Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that seems to stretch beyond the finger. This 12 x 6 mm marquise center stone is embraced by a delicate halo of pavé-set lab-grown diamonds, each meticulously placed to amplify the ring’s luminous architecture.

Crafted in warm 14K yellow gold, the band is shaped for comfort with a subtle taper that balances the stone’s bold profile. The halo setting sits low enough to slip easily beneath gloves or stack alongside other bands without catching, while the artisan finish reveals hand-polished facets and precise prong work from our Williamsburg studio.

Each diamond is lab-grown, offering clarity and brilliance with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise on sparkle.

This ring suits those drawn to refined drama—elongating the finger with its tapered shape and halo glow, ideal for everyday wear or layering with complementary bands. The comfort fit ensures it remains a daily companion, not just a statement.

Should you need resizing, our in-house jewelers provide careful adjustments to maintain the ring’s integrity and balance.
