18.27 Ct. Citrine from Brazil

This transparent 18.27 carat yellowish orange citrine from Brazil is presented by The Natural Gemstone Company as a refined option for bespoke jewelry projects. The combination of substantial carat weight and a precise trillion shape gives this stone a distinctive presence that translates directly into design versatility. The overall tone of the stone is warm and inviting, with an intense color saturation that is consistent across the table and crown, providing an even field of color that reads clearly to the naked eye. The trillion cut emphasizes the triangular silhouette while preserving depth and proportion, producing a balance of brilliance and color dispersion that suits both modern and classic design languages.

Measured at 17.99 by 17.57 by 9.57 millimeters, this citrine occupies a significant footprint while maintaining proportions that are favorable for secure settings. The diameter across the girdle near 18 millimeters places it in a size range often selected for center stones in rings and pendants, while the 9.57 millimeter depth indicates a well executed pavilion that supports light return without appearing shallow. The stone is graded eye clean, evaluated at eye level, which means no inclusions are visible without magnification and the visual field is clean and unobstructed. The excellent polish on facet junctions results in crisp facet reflections and smooth table and pavilion planes, enhancing perceived brightness. There has been no enhancement performed on this specimen, and the natural Brazilian origin contributes to its trace mineral profile and hue stability.

The trillion shape is particularly advantageous for custom work because its triangular outline offers strong design cues while being adaptable to multiple mounting approaches. As a primary center stone, the three equal sides provide opportunities for symmetric bezel work, three point prong settings, or a halo that follows the triangular silhouette. The size and thickness support secure prong placement or a partial bezel edge without compromising the visible face up area. Designers often exploit the acute angles of a trillion to create dynamic settings that emphasize the stone geometry, or they pair the stone with tapered side stones to create a graduated composition. Given the warm yellowish orange color, considerations of metal choice are straightforward, with yellow gold and rose gold complementing and amplifying the warmth, and white gold or platinum introducing contrast that can accentuate brilliance and clarity. The stone also lends itself to brooch and high jewelry applications where a clear, intensely colored triangular form can read as a primary motif.

From a practical standpoint the combination of intense color, eye clean clarity, and excellent polish simplifies both selection and setting decisions for custom projects. The absence of enhancements reduces the need for special disclosure and supports long term color stability under normal wear conditions. Routine care for citrine includes avoidance of prolonged exposure to high heat and harsh chemicals, and periodic professional inspection of the setting to ensure prongs and mounts remain secure. At The Natural Gemstone Company we can provide additional measurements, high resolution images, and light performance views on request to aid in the technical planning of a setting. If you are developing a custom piece and require exact facet orientations, recommendations for prong count, or suggestions on metal pairing, we are available to advise based on the physical characteristics of this 18.27 carat trillion citrine and your intended design goals.
