1.44 Ct. Bi Color Sapphire from Montana

This is a finely presented, transparent 1.44 carat cushion shaped bi color sapphire, sourced from Montana and offered by The Natural Sapphire Company, with dimensions of 7.11 by 6.03 by 4.34 millimeters. The stone is fashioned with a mixed brilliant cut which combines facets designed to maximize both face up brilliance and internal scintillation, and it has an excellent polish that enhances surface luster and clarity to the eye. The gem displays intense color intensity, a distinct bi color character with visually different hues across the stone when viewed from different angles, and a clarity described as very very slightly included when evaluated at eye level, which means that inclusions are minimal and do not materially interfere with light return or the gem's attractive appearance. The stone has been heat treated, a common and accepted enhancement in sapphires that improves color saturation and overall stability, and the proportions yield a depth of 4.34 millimeters which corresponds to a depth percentage of approximately 66 percent based on the average of the length and width, a proportion that supports good light performance in a cushion outline.

From a connoisseur perspective the clarity grade and excellent polish are important practical points. Very very slightly included at eye level places this sapphire in a range where the stone reads clean to most viewers without the premium pricing of completely eye clean material, while still retaining natural characteristics that are typical of quality Montana sapphires. The mixed brilliant cut is intentionally chosen for colored material like this bi color sapphire, because it increases facet interactions and creates a lively pattern of bright flashes and darker contrast zones that emphasize the bi color effect. The excellent polish ensures that surface reflections are crisp and that light enters and exits the stone with minimal scattering from the surface, which is particularly important for a gem with intense color where surface quality directly affects perceived saturation and depth. The dimensions and weight combine to make this gem suitable for a broad range of jewelry settings, and the balanced depth percentage helps to maintain strong face up presence without losing weight to an overly deep pavilion.

When comparing reflective qualities to other gemstones within its category this Montana bi color sapphire performs differently than single tone blue sapphires and differently still from gemstones such as spinel, garnet, and diamond. Compared with classic single tone blue sapphires, which are often judged on uniformity and depth of color, a bi color sapphire introduces dynamic visual interest through color zoning and pleochroic behavior, so the viewer experiences changes in hue and tone as the gem moves, with mixed brilliant facets amplifying that movement through scintillation. Compared with step cut or more gently faceted colored stones, the mixed brilliant cut here produces greater scintillation and a livelier play of light, while step cuts tend to emphasize color and clarity with broader flashes rather than numerous small sparkles. In absolute optical terms sapphires have a lower refractive index and lower dispersion than diamond, so they will not show the same level of fire or spectral flashes, however a well cut sapphire with very good polish and intense color will appear richly luminous and may show stronger contrast and more nuanced color reflections than many other colored stones. Against spinel or garnet of similar tone, this sapphire typically shows stronger pleochroism and a more complex internal light pattern due to the mixed brilliant arrangement, and the bi color nature gives it an aesthetic that is both rare and collectible in the market for natural colored sapphires.

For an educated buyer considering this sapphire from The Natural Sapphire Company practical considerations include the origin and treatment history, the cutting style, and how the stone will be set to best display its attributes. Montana provenance is prized for producing sapphires with distinctive and often subtle secondary hues and for material that conveys an appealing natural character, and heat treatment in sapphire is a standard industry practice that stabilizes color while maintaining long term durability. The cushion shape and mixed brilliant cut lend themselves to settings that allow light to enter from multiple angles, so open prong settings or a minimally obstructive bezel can highlight the bi color shifts and maximize face up brilliance. Because the stone reads clear at eye level and has excellent polish, it will perform well as a center stone in rings or as a distinctive accent in bespoke designs, offering both everyday wearability and strong visual impact.
