Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of a marquise diamond, casting a slender, dramatic silhouette that seems to stretch beyond the finger. This 9 x 4.5 mm marquise center stone is cradled within a delicate halo of micro-pavé diamonds, amplifying its fiery sparkle while maintaining an elegant profile.

Crafted from warm 14K rose gold, the band is hand-finished in our Williamsburg studio, its smooth comfort fit designed for everyday wear. The low-profile halo setting balances brilliance with practicality, ensuring the ring slips easily beneath gloves or sleeves without catching.

Each diamond is lab-grown, offering a clarity and fire comparable to mined stones but with a lighter environmental footprint. This ethical choice reflects a commitment to sustainability without compromising on radiance.

Ideal for those drawn to vintage-inspired shapes with a modern twist, the marquise’s tapered points elongate the finger, while the halo adds a whisper of ornate detail that complements stacking or solo wear. The ring’s balanced scale suits a variety of hand sizes, making it a versatile expression of personal style.

Should you need resizing, our in-house artisans ensure a precise, seamless adjustment that preserves the ring’s integrity and comfort.
