5.73 Ct. Citrine from Brazil

This transparent 5.73 carat, emerald cut, orangish yellow citrine measures 11.68 x 9.91 x 6.99 mm, clarity grade very slightly included evaluated at eye level, medium color intensity, excellent polish, heat treated, origin Brazil. The emerald cut presents long step facets and truncated corners, producing broad flashes of color and a hall of mirrors effect that emphasizes tone and clarity rather than brilliant scintillation. As a quartz, the stone benefits from a refractive index in the 1.544 to 1.553 range, low birefringence, specific gravity near 2.65, and a Mohs hardness of 7, which combines adequate daily wear durability with the ability to accept very fine facet edges during cutting. The heat treatment is a standard, stable enhancement used to deepen orange yellow tones and to create a uniform face up color, the result is a clean table and crisp facet junctions allowed by the excellent polish. At 11.68 by 9.91 millimeters the proportions are well balanced for both solitaire and halo settings, and the step cut maximizes the apparent size and color depth for collectors who prioritize hue and internal character.

In historic context this citrine evokes the warm, saturated presence associated with famous yellow gems such as the Tiffany Yellow Diamond, while remaining a distinct material with quartz optical behavior and significantly different provenance and price point. Its medium color intensity and orangish yellow hue recall the golden tone of celebrated museum stones, yet the emerald cut favors broad color planes similar to classical table cuts seen in period jewelry, making this example particularly suitable for designs that reference vintage aesthetics. Compared with historically significant diamonds and rare colored stones, this Brazilian citrine offers a combination of substantial carat weight, clean eye level appearance, and stable enhancement that makes it an exceptional value for connoisseurs. The Natural Gemstone Company presents this gem as a study in controlled color, precision faceting, and practical durability, ideal for clients seeking a large, well cut step cut citrine with documented origin and treatment.
