1.26 Ct. Bi Color Sapphire from Montana

This transparent bi color sapphire presents a precise combination of measurements and optical quality, and it is offered by The Natural Sapphire Company. The stone weighs 1.26 carats and is fashioned in an elegant oval shape with dimensions of 6.47 by 5.69 by 4.17 millimeters. The cut is a mixed brilliant style, a choice that balances the pavilion and crown facets to enhance both brilliance and color. Clarity is graded as very very slightly included when evaluated at eye level, and the surface polish is excellent, minimizing light diffusion at the facet junctions. The color intensity is described as intense, and the bi color character is evident in the images and in hand, presenting lively transitions that respond to viewing angle. The sapphire is heat treated, a standard and stable enhancement method, and the documented origin is Montana, a region known for sapphires with unique and often earthy tones. These specifications provide a clear technical foundation for understanding how the cut and finish interact with the material properties to produce the gem s visual behavior.

The mixed brilliant cut of this oval sapphire is fundamental to its light performance, because the combination of faceting styles controls both light return and color distribution. The crown facets are arranged to refract incoming light into the pavilion, while the pavilion facets are arranged to reflect that light back through the crown, creating a balance of brilliance and depth. The table is sized to allow a substantial window for light entry without overwhelming the faceting pattern, and the layered pavilion facets create a cascade of internal reflections that produce scintillation as the stone moves. Because the cut incorporates both step and brilliant elements, it moderates strong light dispersion while preserving the lively flashes that define a brilliant cut, and it yields a controlled play of light that is particularly effective in bi color material. The excellent polish ensures that facet planes act as clean mirrors, reducing light scattering at the surface and preserving crisp contrasts between bright flashes and darker facet areas, and precise symmetry aligns the optical axes so that light paths are predictable and repeatable from multiple viewing angles.

Proportions of this sapphire contribute directly to its optical character, and a simple analysis of dimensions clarifies how the geometry influences light behavior. The average diameter of the oval, calculated from the length and width, is approximately 6.08 millimeters, and the depth of 4.17 millimeters corresponds to a depth percent of approximately sixty eight point six percent, a proportion that tends to concentrate light return toward the crown and intensify apparent color saturation. In practical terms, a slightly deeper pavilion can reduce leakage of light through the girdle and instead direct more photons back to the observer, which enhances perceived richness in a gem with intense color. In a bi color sapphire this effect intensifies the separation of color zones as well as the blending that occurs in movement, so the viewer experiences both distinct color flashes and a cohesive overall hue. The very very slightly included clarity means that inclusions are minimal at eye level and generally do not interrupt the principal light paths, allowing the cut to perform without significant obstruction, and the heat treatment is uniform and stable, optimizing color while preserving transparency and structural integrity.

Taken together, these attributes describe a gemstone whose cut amplifies its inherent optical strengths, and the result is a sapphire that communicates both presence and subtlety. The mixed brilliant faceting produces a lively interplay of brilliance and glow, the oval outline introduces a soft elongation that guides the eye across shifting color zones, and the careful polishing and proportioning reduce light loss and maintain crisp facet definition. The natural hardness and durability of sapphire support a variety of mounting choices, and the stone s characteristics make it appropriate for settings where movement and light exposure will reveal the bi color dynamics. For professionals assessing the gem for design or for clients seeking a technically articulate description, the combination of a 1.26 carat weight, an oval shape at 6.47 by 5.69 by 4.17 millimeters, mixed brilliant cut, very very slightly included clarity at eye level, intense color intensity, excellent polish, heat treatment, and Montana origin defines a stone with reliable optical behavior and distinct character. The Natural Sapphire Company documents these attributes to provide a transparent and factual foundation for evaluation and design.
