1.35 Ct. Bluish Green Sapphire from Montana

This transparent 1.35 carat cushion shape bluish green sapphire, measuring 6.18 by 6.16 by 4.33 millimeters, is a compelling choice for anyone seeking a stone that balances depth of color with refined cut and polish. Cut as a faceted mixed brilliant and finished with an excellent polish, this gem delivers lively internal reflections while maintaining the rich, dark color intensity that makes Montana sapphires distinct. Evaluated as very slightly included at eye level, the clarity is strong for practical wear, and the heat treatment applied is a stable, widely accepted enhancement that refines tone without sacrificing the natural character of the stone. Compared to many commercial sapphires on the market that favor overly bright, sometimes synthetic-looking blues, this bluish green Montana sapphire offers a more nuanced, sophisticated palette, a unique personality that reads as both natural and upscale, and a depth of color that performs beautifully under varied lighting conditions.

When you think about customizing this cushion sapphire into jewelry, its proportions and cut make it extraordinarily versatile. The classic cushion outline works equally well in traditional four or six prong solitaires that let the mixed brilliant facets breathe, and in bezel settings that emphasize durability for daily wear. For a piece that maximizes perceived size and sparkle, a diamond halo will lift the stone visually and bring contrast that brightens the bluish green, while a thin pavé split shank or hidden halo can add modern brilliance without overwhelming the sapphire. East-west orientations suit contemporary bezel and tension rings, while vintage inspired mountings, filigree, and milgrain detailing pair beautifully with the cushion shape to create heirloom-quality pieces. The stone’s relatively compact depth and strong table face mean it sits well in low profile settings for comfortable everyday rings, yet with a slightly raised cathedral or open gallery it can be shown off to better effect during formal occasions.

Beyond rings, this sapphire adapts to a wide array of jewelry formats. A solitary pendant allows the stone’s color shifting characteristics to be appreciated against the skin, and pairing it with warm yellow or rose gold metals will naturally accentuate the green components, creating a rich, organic look that stands apart from conventional blue sapphires. Platinum or white gold mountings emphasize the cooler blue tones and work superbly with accompanying diamonds for a classic, high-contrast aesthetic. For earrings, although this single stone is singular, it suggests a matched pair of similar Montana stones for stud or drop designs, or it can be the focal stone in a mismatched, fashion-forward set where one piece is intentionally unique. Men’s jewelry is another excellent application; the cushion cut lends itself to signet and bezel-set rings that are both masculine and refined, and the stone’s dark intensity hides wear well while retaining polished sophistication. Consider combining this sapphire with accent gems such as small green tsavorites for tonal harmony, or warm champagne diamonds to add glow, depending on whether you want the final piece to read modern, vintage, or eclectic.

Choosing this Montana sapphire through The Natural Sapphire Company gives you both provenance and personalization that many mass-market options cannot match. Montana sapphires are prized for their earthy, artisan character and range of blue-green tones that are increasingly sought after by customers who want authenticity over uniformity. Compared to imported sapphires that are treated heavily or altered to fit a narrow color standard, this gem’s heat treatment is disclosed and minimal, preserving the natural charm that makes it special. Our custom design services can provide CAD renderings, setting recommendations tailored to the stone’s 6.18 by 6.16 by 4.33 millimeter dimensions, and metal and accent suggestions based on your lifestyle and budget. We support custom ring seats, prong placements that protect the girdle, and options like low profile bezels for active wearers or raised settings for maximum presence. If you want to explore a one-of-a-kind engagement ring, a pendant that will spark conversation, tailored earrings, or a unique men’s piece, we can craft multiple mockups and advise on how to achieve the best balance of light performance, security, and style.
