This exceptional pear shape bi color ametrine weighs 7.21 carat and measures 14.83 x 11.95 x 7.55 mm, yielding a length to width ratio of approximately 1.24, an elegant proportion for a classic pear outline. The cutting style is a mixed brilliant cut, combining a brilliant crown to maximize scintillation with carefully calibrated pavilion faceting to preserve color zoning and weight. Facet junctions are precise and symmetrical, producing an excellent polish that emphasizes crisp facet demarcation and strong light return. Coloration displays genuine bicolor character with medium intense saturation, a clear amethyst violet juxtaposed against warm citrine gold, the transition zone being well defined yet harmonious, allowing strong dichroic effects when the stone is rotated. Clarity is evaluated as very very slightly included at eye level, indicating that inclusions are minimal and do not materially affect transparency or brilliance at normal viewing distances. Enhancement is disclosed as heat treated, a stable and common treatment used to refine tonal balance between the purple and yellow zones while retaining natural origin characteristics. Origin is Brazil, a primary source for high quality ametrine, and the specimen exhibits the structural zoning and color distribution consistent with pegmatitic and hydrothermal formation in that region.
