1.35 Ct. Greenish Blue Sapphire from Montana

This exquisite greenish blue sapphire from Montana is an exceptional find offered by The Natural Sapphire Company, a gem for collectors and connoisseurs who demand rarity and provenance. Weighing 1.35 carats, this round shape gem measures 6.84 by 6.81 by 4.26 millimeters, and it has been masterfully fashioned with a mixed brilliant cut to maximize its optical performance. Its transparency is remarkable for a natural Montana stone, and at eye level it is graded very slightly included, a clarity that allows vibrant light return while retaining natural character. The color intensity is classified as medium intense, a tone that balances presence and subtlety, and every facet benefits from an excellent polish, ensuring crisp reflections and a refined surface. Importantly this sapphire has no enhancement, making it a rare untreated example from Montana, and an opportunity to own a pure, natural treasure from a storied American source.

What distinguishes this Montana sapphire in visual performance is the way it handles light, a quality that becomes obvious when compared to other sapphires in its category. The mixed brilliant cut creates a dynamic interplay of large crown facets and a well proportioned pavilion, producing lively scintillation that dances across the table and crown. Compared to traditional step cut or shallow cuts sometimes seen in regional stones, this cutting style returns more lively sparkle, and the excellent polish preserves crisp facet junctions that amplify brilliance. Against classic Sri Lankan sapphires that often present a brighter, lighter blue with higher apparent luster, this Montana gem shows a cooler, greenish blue character with a slightly deeper tonal presence. Against Kashmir and certain untreated high saturation blues, which often show velvety depth and diffuse glow, this sapphire offers sharper facet contrast and more lively pinpoint scintillation. The combination of eye level clarity and a mixed brilliant architecture means that light penetrates deeply and reflects with clarity, creating a lively, multifaceted brilliance that is distinctive within the spectrum of blue and greenish blue natural sapphires.

In practical wear and design, the reflective qualities of this sapphire lend it a versatile presence that adapts beautifully to bespoke settings and personal style. Because sapphires have a refractive index that favors bright return without the dispersion or fire of diamond, the strength of this gem lies in its color and scintillation rather than spectral flashes. Against paler stones such as aquamarine, or bluish tourmaline, this Montana sapphire appears richer and more saturated, and it returns light with more intense flashes due to its cutting and polish. Compared to highly included or heavily heat treated sapphires, this untreated stone carries a transparency and natural hue that exhibit color complexity when viewed from different angles, shifting between green and blue tones under varied light. On the finger it reads as an elegant statement, lively under gallery lights, and quietly majestic in daylight, and it pairs especially well with cool metal tones, though it can be contrasted beautifully by warm gold for a bespoke, modern look.
