0.95 Ct.Tw.Total Carat Weight Yellowish Orange Citrine Pair from Brazil

This pair of transparent citrines presents a precise combination of size, color, and finish. The stones weigh 0.47 carats and 0.48 carats respectively, and are round in shape, yellowish orange in hue. They measure 5.03 by 5.07 by 3.57 millimeters and 5.07 by 5.12 by 3.62 millimeters, and are fashioned in a mixed brilliant cut. Each stone is evaluated as eye clean at eye level, with vivid color intensity and an excellent polish. The material has been heat treated, a standard and stable enhancement for citrine, and the pair originates from Brazil. For context and design pairing, note that the complementary opal type available is White Opal, which offers a balanced contrast to these warm tones. The Natural Gemstone Company provides this information to ensure full transparency of specifications and provenance.

The distinctive sparkle of these citrines arises from an interplay of internal crystal structure, optical properties, and precise cutting. Citrine is a variety of quartz, a silicon dioxide crystal in the trigonal system, with a refractive index around 1.544 to 1.553. This refractive index allows efficient transmission and internal reflection of light when combined with the mixed brilliant facet architecture. The mixed brilliant cut merges brilliant style facets on the crown with controlled pavilion faceting, optimizing both scintillation and return of light to the viewer. With an excellent polish and accurate facet junctions, light entering the gem is refracted and redirected through numerous internal facets, producing rapid points of brightness and contrast across the stone surface. The high transparency and eye clean clarity permit unobstructed light travel, enhancing brightness and dynamic sparkle, while the vivid yellowish orange saturation gives the reflected light warm, lively tones rather than muted glints. Heat treatment stabilizes and intensifies the color uniformly, allowing the optical effects to remain consistent under various lighting conditions. Taken together, the structural qualities of the quartz lattice, the chosen mixed brilliant cutting geometry, the meticulous polish, and the material clarity deliver a lively, well defined sparkle that is distinctive for citrine, and is presented with full specification and provenance by The Natural Gemstone Company.
