0.89 Ct. Green Sapphire from Montana

This listing describes one transparent green sapphire of 0.89 carat, presented in a cushion shape with exact dimensions of 5.20 x 5.20 x 3.75 millimeters, cut in a mixed brilliant style, and originating from Montana. The gem exhibits medium color intensity, with a clear, cool green tone and subtle blue undertones that can appear more or less pronounced depending on light angle and setting. The clarity has been graded as very slightly included, evaluated at eye level, and the stone displays an excellent polish that enhances light return. The sapphire has been heat treated, a common and stable enhancement that improves color uniformity and overall appearance, and the combination of its transparency and quality cut produces consistent brilliance across the table and crown facets. The Natural Sapphire Company is the source for this piece, and the description above reflects the gem as viewed and graded by our specialists.

The mixed brilliant cut is responsible for the gem’s lively scintillation, pairing larger brilliant style facets on the pavilion with more angular crown faceting that scatters light while maintaining a balanced face up appearance. Viewed face up the stone presents a well distributed color and a pleasing balance of sparkle and color saturation, while the pavilion depth of approximately seventy two percent contributes to strong light return without excessive windowing. The excellent polish ensures crisp facet junctions and minimal surface disturbance, which allows the very slightly included clarity to remain unobtrusive, with inclusions discernible only under close inspection and not distracting from the gem’s overall transparency or brightness. These optical and finish characteristics make the gem versatile for a variety of designs where both color and sparkle are desired.

In terms of setting and wearability, this Montana green sapphire benefits from the intrinsic durability of sapphire, which rates nine on the Mohs scale, making it suitable for everyday jewelry when set appropriately. For rings, a secure prong setting that protects the corners of the cushion profile is recommended, or a low bezel interpretation for a more protective and modern aesthetic. For pendants or earrings, the stone’s modest size and balanced proportions work well in solitaire mounts or as the focal point among small accent stones, where the excellent polish and mixed cut will contribute to observable scintillation in motion. Metal choice will influence perceived color, with white metals such as platinum and white gold lending a crisp, cooler backdrop that highlights the green blue nuances, while yellow or rose gold will warm the overall appearance, softening the green toward olive and enhancing a vintage or romantic expression.

When considering complementary gemstones for a custom piece, several approaches will accentuate different aspects of this Montana sapphire. For maximum contrast and classic refinement, a halo or shoulder set of white diamonds will amplify brilliance and make the sapphire’s medium green tone read more vivid. For a tonal, sophisticated design, pairing the center stone with small green tourmalines or slightly deeper green sapphires will sustain a monochromatic palette, creating a considered, understated look. If a warm contrast is preferred, small yellow sapphires or cognac colored diamonds will introduce warmth, making the green appear fresher by comparison. Three stone configurations with tapered baguette diamonds can lend architectural balance, while clusters of old mine cut diamonds around the cushion shape will produce a vintage character and soft, scintillating contrast. For seasonal or softer palettes, small morganites can add a peach wash that plays off the cool green, though attention to relative durability and placement is recommended for pieces intended for daily wear.

This Montana green sapphire, as presented by The Natural Sapphire Company, offers a combination of measured carat weight, precise cushion proportions, and carefully executed cutting and polishing that make it an excellent candidate for bespoke jewelry projects. The stone’s origin, clarity grade, and heat treated enhancement are summarized clearly so that designers and clients can make informed decisions about setting, metal, and companion stones. Whether used as a standalone solitaire, the center of a refined three stone ring, or as the focal point within a halo or cluster, the gem’s transparent nature and mixed brilliant cut provide visual interest and reliable performance.
