4.02 Ct. Ametrine from Brazil

This transparent 4.02 carat cushion shape bi color ametrine is presented with precise cutting and finishing to meet exacting standards, with dimensions of 11.71 by 8.33 by 6.82 millimeters. The mixed brilliant cut combines step and brilliant faceting to balance scintillation and windowed color, and the excellent polish enhances light return across the pavilion and crown. Clarity is graded as eye clean when evaluated at eye level, and the medium light color intensity delivers a refined, wearable saturation that reads as a harmonious blend of amethyst purple and citrine golden tones. The specimen has been heat treated to stabilize and even its hues, and it originates from Brazil, a noted source for fine ametrine material. With the inherent toughness of quartz and a Mohs hardness of approximately 7, this gem is suitable for a daily wear ring when set and handled with customary care.

As an engagement option this bi color ametrine presents a distinctive alternative to traditional single hue stones, offering inherent symbolism in its dual tones and a visual depth that changes with viewing angle and light conditions. The cushion shape provides a classic silhouette that sits comfortably in solitaire, halo, or three stone settings, while the 11.71 by 8.33 millimeter table presents a substantial face up presence without overwhelming delicate settings. For longevity, a secure prong or bezel setting is recommended, and routine care should avoid blunt impact and prolonged exposure to strong acids or abrasive cleaners. Offered by The Natural Gemstone Company, this ametrine combines gemological integrity and aesthetic versatility, making it an articulate choice for a bespoke engagement piece that emphasizes individuality, enduring wearability, and a refined interplay of color and light.
