1.19 Ct. Bluish Green Sapphire from Montana

This transparent 1.19 carat oval bluish green sapphire presents a well documented combination of natural character and precise lapidary execution. The stone measures 6.41 x 5.03 x 4.45 mm, and its oval outline has been proportioned to maximize both hand presence and optical performance. Origin is Montana, and the piece is untreated, no enhancement, which means the color and clarity you see are entirely natural. At The Natural Sapphire Company we prioritize provenance and transparency, and this sapphire’s Montana origin is consistent with a profile of lively, cool to slightly warm bluish green hues that are stable without heat or diffusive treatments. The piece carries a clarity grade of very very slightly included as evaluated at eye level, which in practical terms reads as eye clean with only minute features detectable under careful close inspection.

The cutting style is a mixed brilliant cut, executed to combine the scintillation and dispersion traits of a brilliant faceting scheme with the color control and land management of step related facets. The crown presents a modified brilliant arrangement that favors a slightly larger table to increase apparent size while maintaining facet junction integrity. The pavilion employs a combination of brilliant and modified facets to direct light back through the crown, producing lively white flashes and controlled color return across the oval plane. The stone’s depth of 4.45 mm relative to its average dimension of 5.72 mm yields a depth proportion of approximately 77.7 percent, which is on the deeper side for oval shapes. That depth gives more material in the girdle to intensify the medium intense color, and the cutter has balanced pavilion angles to avoid excessive windowing or dead zones, preserving sparkle while enhancing saturation. Craftsmanship is evident in the excellent polish and well formed facet junctions, which produce crisp reflections and minimal surface polish lines.

Color and clarity interplay is a central technical advantage of this sapphire. The hue reads bluish green with a medium intense color intensity, a level of saturation that avoids both a washed look and an opaque blockiness. The medium intensity allows the bluish and green components to remain distinct under varied lighting, while the mixed brilliant faceting disperses light in a way that distributes color evenly across the table and along the shoulders of the oval. Clarity graded as very very slightly included evaluated at eye level indicates that inclusions are extremely minor, and that the visual field is clean to the unaided eye for practical use in fine jewelry. Inclusions of this class typically do not interrupt light pathways significantly, and because the piece is untreated, they are natural formation features rather than treatment residues. The excellent polish is a sign of optimal lapidary finishing, reducing surface scattering and allowing internal facet planes to remain the dominant contributors to brilliance and color. For collectors and connoisseurs who assess sapphires by hue nuance, tone control, and facet junction precision, this Montana stone offers a finely balanced technical package.

Durability and suitability for everyday wear are essential considerations for high quality sapphires, and this specimen performs exceptionally in that regard due to corundum’s position on the Mohs scale. Sapphire is a nine on the Mohs hardness scale, making it second only to diamond which registers ten, and substantially harder than common jewelry materials such as quartz which registers seven. In practical terms the Mohs nine rating means that the sapphire resists scratches from almost all materials you are likely to encounter in daily wear except for diamond and other corundum with abrasive contact under severe conditions. The stone’s excellent polish and compact oval dimensions further reduce susceptibility to chipping because facet edges are robust and the girdle area is ample relative to overall size. Nevertheless careful setting and occasional maintenance are recommended. We typically advise settings that provide protective prong shoulders or a partial bezel for customers engaged in active lifestyles, and routine inspection of prongs to ensure that the sapphire remains secure. At The Natural Sapphire Company we can recommend specific mounting options that preserve the stone’s optical attributes while optimizing protection, and we can supply photographic documentation and independent assessment reports upon request.

If your priority is a transparent, natural, high polish Montana sapphire that combines a mixed brilliant cut with a medium intense bluish green hue and very very slightly included clarity as evaluated at eye level, this 1.19 carat oval is a technically accomplished choice. The combination of a deeper cutting proportion with carefully controlled pavilion and crown angles delivers concentrated color without sacrificing brilliance, and the no enhancement provenance preserves natural value and character. For buyers focused on technical characteristics we can provide additional measurements, facet maps, and viewing images to illustrate facet symmetry, table size, and the distribution of light return. Our team at The Natural Sapphire Company is available to discuss setting options that complement the stone’s depth and mixed brilliant faceting, to ensure that the finished piece meets both aesthetic and durability expectations.
