5.15 Ct. Yellow Citrine from Brazil

This specimen is a natural yellow citrine presented in a radiant shape, weighing 5.15 carats, and cut in a faceted radiant style. The measured proportions are 10.38 x 10.26 x 7.29 mm, giving the stone a balanced table and pavilion relationship that supports both depth and surface presence. Origin is Brazil, and the stone carries no enhancement, confirming that its color and clarity are natural attributes rather than the result of heat treatment or other modifications. Clarity is graded as eye clean when evaluated at eye level, which means the gem appears free of inclusions to the unaided eye under standard viewing conditions. Polish has been evaluated as excellent, and color intensity is classified as intense, producing a vivid golden yellow that holds saturation across the facets. The Natural Gemstone Company offers this citrine as a fully natural, unenhanced example of Brazilian material that combines reliable proportions with a gemological profile suited to precision jewelry settings.

Optical performance of this radiant cut citrine emphasizes a combination of lively brilliance and controlled dispersion. The radiant cut facet arrangement integrates trimmed corners with a mixed cutting style that yields scintillation when the stone is set and moved. The intense yellow hue is distributed evenly across the crown and pavilion, and the excellent polish assists in maximizing surface reflectivity and overall luster. Faceting has been executed to maintain symmetry and to present an attractive table window while also preserving internal fire. Under direct illumination the stone exhibits a warm golden flash with secondary facets contributing to a finely faceted scintillation pattern. These attributes make the gem adaptable to a variety of mounting styles, from open gallery settings that showcase light transmission to closed back designs where color dominance is preferred.

Inclusions in natural gemstones serve as unique internal fingerprints, and this citrine is no exception. Although the gem is eye clean at normal viewing distances, microscopy and loupe examination can reveal minor features typical of natural quartz family material, including fine growth zoning and isolated crystal or fluid inclusions. These internal characteristics are not defects in the ordinary sense, but rather evidence of the stone formation environment, and they provide a provenance narrative that synthetic or treated material cannot replicate. Inclusions act as identifiers because their patterns and relationships reflect the crystalline growth history and the geological conditions of the host deposit in Brazil. For gemologists and experienced collectors, such features aid in confirming natural origin and in distinguishing individual stones from one another. The absence of treatment combined with the presence of typical natural markers increases the specimen value for those who prioritize unenhanced and verifiable natural gems.

From a practical perspective the 5.15 carat weight and the 10.38 x 10.26 x 7.29 mm dimensions make this citrine suitable for a central stone in a ring, pendant, or tailored cufflink design. The radiant cut provides secure girdle geometry for bezel or prong mountings while offering facet complexity that remains visible when set. Citrine belongs to the quartz family with a Mohs hardness of approximately seven, which affords reasonable resistance to wear for daily jewelry when appropriate care is taken. Routine cleaning with mild soapy water and a soft brush will preserve luster, and ultrasonic cleaners may be used cautiously given the individual characteristics of the mount. The Natural Gemstone Company is available to provide additional gemological information, detailed images, and advice on settings and care, ensuring that the stone is matched to the intended design and usage parameters. This citrine represents a transparent, intense, and characterful example of unenhanced Brazilian material suitable for both fine jewelry and curated gemstone collections.
