Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone semi-set engagement ring in 14K yellow gold frames a 9 x 4.5 mm marquise center with two gently tapered side stones, creating a balanced, architectural presence without excess height.

Crafted for everyday wear, the low-profile setting keeps the stones secure close to the finger, while the smooth band offers a comfort fit that slides easily beneath gloves or alongside stackable rings. Each piece is meticulously finished in our Williamsburg studio, where precision meets subtlety in every curve and prong.

Choosing a lab-grown diamond means embracing clarity and brilliance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

The elongated marquise shape visually lengthens the finger, ideal for those who appreciate a refined yet distinctive statement. Its three-stone layout adds dimension without bulk, making it a versatile choice for daily life and special moments alike.

Should you need a custom size, resizing is straightforward and handled with care to maintain the ring’s integrity.
