2.57 Ct. Brownish Red Citrine from Brazil

This transparent 2.57 carat marquise citrine from Brazil presents precise technical attributes that appeal to discerning gem buyers, offered by The Natural Gemstone Company. The gem measures 14.31 x 6.50 x 5.29 mm, and is cut in a faceted mixed brilliant style that combines pavilion and crown facets to optimize light return. The stone displays a brownish red hue with vivid color intensity, and is graded very very slightly included when evaluated at eye level, indicating exceptional clarity for a natural citrine. The polish is excellent, and the specimen is unenhanced, confirming that its color and clarity are natural rather than the result of heat or other treatments. The marquise outline accentuates the stone length and creates an elegant profile for calibrated settings, while the mixed brilliant faceting produces controlled reflections across the elongated surface.

When compared to more common gemstones, this citrine exhibits a distinct balance of sparkle and warm color that sets it apart from standard quartz and other colored stones. As a variety of quartz, citrine has a refractive index near 1.55, which yields a softer but broad white light return in comparison to higher index gems such as topaz or tourmaline, and considerably less fire than diamond which has a refractive index above 2.40. The mixed brilliant cut in this marquise maximizes the available brilliance for citrine by using strategic facet angles to enhance internal reflections, producing lively scintillation that is often more expansive and uniform than the narrow flashes seen in many step cut stones. The vivid brownish red tone of this specimen introduces an uncommon depth within the citrine family, making its apparent brightness and warmth more noticeable alongside yellow and pale orange citrines. In practical terms, the gem will read as visually more dynamic than typical commercial quartz material, and its natural, untreated origin increases its market distinction because many citrines are heat altered. For applications in rings and pendants where both color saturation and controlled brilliance are desired, this marquise citrine offers a refined balance of optical performance and natural character, and its precise measurements and grading support accurate design and setting decisions.
