5.59 Ct. Orangish Yellow Citrine from Brazil

This oval orangish yellow citrine weighs 5.59 carats and measures 12.97 x 10.54 x 7.67 mm, a proportion set that yields an approximate depth of sixty five percent when calculated against the average girdle diameter, an intentional proportion that balances light performance with color saturation. The cutting style is faceted, executed as a mixed brilliant cut, with a brilliant facet arrangement across the crown paired with modified step and pavilion facets to concentrate color and control light leakage. The cutter has prioritized crown crownlet proportions and pavilion angles to produce strong internal reflection and scintillation without sacrificing face up size, resulting in a lively balance of brilliance and glow. Polish is graded excellent, with crisp facet junctions and smooth facet planes that maximize light refraction, and symmetry is consistent, with an even girdle thickness that facilitates predictable setting behavior during mounting. Physically this citrine shares the typical gemological constants of quartz, including a refractive index in the range of 1.544 to 1.553, a birefringence of 0.009, a specific gravity near 2.65, and a Mohs hardness of 7, all of which support daily wear in rings or pendants when professionally set.

Optically the stone presents an intense color intensity, an orangish yellow hue that is richer and warmer than the more common pale and pastel yellow citrines seen in the market. The mixed brilliant cutting strategy enhances color distribution, allowing deeper saturation toward the pavilion while preserving a lively face up appearance. Clarity is graded very very slightly included evaluated at eye level, meaning inclusions are minute and difficult to detect without magnification, they do not interfere with light return, and they are effectively masked by the cutter s facet architecture. Heat treatment has been applied, a stable and accepted enhancement for citrine that optimizes hue and saturation without compromising structural integrity, and the result is a uniform, intense orangish yellow that retains excellent stability under normal wear and environmental conditions. Origin Brazil, a region known for producing high quality quartz varieties, contributes to the stone s provenance, and the piece exhibits the clean, saturated character collectors expect from Brazilian material.

Rarity is a defining attribute of this specimen in two dimensions. From a size perspective, citrines above five carats that combine gem quality clarity with a vivid tone are uncommon, because larger quartz crystals frequently show zoning or require aggressive cutting to achieve desirable proportions, which can reduce apparent weight or clarity. From a color perspective, intense orangish yellow citrines are less frequently available than the common golden saffron or pale lemon varieties, particularly in stones that preserve strong brilliance through a mixed brilliant cut. The combination of 5.59 carats, an oval shape optimized for face up impact, an intense orangish yellow hue, very very slightly included clarity at eye level, and an excellent polish therefore places this gem in a small subset of market offerings and makes it particularly well suited for collectors and bespoke designers seeking a focal stone with both presence and technical merit. For mounting recommendations consider ring designs with low to medium profiles to protect the girdle, cathedral prongs to elevate face up color, or bespoke halo settings that can intensify perceived saturation. Care recommendations include routine cleaning with mild detergent and a soft brush, avoidance of sudden temperature extremes, and consideration of professional ultrasonic cleaning only after consultation, given the presence of internal features and the prior heat treatment.
