10.33 Ct. Orange Citrine from Brazil

This specimen is a 10.33 carat, transparent citrine from Brazil, presented in a true Asscher cut with an octagon outline. The dimensions are 12.80 by 12.38 by 9.89 mm, yielding an almost square profile with an approximate length to width ratio of 1.03, and a depth of approximately 78.6 percent when depth is calculated against the average of the length and width. The cutting style is faceted, executed as a traditional step cut, with concentric square step facets on the crown and pavilion converging to a broad table, and with precisely truncated corners to form the octagon silhouette. Clarity is graded as very very slightly included evaluated at eye level, meaning inclusions are minor, located in less optically active zones, and do not interfere with the overall transparency. The color presents as a vivid orange with strong saturation and even distribution across the entire stone, and the finish is an excellent polish that produces sharp, mirror like facet junctions and crisp facet reflections. There has been no enhancement, so the color and clarity are natural, and the gem displays the stability and provenance associated with Brazilian citrine, as offered by The Natural Gemstone Company.

From a light performance and faceting perspective, the Asscher step structure controls the play of light in a way that favors broad flashes and scintillation over pulverized brilliance, this is ideal for a saturated color gem because it emphasizes color saturation while maintaining a refined, architectural face up appearance. The large table and deep pavilion produce a volumetric depth of color, while the step facets create a layered internal architecture that shows parallel hall of mirrors effects when viewed face up. The near square outline and consistent symmetry indicate careful facet alignment, which helps maintain consistent windowing control and reduces the risk of pronounced light leakage in any single direction. The excellent polish enhances near field reflections and ensures that facet boundaries remain distinct, which is particularly important for precision settings that will be viewed under close inspection. The very very slightly included clarity grade evaluated at eye level confirms that at typical viewing distances the stone will appear clean, yet the minor internal features can add character when examined with magnification, a quality appreciated by connoisseurs.

This citrine is especially well suited to custom jewelry because of its size, shape, and depth profile, dimensions that provide both presence and versatility. At 10.33 carats and approximately 12.8 mm across, it is large enough to serve as a dominant center stone in a solitaire or halo ring, or to anchor a pendant with significant visual impact, yet it remains well proportioned for bespoke designs that seek harmony rather than overwhelming scale. The octagon Asscher outline lends itself to both vintage inspired settings that emphasize step facets with milgrain or filigree, and to contemporary designs that use minimal prong or bezel work to showcase the clean geometry. Practical setting considerations include the deep pavilion which benefits from a setting with an open back or a high bezel to avoid excessive contact that could mute the stone, and corner prongs that align with the truncated corners for mechanical security while preserving the geometric shape. Because the cutting shows precise facet symmetry and an excellent polish, it accepts light from a variety of mounting angles, so the gem performs well in both closed back metal colors that enhance warm tones, and in open back settings that maximize transmission and depth of color.

For the custom jeweller and discerning client seeking a natural, statement quality gemstone with technical excellence, this 10.33 carat Asscher citrine from Brazil is a compelling option. Its vivid orange hue, excellent polish, and very very slightly included clarity evaluated at eye level provide a combination of spectacle and refinement, while the octagon Asscher shape and substantial dimensions offer clear pathways for creative design and secure setting engineering. The Natural Gemstone Company stands behind this material with provenance and handling recommendations, and we can provide additional technical data or imagery to assist in design planning, bearing in mind the depth and structural characteristics that will influence bezel heights, prong placements, and light management in the final piece.
