Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 9mm round diamond, poised to become the heart of a three-stone engagement ring. This semi-set foundation in warm 10K yellow gold offers a handcrafted canvas for your chosen center stone, designed with precision in our Williamsburg studio.

The band’s smooth, low-profile silhouette balances artisan finish with everyday wearability, its subtle weight resting comfortably against the skin. Each prong is carefully shaped to cradle the stone securely while allowing light to dance freely, enhancing brilliance without bulk.

Crafted from responsibly sourced 10K yellow gold, this mounting embraces the clarity and sustainability of lab-grown diamonds, reflecting a commitment to ethical jewelry without compromise.

Ideal for those who appreciate classic geometry with a modern twist, the three-stone setting complements a variety of hand sizes and shapes, offering versatility for stacking or solo wear. Its modest height ensures glove-friendly ease and daily comfort.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a perfect fit without disrupting the ring’s refined lines.
