Description

Octagon Montana Sapphire Ring | Solid Gold (Size 7)

If you’re looking for a ring that blends ancient history with a bold, geometric aesthetic, this Octagon Montana Sapphire Ring is a standout. Forged deep within the earth 150 to 200 million years ago under the big skies of Montana, this ethically mined stone is completely untreated—exactly as formed by the earth. Hand-fabricated entirely in 14k solid gold, the warm setting elevates the balanced, architectural feel of the cut-corner square cut.

The octagon silhouette offers a sophisticated, vintage-meets-modern look, displaying a deep blue hue accented by signature teal undertones. Enclosed securely within a polished 14k solid gold bezel setting, the smooth gold frame protects the stone's angular edges for a flush, snag-free profile designed for effortless daily wear.

  • The Stone: Hand-selected 0.76 carat cut-corner square (octagon) Montana sapphire displaying rich blue hues with vibrant teal undertones (ethically mined, USA origin, untreated).

  • The Craft: Hand-fabricated 14k solid gold bezel, backplate, and hand-forged band.

  • The Fit: Current size 7 (Can be resized up or down up to 2 sizes. Please note your desired size at checkout).

  • The Vibe: Bold, architectural, and timelessly unique.

  • Why We Love It: The sharp, clean lines of an octagon cut paired with a full 14k solid gold bezel setting create a deliberate, heirloom-quality presence. The low-profile structure makes it comfortable enough for daily wear while securing a rare piece of American geologic history.

Care Tip from the Studio: To preserve your sapphire’s brilliance and maintain the warm glow of the solid 14k gold, we recommend gentle cleaning with warm, soapy water and a soft-bristled brush every few weeks. This removes daily oils so those geometric facets pop every time the light catches the stone.
