1.65 Ct. Green Sapphire from Montana

One transparent 1.65 carat oval shape green sapphire, measuring 7.71 by 6.60 by 3.96 mm, presents a balanced combination of weight and spread, with a face up that communicates clarity and color evenly, The Natural Sapphire Company confirms origin as Montana, enhancement as none, and a clarity grade recorded as very slightly included when evaluated at eye level, The stone exhibits medium color intensity and an excellent polish, and the mixed brilliant cut is a central feature in how this sapphire interacts with light, delivering both broad flashes of brightness and a lively pattern of small, focused scintillation.

The mixed brilliant cut employed on this oval integrates a faceted crown based on brilliant geometry with a pavilion that blends step and brilliant elements, this hybrid approach allows the table to act as a window for color, while the pavilion facets act as mirrors to return light to the viewer, carefully proportioned crown height and pavilion depth promote optimal internal reflection, symmetry of facet placement and precision at the girdle control the path of incoming light, ensuring that light is refracted and reflected in a manner that enhances perceived brightness and color saturation, the result is an interplay between brilliance and fire that accentuates the sapphire s cool green tone without overpowering its medium intensity.

Clarity and polish contribute directly to optical performance, the grade of very slightly included at eye level indicates that inclusions are minor and do not materially obstruct light transmission, these small natural features can sometimes aid scintillation by breaking up larger planes of reflection into smaller, lively flashes, however the excellent polish and careful facet junctions minimize light leakage, enabling the mixed brilliant layout to produce well defined contrast patterns, the oval outline further influences light behavior by elongating the light path in two axes, this elongation increases apparent size as viewed face up, while maintaining concentrated return of light to the crown and preserving a pleasing balance between depth and table area.

Practical considerations for setting and presentation follow from the cutting geometry, with dimensions of 7.71 by 6.60 by 3.96 mm the gem is well suited to classic ring proportions as well as pendant settings that allow light to enter from multiple angles, an elevated open setting will maximize the pavilion s ability to return light, while a bezel that leaves the crown exposed will protect the girdle without significantly diminishing brilliance, the mixed brilliant cut also adapts well to design directions that favor both sparkle and color consistency, the Montana origin often yields a nuanced green with subtle open tones, and the cut has been executed to preserve that regional character, maximizing the stone s natural appeal while avoiding artificial enhancement.

This Montana green sapphire embodies a considered approach to cutting that privileges controlled light reflection and truthful color expression, The Natural Sapphire Company presents the gem with clear documentation of origin, enhancement status, and clarity grading, the mixed brilliant cut amplifies the inherent optical qualities by channeling light through a well balanced crown and pavilion relationship, by maintaining excellent polish and precise facet symmetry the cutter ensured that each facet contributes to a cohesive optical performance, the stone s medium color intensity, transparent body, and modest inclusions combine with cutting excellence to deliver a sapphire whose interaction with light is both technically refined and visually engaging.
