6.21 Ct. Orangish Yellow Citrine from Brazil

This specimen is a transparent, round shape orangish yellow citrine weighing 6.21 carats with dimensions of 12.25 x 12.19 x 7.37 mm. The cutting style is faceted, executed as a mixed brilliant cut that employs a brilliant facet arrangement on the crown and modified pavilion faceting to preserve weight while maximizing face up color. The measured depth relative to diameter is approximately 60 percent, a proportion that balances light return with retention of carat weight. Clarity is described as very very slightly included, evaluated at eye level, which yields a visually clean window into the stone and permits unimpeded light transmission. Polish is excellent, facet junctions are sharp, and overall symmetry is consistent with precision lapidary work. The stone is unenhanced, natural in origin from Brazil, and presents stable optical and physical properties typical of quartz family materials, including a refractive index range near 1.544 to 1.553, a birefringence on the order of 0.009, low dispersion near 0.013, a specific gravity around 2.65, and a Mohs hardness of about 7.

The mixed brilliant execution influences optical performance in predictable ways. The brilliant style crown with well proportioned star and kite facets increases scintillation and fire in the presence of directional light, while the modified pavilion facets introduce broader flashes and stronger color saturation face up. In practical terms the cutter has optimized crown angle and pavilion depth to encourage return of warm yellow and orange wavelengths rather than dispersing them excessively, so the gem reads as intensely colored when viewed table up. Excellent polish minimizes surface light scattering, and the very very slightly included clarity grade means internal inclusions do not disrupt facet reflection at typical viewing distances. The overall facet architecture produces a balance between bright pinpoint scintillation and larger, lively flashes that convey depth, which is particularly valuable in larger stones above five carats where evenness of color and consistent light performance are essential for high quality face up appearance.

Color analysis of this orangish yellow citrine emphasizes hue, tone, and saturation in practical jewelry contexts. Hue is centered on yellow with a distinct orange component that increases perceived warmth and richness, tone is medium to medium dark in the face up view, and saturation is intense, producing a vivid visual presence without appearing oversaturated or brownish. When set in metal, perceived color shifts are predictable based on the surrounding reflective environment. Set in yellow gold the stone appears to blend with the metal field producing a harmonious warm composition that enhances yellow and orange wavelengths, an effect that is especially flattering on fair skin where it warms the complexion. When set in rose gold the copper tones enhance the orange component and produce an opulent, slightly antique character that flatters warm to neutral undertones. Set in white metal such as white gold or platinum the contrast accentuates the stone as an isolated color focal point, a presentation that suits medium to olive skin tones by emphasizing brightness and chroma. Against deeper or richer complexions the citrine’s intense orangish yellow reads as luminous and highly legible, particularly when paired with a darker metal or a halo of white gemstones that increases perceived vibrancy through contrast.

For design and wear recommendations consider the optical and mechanical attributes together. The 6.21 carat weight and approximately 12.2 mm diameter are ideal for a statement ring, pendant, or cocktail piece, and the mixed brilliant cut responds well to open backed settings that allow light entry from the pavilion, enhancing brightness and perceived color depth. Prong settings with minimal bezel coverage preserve the table view and maximize scintillation, while a low profile bezel with an open gallery can protect the girdle while still permitting light interaction. A halo of small white diamonds or white sapphires will increase color contrast and perceived saturation, whereas a pavé surround in warm metal will harmonize tones for an integrated look. From a care standpoint the stone is durable for regular wear, but abrupt thermal shock and strong acids should be avoided. Clean with warm soapy water and a soft brush for routine maintenance.
