Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set solitaire invites you to choose a 10 x 5 mm marquise stone, its tapered points lending a quiet drama and graceful elongation to the finger.

Crafted in warm 10K yellow gold, the mounting balances delicate strength with everyday wearability. The low-profile setting keeps the diamond close to the skin, while the smooth band offers a comfort fit that feels natural from morning coffee to evening strolls through Williamsburg.

Each lab-grown diamond reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity. This piece is designed for those who appreciate subtle romance and modern craftsmanship in equal measure.

The slender shape suits longer fingers or anyone seeking a ring that complements stacking without overwhelming. Its solitaire simplicity allows the stone’s unique geometry to take center stage, while the yellow gold adds a soft glow that warms the hand.

Resizing is straightforward in our Brooklyn studio, ensuring a precise fit tailored to your lifestyle. Lead times vary slightly depending on stone selection, but every ring is finished and inspected with care before it leaves the bench.
