6.57 Ct. Citrine from Ceylon (Sri Lanka)

This cushion shape yellow citrine is a finely proportioned gem weighing 6.57 carats, a weight that places it well above the more common small sizes frequently encountered for this species, and that contributes directly to its presence and value. The dimensions are 11.76 by 11.70 by 7.81 millimeters, providing a substantial table and pavilion depth that work together with the mixed brilliant cut to deliver balanced light return and scintillation. The mixed brilliant faceting pattern blends step and brilliant elements, allowing broad flashes across the crown while maintaining focused brilliance from the pavilion facets. The vivid color intensity is a primary characteristic of this stone, producing a lively yellow that reads as pure and saturated without apparent zoning, and the excellent polish enhances surface luster so that the stone presents a clean, mirror like finish under inspection. The Natural Gemstone Company offers this citrine as a specimen where carat weight and optical refinement combine to create an item suited to quality jewelry design.

Detailed assessment information supports the stone as a premium yellow citrine by common trade standards, and the clarity grade is stated as very slightly included when evaluated at eye level, indicating only minor internal features that do not materially detract from visual performance or durability. The enhancement disclosed is heat treated, a stable and widely accepted treatment for citrine that intensifies warm yellow tones while preserving clarity and structural integrity. Origin is Ceylon Sri Lanka, a source known for producing well colored quartz varieties, and provenance adds contextual value for collectors and designers who consider geographic attribution important. The mixed brilliant cut, executed with attention to symmetry and facet junctions, yields consistent reflections and a pleasing pattern at the table, while the proportions indicated by the dimensions support robust light return and comfortable setting margins for prongs or bezel work.

From a practical perspective, a 6.57 carat citrine of these proportions is versatile for ring, pendant, or bespoke pieces, offering ample visual impact without excessive bulk, and it is particularly well suited to center stone roles where weight and face up size are desired. Setting considerations include allowing for secure prong work that preserves the cushion outline while protecting the girdle and culet areas, and designers may choose open back settings to maximize brilliance or closed back mounts to emphasize color saturation. Care recommendations are standard for heat treated quartz, and the gem responds well to routine cleaning with mild soap and warm water, avoiding harsh chemicals and extreme thermal shock.
