8.85 Ct.Tw.Total Carat Weight Greenish Yellow (Lemon Quartz) Quartz Pair from Brazil

This matched pair comprises two transparent lemon quartz gemstones weighing 4.39 carats and 4.46 carats respectively, cut in a princess shape with highly controlled proportions, originating from Brazil and offered by The Natural Gemstone Company. Each stone measures 10.13 x 10.09 x 6.41 millimeters and 10.16 x 10.12 x 6.54 millimeters, demonstrating exceptional size uniformity for a matched set. The gems have been treated by irradiation to induce their greenish yellow hue, a standard enhancement in the trade that yields a stable and evenly distributed color when executed under professional conditions. Both stones exhibit an excellent polish, ensuring minimal surface diffusion of light loss at the facet junctions, and their finishing quality supports precise table alignment and crisp facet intersections that are critical for predictable light performance in finished jewelry.

From a cutting and lapidary standpoint, these pieces are fashioned as classic princess cuts, a square step modified brilliant that combines a faceted crown and pavilion architecture to maximize scintillation in materials with the refractive index characteristic of quartz. The depth proportions of these stones calculate to approximately 63.4 percent for the 4.39 carat stone and 64.5 percent for the 4.46 carat stone based on the stated dimensions, percentages that fall within the effective range for princess cut designs and promote balanced internal reflection rather than excessive light leakage through the pavilion. The facet geometry produces defined pavilion chevrons and a square table that channel light back through the crown facets, compensating for quartzs relatively low dispersion by emphasizing contrast and flash instead of fire. Clarity is graded as very slightly included at eye level, indicating minor internal features that do not materially interrupt light transmission or structural integrity, and the excellent polish and well-controlled facet angles minimize surface and internal scattering for a clean visual appearance.

Optical and material properties of quartz are significant for practical design decisions and long term wear considerations. Quartz has a refractive index around 1.544 to 1.553 and a uniaxial optic character with birefringence near 0.009, meaning that while it will not exhibit the high dispersion of gemstones such as diamond or garnet, a well-executed princess cut can still produce lively scintillation and crisp directional flashes. The medium color intensity of these lemon quartz specimens is evenly saturated across each stone, so paired placements such as earrings or a matched trilogy setting will appear consistent without the need for additional color correction. The irradiation enhancement responsible for the greenish yellow tone is widely used for quartz and is effectively permanent under normal wear, though prolonged exposure to extreme heat or aggressive chemical environments should be avoided to maintain maximum color stability. Hardness on the Mohs scale at approximately seven gives these stones respectable scratch resistance for everyday jewelry, while the cut and thickness provide sufficient material for secure prong, bezel, or semi-bezel retention.

The versatility of this matched pair lends itself to a broad spectrum of jewelry applications, from precision set stud earrings and matched cufflinks to complementary accents in multi-stone ring and pendant compositions. Their square footprint and controlled depth make them well suited for four or four plus corner prong settings that protect the pointed corners, as well as bezel and channel settings where clean lines and modern geometry are desired. Designers will appreciate the stones as centerpieces in asymmetric or geometric layouts because the princess cut presents strong linear facet patterns that align well with architectural metalwork and pavé diamond accents, where quartzs lower dispersion will not visually compete with high dispersion side stones. For settings that demand maximum light return, a shallow under-bezel or open gallery will preserve the pavilion angles and allow the coordinated chevron facets to reflect light efficiently, while matched mounting tolerances should account for the small difference in depth between the two stones to ensure identical face-up alignment. For buyers and designers seeking technical consistency and aesthetic adaptability, The Natural Gemstone Company presents this pair as a precision matched option, combining reliable optical behavior, stable irradiation-enhanced color, and lapidary craftsmanship that supports a wide range of refined jewelry creations.
