1.70 Ct. Orangish Yellow Citrine from Madagascar

This 1.70 carat round orangish yellow citrine offered by The Natural Gemstone Company presents an exceptional combination of proportions and visual appeal, with exact dimensions of 7.91 x 7.93 x 4.84 mm, a mixed brilliant cut, intense color intensity, and an excellent polish. The mixed brilliant cut marries a traditional brilliant crown with a carefully faceted pavilion, allowing the table and crown facets to capture and return light with lively scintillation, while the pavilion angles create depth and internal reflection. Evaluated at eye level the gem is very slightly included, a clarity characteristic that assures a clean face up appearance with only minor natural features that do not interfere with the gem's overall transparency or performance. Heat treated to achieve its vivid orangish yellow tone, this citrine originates from Madagascar, a source increasingly recognized for producing saturated and stable quartz varieties, and the treatment applied is a standard, stable enhancement that is widely accepted in the trade.

Understanding why this citrine sparkles so effectively requires an appreciation of both its mineral structure and its cut geometry. Citrine is a variety of quartz, composed of silica with a trigonal crystal system, a consistent refractive index in the neighborhood of 1.54 to 1.55, and a modest birefringence. These fundamental optical constants mean that light entering the stone is refracted and internally reflected in predictable ways, and when a cutter applies a mixed brilliant design with precise facet proportions and an excellent polish, the outcome is a lively interplay of brightness and contrast. The intense warm color enhances perceived brilliance by increasing the contrast between bright facet reflections and the gem body color, which can make scintillation appear richer and more saturated than in paler stones. The excellent polish ensures that facet junctions remain crisp, allowing light to bounce cleanly between facets rather than scattering with surface diffusion, a detail that elevates both sparkle and perceived clarity. While quartz has lower dispersion than some high index gems, the combination of precise cutting, intense transparent color, and minimal inclusions produces a signature glow and scintillation that is uniquely appealing among yellow gemstones.

For the educated buyer seeking a gem that balances technical quality with wearable beauty, this Madagascar citrine stands out in several ways. The 1.70 carat weight and near perfectly round dimensions make it an ideal center stone for a ring or pendant, and the mixed brilliant cut yields a classic yet contemporary face up presentation, maximizing light return. The very slightly included clarity grade indicates that the gem will present as visually clean in typical jewelry settings, while still retaining natural origins and character. Heat treatment is disclosed because transparency about enhancements matters to collectors and trade professionals, and this treatment is stable, non invasive, and accepted in the marketplace, contributing to the intense and uniform orangish yellow hue without compromising durability. Origin from Madagascar adds provenance that many buyers value, given the island's reputation for producing well colored and well crystallized quartz, and The Natural Gemstone Company documents and photographs each gem to support confident buying decisions. We recommend a secure setting that protects the girdle and profile for everyday wear, routine cleaning with warm soapy water and a soft brush, and consideration of professional verification if a formal report is desired.
