Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with subtle drama. This three-stone semi-set ring in warm 14K rose gold offers a handcrafted foundation, ready to cradle a 6 x 3.5 mm center stone of your choosing.

Each band is shaped and polished in our Williamsburg studio, the rose gold’s soft blush complementing the marquise’s tapered elegance. The setting’s low profile and secure prongs ensure daily wearability without catching, while the three-stone design balances presence with refined comfort.

Crafted with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness, quietly woven into every facet.

Its slender band and modest height suit hands that appreciate subtle sophistication, and the semi-set style invites personalization—choose your ideal marquise cut to complete the story. The design’s clean lines and gentle curves also make it an excellent candidate for stacking alongside wedding bands or delicate bracelets.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers attentive adjustments with care and precision.
