5.07 Ct. Orangish Yellow Citrine from Brazil

This orangish yellow citrine, presented by The Natural Gemstone Company, is a 5.07 carat, round shape, transparent gem with exact dimensions of 11.06 by 10.99 by 7.85 millimeters. The stone is faceted in a mixed brilliant cut, with intense color intensity and a clarity grade described as very very slightly included at eye level. Origin is Brazil, and there has been no enhancement applied to alter color or clarity. The excellent polish across all facets is immediately evident in hand and in photography, providing clean facet junctions and a highly reflective crown plane. Face up, the gem reads a warm, saturated orangish yellow that remains consistent through moderate changes in viewing angle, which reflects the combined effect of material saturation and intentional facet design. These baseline characteristics define the gem for a technically minded buyer who requires precise measurements and verifiable provenance in addition to aesthetic appeal.

The mixed brilliant cut on this specimen is executed to reconcile two objectives, maximal light return and optimal color presentation. The crown employs brilliant style faceting to disperse light into multiple small flashes and to break up internal reflection into scintillation that is lively on movement. The pavilion is proportioned with modified facets to increase the effective path length of light through the body of the quartz, which deepens the perceived saturation of the orangish yellow hue without producing dark windowing. The table is sized to provide a balance between broad face up color and the contrast necessary for strong scintillation, while the crown angles have been calibrated to the refractive index typical of quartz, ensuring that the majority of incident light is redirected back through the crown rather than lost through the pavilion. The mixed approach yields a visual behavior where broad, warm color is maintained in static viewing, and controlled flashes of brilliance and contrast appear with motion, delivering both visual weight and dynamism.

Clarity and polish work together on this stone to preserve light performance and optical purity. The very very slightly included grade as evaluated at eye level indicates that any inclusions are minor in size and generally located away from the central table plane, which prevents significant scattering of light that could reduce contrast or dull the gem. The excellent polish minimizes micro abrasion that would otherwise diffuse specular reflections and soften facet edges, so facet junctions remain crisp and reflections remain well defined. In a material with a refractive index in the range typical for citrine, which provides modest dispersion and moderate brilliance, maintaining high polish is essential to achieving sharp, high contrast flashes. The cutter has optimized facet intersection quality and girdle symmetry to reduce light leakage at facet boundaries, and that attention to surface finish enhances perceived clarity and strengthens both brilliance and color saturation. The absence of enhancement preserves natural growth structure and ensures predictable aging and wear characteristics in set jewelry.

For bench setting and design considerations, this citrine performs well in both open and closed gallery mounting styles. The robust face up color and round outline make the stone suitable for a solitaire ring where the crown can be fully exposed to maximize light entry, and the slightly deeper profile indicated by the recorded depth dimension also supports secure bezel or semi bezel settings without compromising face up brilliance. The mixed brilliant design lends itself to designs that emphasize motion and fire, since the stone responds to changes in light with a pleasing mix of broad color and scintillating flashes. As supplied by The Natural Gemstone Company, the gem arrives with verified origin information and treatment disclosure, and we can provide additional angle specific images or custom facet diagrams on request to assist in setting design and appraisal. For collectors and jewelers who prioritize technical excellence in cutting, transparent natural origin, and a rich orangish yellow presence, this citrine represents a carefully executed balance of proportion, polish, and optical performance.
