12.68 Ct. Purple Amethyst from Brazil

This exceptional transparent purple amethyst weighs 12.68 carats, and measures 16.94 x 14.04 x 9.85 mm, presented in a classic oval shape that maximizes table size and face up presence. The stone is faceted in a mixed brilliant cut, combining precise pavilion facets with a well proportioned crown to enhance brilliance and light return. Color is vivid and evenly distributed across the gem, and polish is excellent, resulting in crisp facet junctions and lively scintillation. Clarity is graded very very slightly included, evaluated at eye level, which means the stone appears clean to the unaided eye while retaining natural internal character when viewed under magnification. This amethyst is untreated, no enhancement, and originates from Brazil, a region renowned for producing rich, gem quality amethyst crystals. The combination of transparency, vivid color intensity, and excellent polish confirms the gem as a natural, high quality specimen suitable for fine jewellery.

For the educated buyer, this gem stands out because of its size and clarity, which together create an unmistakable statement piece. At 12.68 carats and with a generous oval dimension, the stone reads large on the finger or as a pendant center, offering presence without needing elaborate settings to appear impressive. The mixed brilliant cut optimizes fire and brilliance while preserving weight, making this gem ideal for designers and collectors who value both optical performance and efficient material use. The very very slightly included clarity grade is a practical advantage, as minor inclusions do not detract from the visual impact but do verify natural origin, and the absence of enhancement increases market desirability and long term value. Origin from Brazil further supports provenance, as Brazilian amethyst is sought after for its depth of color and stability. At The Natural Gemstone Company we present this amethyst as a premium, ethically sourced option for a bold solitaire ring, an elevated pendant, or a bespoke commission that requires a central stone with exceptional color, clarity, and presence.
