2.30 Ct. Bluish Green Sapphire from Montana

As a gemstone specialist at The Natural Sapphire Company, I am pleased to present a transparent 2.30 carat cushion shape bluish green sapphire, measuring 8.56 by 6.97 by 4.35 mm. The mixed brilliant cut and excellent polish give this gem a lively play of light, while the medium color intensity creates a serene bluish green that is both distinctive and versatile. Evaluated at eye level, the clarity grade is slightly included, which means the stone retains excellent transparency and sparkle to the naked eye, yet carries tiny natural characteristics that confirm its natural origin. The sapphire is from Montana and has no enhancement, a feature that places it ahead of many market options that rely on heat treatments or other enhancements to intensify color. Compared with the many heat treated commercial sapphires that dominate the market, this untreated Montana stone offers a purity of origin and an authentic character that collectors and discerning clients will value. In practice, the combination of transparency, moderate color depth, and untouched provenance creates a gem that looks elegant under jewelry lighting, while offering long term desirability that outperforms many mass market alternatives.

The cushion shape itself is one of the most adaptable shapes for custom work, and this particular example is especially well suited to bespoke designs. Its softened square silhouette blends classic and contemporary aesthetics, offering clean lines for bezel and halo settings, while the generous corners provide secure prong placement that complements rather than competes with the stone. The mixed brilliant cut brings modern light performance into the traditional cushion outline, producing lively scintillation that reads well in both natural and indoor light. At 8.56 by 6.97 mm and 2.30 carat weight, this sapphire sits comfortably in designs that range from solitaire engagement rings to statement pendants and cocktail rings, while the 4.35 mm depth balances face up presence with structural integrity. Compared with elongated ovals that may require taller galleries or unusual mounting techniques, and versus extremely deep cuts that mandate higher settings, this cushion is easy for bench jewelers to work with, which can reduce fabrication complexity and cost. The slightly included clarity is an advantage for custom jewelers because the minor natural features help validate the gem as natural and untreated, and they reduce the risk of overworking during any further cutting or setting adjustments.

When considering value and uniqueness, this Montana sapphire stands out for natural origin, no enhancement, and balanced dimensions that make it a superb choice for custom commissions. Many stones on the market are altered to achieve uniform color, or they come from sources where treatment is common, which can affect both long term market value and personal preference for natural character. This sapphire, offered untreated, is therefore superior in provenance and particularly appealing to those who prioritize authenticity. The medium color intensity ensures the gem wears beautifully against both white and warm metals, while the bluish green hue provides a fresh alternative to classic blue sapphires without sacrificing sophistication. Compared with lab created alternatives, a natural untreated sapphire retains a geological story and individuality that cannot be replicated. At The Natural Sapphire Company our gemologists and designers specialize in matching exceptional stones to bespoke settings, advising on metal choice, diamond accents, and mounting style to highlight a stone like this. Whether the design brief calls for a vintage halo, a minimalist bezel for everyday wear, or a dramatic solitaire that showcases the cushion silhouette, this 2.30 carat Montana sapphire is sized and proportioned to simplify the custom process and to deliver enduring beauty.
