8.72 Ct. Madeira Citrine from Bolivia

One transparent 8.72 carat cushion shape orangish brown Madeira citrine is presented with precise specifications, weight 8.72 carats, dimensions 14.60 x 11.01 x 8.53 mm, mixed brilliant cut, clarity grade very very slightly included, evaluated at eye level, intense color intensity, and excellent polish. The cushion outline and mixed brilliant facet arrangement yield balanced light return and controlled scintillation, while the stone maintains high transparency and even tone across the table and pavilion. The polish is meticulous, producing crisp facet junctions and a clean surface finish, and the gem is free of enhancement, unheated and natural in origin from Bolivia. These objective attributes make the piece well suited for a finely executed ring or pendant, where its depth of color and measured brilliance can be appreciated without distraction.

The narrative of formation begins millions of years ago deep within the Bolivian crust, where silica rich fluids circulated through fractures and cavities in host rocks during periods of regional magmatism and hydrothermal activity. Under sustained heat and pressure, quartz crystallized from these fluids, and trace amounts of iron were incorporated into the growing crystal lattice. Over prolonged thermal histories and subtle changes in oxidation conditions, the iron imparted the characteristic orangish brown Madeira hue that distinguishes this variety of citrine. Subsequent geological uplift and erosion exposed the mineralized veins to the surface, where the rough material was recovered and later fashioned by a cutter intent on preserving color saturation and clarity. The resulting gem, cut to a mixed brilliant pavilion and crown geometry, reflects both its deep geological history and the modern skill applied in its shaping. The Natural Gemstone Company documents this specimen as natural, unenhanced Madeira citrine from Bolivia, and stands ready to provide additional gemological information and high resolution imagery upon request.
