Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, luminous shadow that dances with every movement. This three-stone engagement ring in platinum frames a 10 x 5 mm marquise center with two delicate side stones, emphasizing architectural clarity and modern balance.

Handcrafted in our Williamsburg studio, the ring features a low-profile setting that sits close to the finger, offering both comfort and durability for daily wear. The polished platinum band is meticulously finished to a smooth comfort fit, its subtle weight grounding the sculptural elegance of the stones.

Each diamond is lab-grown, chosen for its exceptional clarity and ethical origin, reflecting a commitment to sustainability without compromise. The marquise shape’s tapered points elongate the hand, while the three-stone arrangement adds depth and narrative, ideal for those who appreciate refined geometry with a personal story.

Designed for those who favor minimalist sophistication, this ring pairs effortlessly with stacking bands or stands strikingly alone. Its low profile makes it glove-friendly and unobtrusive, perfect for an active lifestyle.

Resizing is available to ensure a precise fit, crafted carefully in-house to maintain the ring’s structural integrity. Typical lead times reflect our bespoke approach, allowing for thoughtful customization.
