4.38 Ct. Yellow Citrine from Brazil

This transparent yellow citrine weighs 4.38 carats, and its measured dimensions are 12.44 by 9.65 by 6.37 millimeters, an oval outline that balances face up presence with wearable depth. The cutting style is faceted with a mixed brilliant design, combining a modified brilliant crown with a step adjusted pavilion, a configuration chosen to maximize return of light while preserving color saturation. Clarity is graded as very very slightly included when evaluated at eye level, a grade that indicates inclusions are minute and do not detract from overall transparency or brilliance. Color intensity is described as intense, a vivid warm yellow that reads strongly in both daylight and artificial lighting, and the surface finish is an excellent polish that yields crisp facet junctions and lively scintillation. Enhancement is disclosed as heat treated, a common and stable process in citrine production, and the documented origin is Brazil, a region renowned for producing clean, well colored quartz material. The Natural Gemstone Company presents this gem with full disclosure of its technical attributes and a focus on the craftsmanship that shaped it.

The journey of this citrine began as a crystalline form embedded in pegmatitic and hydrothermal veins within Brazilian host rock, where silica rich fluids deposited quartz over geological time. Local miners identified a quality rough that exhibited good transparency and an initial warm tone, sometimes present in natural citrine, sometimes present in amethyst or smoky quartz varieties destined for controlled enhancement. The rough was selected for size and color potential, and it entered a sorting phase where material was evaluated for homogeneity, internal characteristics, and cutting yield. Heat treatment was applied under monitored conditions to stabilize the desired yellow hue, a process that alters iron related chromophores to achieve a consistent golden tone, without compromising clarity. Throughout this stage chain of custody documentation was maintained to ensure traceability from the mine region in Brazil through local cutters and onward to our facility. The Natural Gemstone Company emphasizes ethical sourcing and full disclosure, and the documentation accompanying this stone reflects its provenance, treatment history, and the steps taken to bring a superior rough specimen into a finished gem.

In the cutting studio the lapidary selected a mixed brilliant configuration to exploit the oval proportions, creating a crown architecture with a central table facet that measures proportionally to the overall width, bounded by star facets and kite facets that feed light to a precisely polished girdle. The pavilion features a modified step to concentrate color toward the center while preserving light return, a technique particularly effective with intensely colored citrines, because it deepens the apparent saturation without creating a dark, windowed appearance. Symmetry was controlled to within tight tolerances, ensuring facet alignment that produces consistent octahedral scintillation across the table and well balanced dispersion around the girdle. The cutter addressed the very very slightly included clarity by orienting the stone so that minor feather inclusions reside near facet junctions or under the crown where they have minimal visual impact, a deliberate decision that maintains an eye clean presentation. The final polish was executed with fine diamond pastes and strict inspection, yielding an excellent finish that enhances light performance and ensures that facet edges are sharp and reflective. The resulting 4.38 carat oval sits with ideal proportions for a single stone ring, a pendant, or a bespoke setting where the mixed brilliant cut will read as lively and saturated under varied lighting conditions.

When this citrine arrived at The Natural Gemstone Company it underwent final quality control and photographic documentation, including scale reference images taken on a hand to aid buyers in assessing visual size and presence. The gem is ready for setting, and we provide technical guidance for jewelers on ideal mounting considerations, recommending a bezel or four claw setting that secures the oval outline while allowing light to enter the pavilion aperture, preserving the brilliance achieved by the cutter. For maximum color contrast and classic warmth consider yellow gold or rose gold alloys, which complement the intense yellow and enhance perceived saturation, while white metals provide a contemporary contrast that emphasizes fire and clarity. Care instructions are straightforward, warm soap and water with a soft brush for routine cleaning, avoiding prolonged exposure to harsh chemicals or extreme heat, and periodic professional inspection to ensure the setting remains secure. We offer certification documentation on request and recommend photography under standardized lighting for appraisal and insurance purposes. The Natural Gemstone Company stands behind its presentation and offers detailed provenance and treatment records, making this citrine a transparent purchase for collectors and designers who value technical precision.

This gemstone embodies a clear narrative from geological formation through human intervention, each phase informed by technical choice and artisanal skill, a chain that began in Brazilian veins and concluded in a precisely faceted, polished, intensely colored oval. The decision to employ a mixed brilliant cut reflects a calculated balance between brilliance and color retention, and the heat treatment was applied to achieve uniform intensity without masking the stones natural potential. With a clarity grade evaluated at eye level as very very slightly included, the gem offers near flawless appearance to the naked eye, combined with an excellent polish that accentuates facet crispness and sparkle. For the buyer who appreciates the intricacies of faceting angles, color grading, inclusion management, and surface finishing, this 4.38 carat citrine represents a consummate example of technical excellence and ethical sourcing, offered with the full provenance and support of The Natural Gemstone Company, ready to become the centerpiece of a considered jewelry commission or a finely curated collection.
