11.05 Ct. Ametrine from Bolivia

When you are searching for a single stone that will end your quest for the ideal engagement ring or the rare centerpiece for a private collection, this gem answers that need with clarity and confidence. This is one beautiful transparent 11.05 carat asscher octagon shape bi color ametrine, with precise dimensions of 15.26 x 14.56 x 7.23 mm, cut to maximize symmetry and light return. The asscher cut gives this ametrine a timeless, architectural elegance, the stepped facets producing a hall of mirrors effect that makes the two distinct colors read as one composed work of art. The stone is eye clean when evaluated at eye level, with a medium intense color intensity that straddles vibrant and wearable, and an excellent polish that lets light travel freely through the pavilion and crown. Enhanced by heat treatment, and sourced from the classic ametrine deposits of Bolivia, this stone carries both natural origin and the careful treatments that gem connoisseurs expect for a look that is vivid and stable.

You may be picturing this stone set as the focal point of a bespoke engagement ring, or as a pendant that catches the first morning light on important days. The asscher octagon shape is particularly well suited to designs that emphasize clarity and geometry, so whether you prefer a minimalist bezel that shows off the facets, or an elegant four prong cathedral that allows light to enter from every angle, this ametrine will perform. The bi color nature of ametrine gives you two palette options in one gem, a regal purple meeting a warm golden yellow, and the precise asscher cut separates those color zones into planes that shift as the stone moves. At 11.05 carats and with the generous dimensions of 15.26 x 14.56 x 7.23 mm, the stone has a presence that reads as significant without overpowering. Because it is transparent and eye clean, jewelers can design settings that utilize the internal reflections and symmetry of the cut without concern for visible inclusions detracting from the field of color.

Owning this ametrine from Bolivia is an investment in beauty and craftsmanship, not merely in a durable object. The gemological story begins in one of the world regions best known for naturally occurring color zoning that produces ametrine, and continues through the hands of master cutters who chose an asscher faceting pattern to honor the stones natural dichotomy. Heat treatment has been applied to stabilize and bring out the medium intense color intensity, a standard enhancement that respects the integrity of the gem while delivering a consistent and lively palette. The finished polish is excellent, a detail that matters every time light meets the crown or when the stone is set into metal. For collectors, this gem represents rarity by virtue of its size, its precise cut, and its clearly defined bi color separation. For couples choosing a ring, the stone offers a singular symbol, its two colors reflecting partnership and balance. In both contexts the purchase is an investment in workmanship, provenance, and a piece that will age gracefully in the narrative of a family or a collection.
