9.90 Ct. Yellowish Orange Citrine from Ceylon (Sri Lanka)

This offering from The Natural Gemstone Company is a beautifully executed marquise shaped citrine, weighing 9.90 carats, with precise dimensions of 18.81 x 11.06 x 8.69 mm. The gemstone is transparent, exhibiting an intense yellowish orange hue that reads as both warm and vibrant under natural and artificial light. The cutting style is faceted, using a mixed brilliant approach that emphasizes light return and color saturation. Clarity is graded as very very slightly included when evaluated at eye level, indicating exceptional visual cleanliness with only minute inclusions detectable under magnification. The piece has undergone standard heat treatment to enhance and stabilize its tone, and originates from Ceylon Sri Lanka, a region renowned for producing gemstones with lively coloration and fine crystalline quality. An excellent polish across all facet planes ensures crisp reflections and a bright surface luster that immediately communicates quality to an informed viewer.

The mixed brilliant cut applied to this marquise balances the opposing demands of brilliance and color. On the crown, carefully proportioned brilliant style facets capture and refract incident light, producing scintillation and lively white flashes. The pavilion incorporates an arrangement that controls light leakage and deepens the apparent color by directing light back through the body of the stone. The marquise outline, with its elongated symmetry and gently curved terminations, amplifies perceived size and creates a series of contrast zones along the length of the stone. Proportions have been managed to reduce undesirable windowing effects and to minimize the central bow tie phenomenon common to elongated cuts, while preserving strong edge to edge light performance. Facet junctions are precisely aligned, facet angles are cut to optimize return at typical viewing distances, and the overall symmetry contributes to an even play of light and color across the surface.

Color and clarity work together in this specimen to produce an immediate visual impact. The intense color intensity speaks to a high level of uniform saturation, with yellowish orange tones distributed evenly rather than concentrated in localized zones. Heat treatment has been applied conservatively, targeting enhancement of the warm hues without creating unstable or artificial looking tones. The very very slightly included clarity grade at eye level means that the gem reads as effectively eye clean to most observers, and inclusions, when present, are small and well positioned so as not to interfere with brilliance. The excellent polish creates sharp facet planes and precise facet edges, maximizing specular reflection and contributing to vivid contrast between bright flashes and darker facet windows. From a gemological perspective the material exhibits sound crystal integrity and a stability that makes it suitable for a wide range of settings.

This citrine is crafted to be an enduring source of admiration, its natural beauty maintaining and in many ways increasing in appeal over the years. Quartz family hardness of seven on the Mohs scale imparts practical durability, and when set with attention to protective metalwork the stone will resist ordinary wear while retaining its polish. The stabilized color resulting from controlled heat treatment is not prone to rapid fading, and the excellent initial polish provides a surface condition that tolerates routine cleaning without significant loss of luster. For care we recommend periodic professional inspection to ensure settings remain secure, gentle cleaning with warm water and mild detergent, and avoidance of harsh chemicals or prolonged exposure to extreme heat. Whether mounted as a solitaire that showcases the marquise silhouette, incorporated into a halo design that amplifies its face up presence, or set into a bespoke piece that takes advantage of its elongated proportions, this citrine will continue to captivate.
