1.16 Ct. Bi Color / Parti Sapphire from Montana

This 1.16 carat, transparent round bicolor parti sapphire presents as a refined specimen for a discerning collection. Measuring 6.12 x 6.15 x 4.13 mm, the stone is faceted in a mixed brilliant cut that balances light return and scintillation with a controlled pavilion depth. Color zoning manifests as a juxtaposition of warm amber and cooler greenish tones, producing a parti effect that is both distinct and harmonious under typical lighting. The gem is graded with intense color intensity and a clarity assessment of very slightly included at eye level, indicating minor natural characteristics that do not materially detract from its visual presence. The excellent polish and precise facet junctions contribute to crisp facet reflections and a polished overall presentation, suitable for examination in hand or mounted in fine jewelry.

Originating from Montana, this sapphire has undergone heat treatment, a standard and stable enhancement that improves color uniformity while preserving the stone structure and natural characteristics. The combination of its weight, symmetry, and mixed brilliant cutting style makes this piece particularly well suited as an addition to a high end gemstone collection, where collectors prioritize provenance, cutting quality, and distinctive color personality. The Natural Sapphire Company offers this sapphire as a cataloged example of American sourced parti sapphires, accompanying clear specifications for those assessing suitability for investment or bespoke design. For curators and jewelers seeking a compact yet visually engaging stone with verifiable origin and documented enhancement, this Montana bicolor parti sapphire represents a balanced option that aligns with high end collecting standards.
