificial zoning or surface residues, and the Brazilian origin is consistent with the material s crystalline habit and color chemistry. For setting, the piece performs exceptionally well in closed bezel mounts that protect the girdle while showcasing the dome, and in open backed designs where light can transmit to enhance brilliance. Collectors and designers seeking a technical balance of size, proportion, and near flawless clarity will find this 16.13 carat oval cabochon citrine a superior choice from The Natural Gemstone Company, a gemstone that demonstrates how meticulous cutting and finishing elevate inherent material quality into a jewel that reads beautifully from every viewing angle.
