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

The Natural Gemstone Company presents a matched pair of oval yellow citrines, 3.06 carats and 3.05 carats, precision cut for balanced face up presence and optical performance. The first stone measures 11.10 x 8.93 x 5.68 millimeters, the second stone measures 10.85 x 8.74 x 5.88 millimeters. The length to width ratios are approximately 1.24 to 1 for both stones, yielding a classic slightly elongated oval profile that preserves optical symmetry in paired settings. The mixed brilliant cut integrates a brilliant style crown with a more economical pavilion geometry to optimize scintillation and face up spread while maintaining carat retention. Depths translate to approximately 56.7 percent for the larger oval and approximately 60.0 percent for the slightly deeper companion, a deliberate trade off between table size and pavilion depth designed to maximize internal reflection for quartz with its optical constants. Facet junctions and facet symmetry were executed to exacting standards given the excellent polish grade, resulting in crisp facet planes that act as efficient mirrors for transmitted and reflected light.

Clarity and color specifications are calibrated for discerning buyers who value clean, transparent material. Both stones are graded eye clean when evaluated at eye level, indicating an absence of any inclusions that would interrupt light pathways or create visible clouds under normal viewing. Color is described as medium intense yellow, with even saturation and minimal zoning, characteristics that respond well to mixed brilliant faceting which enhances color concentration toward the pavilion and produces attractive honey to sunny yellow face up tones. These citrines have been heat treated, a standard and stable enhancement for quartz to achieve consistent warm hues, and the treatment is permanent under normal wearing conditions. Origin is Brazil, a well known source for clean, well colored citrine rough, and the provenance supports predictable crystal habit and cutting behavior. As a matched pair, the stones exhibit near identical visual weight, color tone, and facet pattern, making them ideal for high quality matched earrings or for a balanced two stone pendant application.

When comparing brilliance and reflection characteristics to other common gem species, the optical behavior of citrine must be understood in terms of refractive index and dispersion. Citrine is a variety of quartz, with a refractive index in the range of approximately 1.544 to 1.553, and a dispersion value near 0.013. These numbers place citrine below higher index and higher dispersion gems such as diamond which has a refractive index of about 2.42 and dispersion near 0.044, and below garnet and sapphire which have higher indices that produce stronger face up brightness and greater contrast. In practical terms, citrine offers moderate brilliance and a lively vitreous luster, but it will not display the same degree of fire or intense light return as stones with greater refractive power. Compared to topaz which has a refractive index around 1.61, citrine returns slightly less brightness, however its lower dispersion yields cleaner, more saturated flashes of color rather than spectral fire. Pleochroism in citrine is negligible, so the stones present a uniform yellow color from multiple viewing angles, enhancing predictability in jewelry design.

The mixed brilliant cutting strategy used for these ovals is particularly well matched to the optical profile of quartz. By employing a brilliant style crown, the cutters create a high density of small facet mirrors that increase scintillation and give lively reflection on movement, while a moderately deep pavilion preserves color saturation and internal reflection without sacrificing too much face up spread. The excellent polish ensures minimal scattering at facet borders, so the light paths remain coherent and produce crisp highlights. For customers familiar with gem optics, these citrines represent an efficient balance between optical performance, carat economy, and matched pair aesthetics. The Natural Gemstone Company stands behind the technical quality and provenance of these stones, and they are presented ready for precision mounting where their matched proportions and controlled color will read as a harmonious ensemble in fine jewelry.
