4.88 Ct. Greenish Blue Sapphire from Montana

This transparent 4.88 carat oval greenish blue sapphire from Montana presents dimensions of 10.98 by 8.99 by 6.29 mm, a mixed brilliant cut, and excellent polish. Unlike heavily treated sapphires that dominate the market, this gem is natural with no enhancement, making it rarer and more stable for custom jewelry. The light color intensity and the subtle greenish blue hue set it apart from more saturated stones, offering a versatile tone that complements both warm and cool metals. Compared with smaller stones, the near five carat weight gives immediate presence, while the classic oval outline provides a flattering footprint that works beautifully in rings, pendants, and statement earrings. The slightly included clarity, evaluated at eye level, gives the stone character and a natural fingerprint, without compromising transparency, and it also allows for more competitive pricing than flawless alternatives, making it an excellent value choice when you want a substantial authentic sapphire rather than a heavily treated substitute.

For custom designers and discerning buyers the combination of these attributes makes this Montana sapphire a superior choice. The mixed brilliant cut balances table sparkle and pavilion depth, creating lively brilliance under varied lighting, and the 10.98 by 8.99 mm face up size fits standard oval settings for an easier mounting process. Compared to perfectly clear but commonly treated stones from other sources, this gem offers uniqueness, provenance, and the story of an American origin. At The Natural Sapphire Company we find that clients prefer unenhanced material for heirloom pieces and bespoke commissions, because it holds its identity and age gracefully. Whether you are planning a solitaire engagement ring with a low profile east west setting, a halo design that amplifies color, or a custom pendant that showcases the stone against satin finished metal, this sapphire provides a reliable balance of size, shape, and natural charm that streamlines design decisions while delivering rare authenticity.
