5.03 Ct.Tw.Total Carat Weight Citrine Pair from Brazil

This matched pair of transparent Brazilian citrines from The Natural Gemstone Company presents an exacting combination of measurements and finish that will appeal to technically minded designers, craftsmen, and collectors, the stones weigh 2.43 carats and 2.60 carats respectively, and are fashioned into round shapes with mixed brilliant cuts, their dimensions are 9.13 by 9.24 by 5.59 millimeters and 9.20 by 9.14 by 5.82 millimeters, the clarity is graded as very very slightly included when evaluated at eye level, the color exhibits a medium intensity yellow, the polish has been graded excellent, and the material has been enhanced by stable heat treatment, the documented origin is Brazil. The near match in diameter and the small 0.17 carat weight differential make this pair particularly well suited for matched applications such as stud earrings or balanced pendant sets, the precision of the cutting and the close tolerance in size facilitate predictable CAD modeling and setting seat design.

From a faceting and proportion perspective these citrines are cut as mixed brilliants, combining a brilliant style crown with a modified pavilion, this approach typically yields a facet architecture that optimizes face up brilliance while preserving color saturation, the mixed approach commonly results in an effective facet count near the classical 58 facets but with pavilion modifications tailored to the rough, the measured depths correspond to approximately 61 percent and 63.5 percent of the mean diameters for each stone respectively, these depth profiles lie within the practical design window that balances light return with perceived color, the table proportions have been executed to favor scintillation across the crown facets while avoiding excessive windowing, the excellent polish enhances microfacet reflection and contributes to crisp facet junctions, the refractive index of quartz in this color range is approximately 1.544 to 1.553 and the material specific gravity is near 2.65, these physical constants are useful when calculating setting stresses and determining bezel wall thickness for mechanical retention.

The clarity and color characteristics are well documented for integration into high end and production jewelry, the stones read as eye clean with only very very slight inclusions under typical visual inspection, these inclusions are unlikely to impact durability or overall optical performance and will generally be masked by prong placement or bezel seating, the medium color intensity produces a warm yellow that reads clean and saturated in natural and artificial light, because the stones have been heat treated to stabilize and intensify that yellow hue the color is permanent under normal wear conditions, the relatively low birefringence of quartz means that orientation during setting has limited influence on optical doubling, however orienting the table and pavilion to the wearer commonly optimizes face up color and brilliancy, designers should note that citrine hardness indexes near seven on the Mohs scale so standard protective considerations for daily wear are recommended.

The customizability of these rounds is extensive and technically straightforward for varied jewelry applications, for precision stud earrings a four or six prong setting will reveal the crown and maximize brilliance while providing minimal metal intrusion, a semi bezel or full bezel will sacrifice a small amount of crown visibility but will offer superior edge protection for everyday wear, for pendants and drop designs a low profile setting with a shallow bezel seat matched to a depth of approximately 5.6 to 5.8 millimeters will secure the pavilion without lifting the stone excessively from the plate, for rings where the stones serve as center stones a three stone or halo configuration can be designed with calibrated accent diamonds using common sizes to follow the face up diameter, when designing halos allow a minimum clearance of 0.2 to 0.3 millimeters between the citrine girdle and the inner edge of the halo to ensure symmetry and avoid stress concentrations, tension settings should be approached with caution because quartz is anisotropic and can be susceptible to set induced fractures if excessive localized force is applied to the girdle.

These citrines pair exceptionally well with warm metal palettes and complementary or contrasting accent stones, yellow and rose gold will amplify the warm yellow tone for a cohesive look, while white gold and platinum provide a high contrast that emphasizes the stone color against cooler metal, pairing with small melee diamonds and warm champagne diamonds will increase perceived brightness without overpowering the citrine, for designers seeking color contrast consider small blue sapphires or green tourmalines to create directional color dynamics, the close match in size and optical behavior makes the pair ideal for symmetrical earring designs, matched pendant pairs, or twin accent stones flanking a larger center stone, The Natural Gemstone Company is available to provide additional services including custom recutting to tight dimensional tolerances, bespoke matching for multi stone assemblies, and technical support for CAD files and setting specifications, for buyers and manufacturers seeking predictable integration these citrines present a well documented and versatile option that translates readily into a wide variety of jewelry forms.
