Antique Style Greenish Blue Sapphire Ring 0.67 Ct., 18K White Gold

This ring centers on a transparent 0.67 carat oval shape greenish blue sapphire, measuring 6.52 by 4.13 by 3.07 millimeters, cut as a mixed brilliant to balance internal fire and surface brilliance, clarity graded as very slightly included when evaluated at eye level, color showing medium saturation, and an excellent polish that enhances light return. The sapphire originates from Montana, a source known for distinct and often subtle bluish green tones, and is set in a fully 14K white gold mounting that provides a cool, reflective backdrop to the stone. The setting has been crafted to present the oval profile with balanced proportion, secure prong support, and a refined band profile, combining durability with a slender visual appearance that allows the sapphire to remain the primary focus.

The design of this ring is highly adaptable to create a one of a kind piece personalized for the wearer. Metal selection can be altered to 18K white gold, platinum, 14K or 18K yellow gold, or rose gold to subtly shift how the sapphire color reads on the finger, with warmer metals emphasizing the greenish notes and cooler metals bringing out the blue. The setting can be modified from the current prong presentation to a low bezel for added protection, a halo of small diamonds or colored sapphires for increased visual impact, or a split shoulder or cathedral gallery for an elevated profile and architectural detail. Accent stone choices include melee diamonds for contrast, near colorless sapphires for a tonal palette, or fancy colored diamonds for a distinct look. Band treatments are available including engraved patterns, milgrain, matte or brushed finishes, hand hammered texture, and internal engraving for a personal message. Ring width, finger size, and prong count are adjustable to balance comfort and security, and we can provide CAD renderings and photographic samples prior to production. All custom pieces are completed with careful attention to the integrity of the sapphire, preserving its polish and minimizing unnecessary heat or mechanical stress during setting. For clients seeking a bespoke creation, The Natural Sapphire Company offers individualized consultation, detailed design options, and documentation of the stone and finished piece, enabling a tailored, singular ring that reflects both the gem characteristics and the wearer’s intentions.
