4.91 Ct. Ametrine from Brazil

This listing presents a transparent bi color ametrine weighing 4.91 carat, carefully fashioned into a cushion shape that measures 13.34 by 9.09 by 6.50 mm. The gem displays a mixed brilliant cut, combining the scintillating fire of brilliant faceting with the elegant depth of pavilion facet work, producing lively return of light and a balanced face up presence. Coloration is medium light in intensity, with the defining ametrine transition evident between soft violet and warm golden tones, and the bi color zoning reads cleanly across the table with pleasing symmetry. Clarity is graded as very very slightly included when evaluated at eye level, which yields a visually clean appearance to the wearer and preserves excellent transparency, while the surface finish is reported as an excellent polish that maximizes brilliance and ideal optical performance. This piece originates from Brazil and has undergone heat treatment as a standard enhancement to optimize hue and saturation, undertaken with care to preserve the crystal integrity and the natural duality that characterizes ametrine.

The proportions and facet design make this stone well suited for a variety of settings, including solitaire rings where table size and depth contribute to a commanding wrist presence, or as a refined focal point in a pendant where the bi color contrast can be appreciated from multiple viewing angles. The mixed brilliant cut aids in dispersing light evenly through both the violet and golden zones, reducing the appearance of color banding under most lighting conditions, while the very very slightly included clarity grade means that the gem sits near the top tier of eye clean material for its size. Measurements and weight are aligned with what one would expect for a substantial cushion form, and the excellent polish ensures that faceting lines remain crisp and that metalwork can be set to sit flush and finish cleanly. As with all heat treated gemstones, standard precautions should be observed when resizing or undertaking metalwork to avoid unnecessary thermal shock, and routine cleaning with warm soapy water and a soft brush is recommended to maintain luster.

There is a natural poetry to a gem that simultaneously embraces two colors, and this ametrine conveys a quiet narrative through its hue and clarity. The violet tone reads as the evening afterglow, composed and introspective, while the golden facet suggests the first warm light of morning, hopeful and clear. Together these tones form a subtle dialogue that mirrors the story of two lives converging, a harmony of contrast that is neither shouted nor muted, but sustained in a gentle equilibrium. The near eye clean clarity is part of that narrative, a transparency that speaks to openness and trust, and the mixed brilliant faceting is a metaphor for shared perspective, where different planes of experience catch the light in complementary ways. At The Natural Gemstone Company we present this ametrine as both a technical specimen and an emblem of balanced partnership, a gem that is equally at home in considered jewelry designs and in collections where provenance and measured quality matter.
