Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a delicate arc of light. This three-stone engagement ring in platinum frames a 6 x 3.5 mm marquise center with two gently flanking stones, each set low to rest comfortably against the finger.

Handcrafted in our Williamsburg studio, the ring’s platinum band is polished to a soft sheen, offering durability without weight. The low-profile setting ensures ease of wear beneath gloves or daily tasks, while the three-stone arrangement balances visual drama with subtlety.

Each diamond is lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness. The marquise shape’s distinctive, tapered geometry lends a refined elongation to the hand, ideal for those who appreciate architectural elegance with a whisper of romance.

Designed for everyday grace, this ring suits a wearer who values comfort and understated sophistication, whether worn solo or stacked alongside complementary bands. Resizing is available to ensure a precise fit, crafted with the same care as the original design.
