Custom Pear-Cut Blue Sapphire Three-Stone Engagement Ring in 14K Yellow Gold

This custom engagement ring features an 8x5mm pear-cut lab-grown blue sapphire, weighing approximately 1.06ct, set in warm 14K yellow gold and flanked by brilliant lab-grown diamond accents in a timeless three-stone arrangement. The rich blue center stone offers striking depth and clarity, creating beautiful contrast against the golden setting.

Inspired by our Diana design, this ring highlights how a thoughtful material change can dramatically shift the character of a piece. By choosing yellow gold in place of the original white gold, the sapphire takes on added warmth and presence, lending the ring a more classic, heirloom-inspired feel while maintaining the elegance of the original design.

The pear-shaped lab-grown sapphire is balanced by two lab-grown diamond side stones that enhance its brilliance and emphasize its graceful silhouette. Clean prong work and a refined band keep the focus on the stones themselves, allowing the color and proportions to speak with confidence and restraint.

Designed as a bespoke piece, this ring highlights:

• 8x5mm pear-cut lab-grown blue sapphire, approximately 1.06ct, with rich, saturated color
• 14K yellow gold setting for a warm, timeless aesthetic
• Three-stone design with lab-grown diamond accents for balance and sparkle
• A custom reinterpretation of the Diana design through metal choice
• A classic, enduring silhouette that feels refined and personal

This ring is a beautiful example of how customization at Rustic & Main often comes down to intentional choices, using trusted designs as a foundation while tailoring materials to tell a different story.

If this style inspires you, we'd be honored to create your own custom version of the Diana, or help design a ring inspired by this piece, crafted around your preferred stone, metal, and personal details.
