5.14 Ct. Yellowish Orange Citrine from Brazil

This 5.14 carat round transparent citrine from Brazil is presented by The Natural Gemstone Company, and it exemplifies deliberate lapidary control and material quality, dimensions 11.35 x 11.43 x 7.56 mm, round shape, mixed brilliant faceting, and an excellent polish. The mixed brilliant cut combines a brilliant style crown with a modified pavilion geometry, a configuration selected to optimize both fire and color saturation in natural quartz material. The cutter has maintained tight symmetry in girdle diameter variation, the two diameter numbers indicate an almost perfectly circular outline, and the excellent polish reduces surface diffusion of light to preserve crisp facet junctions. At 5.14 carat the stone delivers a substantial face presence for a round, the weight and diameter relationship suggests efficient material utilization by the cutter to maximize carat yield while avoiding excessive depth loss.

Clarity is graded very very slightly included at eye level, which translates to minimal inclusions that do not detract from visual performance under normal viewing conditions. Inclusions in citrine commonly present as minute crystals or wisps and in this instance they are sufficiently small and well positioned to remain visually unobtrusive, allowing clean light transmission and strong internal reflection. Color is intense with a yellowish orange hue, evenly distributed across the table and pavilion facets, producing a warm, saturated face up appearance without significant zoning. The combination of intense hue and the mixed brilliant facet set produces strong contrast and lively scintillation, particularly under directional light, where the modified pavilion facets deepen tone and the brilliant crown facets return lively pinpoint flashes.

This citrine has been heat treated, a common and stable enhancement for quartz that converts iron related chromophores to produce the desirable yellow to orange palette. Heat treatment in citrine is well understood, it does not involve foreign filling or coating, and when executed correctly it yields permanent color improvement. Origin is Brazil, a source known for clean, well colored quartz specimens that respond predictably to thermal enhancement. The cutter has taken advantage of the material characteristics to set pavilion depth and crown angles that favor color saturation, the given dimensions yield an overall depth about 66.4 percent based on the average diameter, a depth that is somewhat deeper than classical ideal round brilliant proportions, and that deeper profile intentionally intensifies perceived color at the expense of some face up spread. For buyers focused on strong, warm color, that is often a favorable trade off, as the mixed brilliant architecture concentrates light return in the most colorful regions of the stone.

Durability is a key consideration for wearable gemstones, and citrine is quartz, which measures 7 on the Mohs hardness scale. On the Mohs scale, diamond is 10, corundum including sapphire and ruby is 9, topaz is 8, quartz is 7, and common feldspars range down around 6 to 6.5. That position makes citrine substantially more resistant to scratching than most common silicate gems, and suitable for everyday jewelry such as pendants and earrings without excessive concern, and acceptable for rings when set with protective design choices. Because the stone is heat treated and carries an excellent polish, routine cleaning with warm soapy water and a soft brush is recommended, while avoiding abrasive cleaners and harsh mechanical contact. For high wear applications a bezel or low prong setting will protect the girdle and pavilion, and clients who prefer high exposure may choose prong settings with robust prong geometry to minimize impact risk.
