Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated silhouette of a marquise diamond, it casts a subtle, graceful sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring in warm 18K rose gold offers a refined foundation for a 7 x 3.5 mm marquise center stone, ready to be chosen to your exact preference.

The band is crafted with a low-profile setting that hugs the finger comfortably, designed for daily wear without catching or shifting. Its smooth finish and precise prong placement ensure the stone sits securely while maintaining an elegant, streamlined look. The rose gold’s soft blush tone complements the marquise’s dramatic shape, enhancing its vintage-inspired allure with modern durability.

Each lab-grown diamond option reflects a commitment to ethical sourcing and environmental mindfulness, offering clarity and brilliance without compromise. This ring’s design balances statement and subtlety, ideal for those who appreciate a sleek silhouette that layers well with other bands or stands strikingly alone.

Its comfort fit band suits a variety of hand sizes, and the semi-set format invites personal choice in diamond selection, allowing you to tailor the sparkle to your vision. Resizing is available to ensure a perfect fit, crafted with care in our Williamsburg studio.
