Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise center, casting a slender, dramatic silhouette that stretches gracefully across the finger. This three-stone engagement ring balances architectural presence with subtlety, its 10 x 5 mm marquise lab-grown diamond securely nestled in a low-profile platinum setting.

Crafted in Williamsburg, the ring’s platinum band is polished to a satin finish that resists daily wear while maintaining a refined glow. The three-stone design offers both visual depth and a comfortable fit, with a smooth interior contour that slides easily beneath gloves or alongside stackable bands.

Each diamond is ethically sourced from the lab, ensuring clarity and brilliance without the environmental cost of traditional mining. This ring’s streamlined profile suits those who favor understated elegance paired with durable craftsmanship.

Ideal for hands that appreciate a slender, elongated shape, the marquise center enhances finger length and pairs well with both minimalist and vintage-inspired styles. Resizing is available to ensure a precise fit, with care instructions provided to maintain the platinum’s subtle sheen.
