Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set solitaire ring invites you to choose a center stone that will become a personal emblem of your story.

Crafted in warm 18K rose gold, the band curves gently with a low-profile setting designed for everyday grace and comfort. The smooth finish and subtle taper ensure it sits close to the finger, making it an ideal choice for stacking or wearing solo with ease.

Each ring is handcrafted in our Williamsburg studio, where precision meets thoughtful design. The rose gold’s soft blush complements the marquise’s distinctive shape, enhancing its vintage-inspired allure without overwhelming the stone’s natural brilliance.

Our commitment to sustainability is reflected in the option for a lab-grown diamond center—offering clarity and sparkle with a lighter environmental footprint.

This solitaire suits those who appreciate refined geometry and a romantic silhouette, especially flattering on slender fingers or those seeking a ring that elongates the hand. The semi-set design allows you to select a marquise diamond tailored to your vision and budget.

Resizing is available to ensure a perfect fit, and the low-profile setting makes daily wear effortless, even with gloves or layered bands.
