Custom Round Teal Australian Sapphire Engagement Ring in 14K Yellow Gold

This custom engagement ring features a striking round brilliant–cut teal sapphire, ethically sourced from Australia and set in warm 14K yellow gold. Weighing 1.09 carats and measuring 6.37 × 6.33mm, the natural sapphire displays a rich blend of blue and green tones that shift beautifully with the light.

The center stone is elevated in a refined gold setting with sculptural lines that add elegance and strength without overwhelming the sapphire. From the side, subtle architectural details create visual interest and give the ring a graceful profile, while keeping the overall design clean and timeless.

The contrast between the vivid teal sapphire and yellow gold gives this ring a classic yet distinctive character—perfect for someone drawn to color, craftsmanship, and understated originality.

Designed as a bespoke piece, this ring highlights:

• Round brilliant–cut natural Australian teal sapphire (1.09 ct)
• 14K yellow gold setting that enhances warmth and color contrast
• Clean, sculptural prong work with elegant side detailing
• A balanced, timeless silhouette with a modern edge
• A fully custom design created around a one-of-a-kind natural stone

This ring is a beautiful example of how custom design at Rustic & Main allows exceptional natural gemstones to take center stage, supported by thoughtful craftsmanship and intentional detail.
