67.45 Ct. Brown Citrine from Ceylon (Sri Lanka)

This gem is a transparent oval brown citrine weighing 67.45 carats, with precise dimensions of 26.49 by 22.41 by 19.62 millimeters, presented in a mixed brilliant cut that marries a brilliant style crown with a modified step pavilion, crafted to enhance both scintillation and color saturation. The cutter retained a substantial pavilion height to preserve weight and to intensify the rich brown gold tone, resulting in a depth that produces a bold presence in hand while maintaining controlled light return across the table. Clarity is graded as very very slightly included at eye level, indicating that internal characteristics are minor and do not materially detract from transparency or brilliance, and polish is graded excellent, with facet planes finished to a high luster and crisp facet junctions that deliver sharp light reflections. Color intensity is intense, with a warm brown palette that reads evenly across the crown and pavilion, and the origin is Ceylon Sri Lanka, a provenance noted for well formed quartz crystals that yield clean, saturated citrine when meticulously selected and cut, enhancement status is none, this material is natural and unheated, and the combination of size, cut, and natural color make this specimen a rare example for collectors and high end jewelry designers.

The mixed brilliant faceting on this oval stone is a deliberate technical choice, the crown exhibits a full brilliant array of star, bezel, and upper girdle facets that optimize scintillation and return of high amplitude flashes, while the pavilion carries larger modified step facets that act to hold and deepen the brown hue, the interface between these two systems has been executed with controlled pavilion angles and precise table proportioning to minimize windowing and to avoid excesive light leakage. The cutter achieved balanced symmetry across the long and short axes, the girdle is consistent, neither overly thick nor extremely thin, providing security for seat mounting without unnecessary loss of weight, and facet alignment displays concentric optical centers that allow the oval outline to read true when set. Because of the specimen size and proportions, this citrine benefits from mounting strategies that support the pavilion and protect the girdle, recommended options include a four or six prong setting with a low profile bezel apron for wearable applications, or a custom crafted open back setting to maximize forward color transmission for collectors who display gemstones loose.

From a gemological perspective this citrine sits squarely within the quartz family, with refractive indices in the expected range for natural citrine, approximately 1.544 to 1.553, and a uniaxial optic sign consistent with crystalline quartz, the material exhibits low to moderate birefringence which is typical for the species and does not interfere with visual clarity in ordinary viewing conditions. Inclusions consistent with the very very slightly included grade are present under careful examination, including minute growth lines and faint two phase or acicular features, these inclusions are predominantly positioned away from the center of the table, which preserves face up transparency and allows for saturated color display, the inclusions act as identifiers of natural origin and do not affect structural integrity, they also provide subtle internal character that distinguishes this stone from laboratory created counterparts. The intense brown tone is the result of natural trace elements and crystal growth conditions in Sri Lankan pegmatitic and hydrothermal environments, and because there is no enhancement the color present is original to the crystal, this authenticity is an important consideration for connoisseurs who demand natural provenance, and The Natural Gemstone Company documents this origin and condition as part of our standard custodial and sales process.

There is a romantic provenance and narrative that accompanies the technical attributes, the brown gold color recalls a late Ceylon afternoon, when low sun passes through tea terraces and ancient forest canopies, the gem captures that moment of warm diminution and holds it within each facet, clarity described as very very slightly included becomes a metaphor for memory, small internal features act like tiny fingerprints of geological time, they are the soft imperfections that make the stone unique and meaningful, when set as a central stone the citrine reads as a jewel that holds story as much as light, The Natural Gemstone Company imagines this gem set in an heirloom ring that connects lineage to landscape, the cutter chose the mixed brilliant approach precisely to retain weight and to keep the glow that seemed to emanate from the Sri Lankan earth when the rough was first illuminated, for buyers who seek both technical excellence and narrative resonance this citrine offers museum quality dimensions combined with tabletop brilliance, we recommend viewing the gem under natural daylight to appreciate the full range of warm brown tones, and our specialists are available to discuss setting options, certification, and bespoke mounting to ensure the gem is showcased in a manner that respects its technical merits and its gentle romantic character.
