Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, luminous silhouette across your hand. This 9 x 4.5 mm marquise center stone is set low in a 14K yellow gold band designed for everyday grace and ease.

Crafted with precision, the setting secures the diamond with delicate accents that enhance its tapered drama without adding bulk. The band’s smooth finish and modest profile ensure comfort beneath gloves or alongside stackable rings, making it a seamless companion for daily wear.

Each lab-grown diamond is chosen for clarity and brilliance, reflecting a commitment to sustainable, ethical jewelry without compromise. The warm glow of yellow gold complements the stone’s fiery facets, creating a harmonious balance between classic warmth and modern design.

This ring suits those who appreciate refined geometry and subtle sophistication, especially hands that favor elongated shapes or a slender silhouette. Its low-profile setting minimizes snagging, while the comfort fit invites continuous wear.

Should you need resizing, our Brooklyn studio handles adjustments with care to maintain the ring’s integrity and finish.
