Morganite and Diamond Engagement Ring in 18K Gold and Platinum

Oval Blue Montana Sapphire and Diamond Ring in 14K White Gold

A rare and deeply personal gemstone, this oval blue Montana sapphire ring is designed with refined elegance, luminous contrast, and the kind of quiet confidence that only a truly meaningful stone can carry.

At its center sits a natural blue Montana sapphire weighing approximately 1.47 carats, sourced from the storied gem deposits of the American West. Framed by a delicate halo of natural round diamonds totaling approximately 0.30 carats and accented by additional diamond side stones, the ring creates a layered brilliance that enhances the sapphire's natural depth without overpowering its beauty.

Crafted in 14K white gold, the cool tone of the metal complements the blue of the sapphire beautifully, creating a design that feels both luminous and grounded.

A rare American gemstone ring with collector character and timeless refinement.

About This Gemstone

Montana sapphires are among the rarest and most distinctive sapphires in the world, sourced from a small number of deposits in the American West — primarily the Yogo Gulch and alluvial fields of western Montana. Unlike Ceylon or Kashmir sapphires, Montana stones carry a uniquely American character: often appearing in distinctive steel blue, teal, or parti-color tones that reflect the mineral-rich geology of their origin. Their rarity and domestic provenance have made them increasingly sought after by collectors and jewelry designers worldwide.

Perfect For

• A collector-quality engagement or statement ring
• Those drawn to rare and regionally significant gemstones
• A meaningful modern heirloom with American provenance
• Lovers of unique sapphire color and natural character

Made to order with intention.
