Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances with every movement. This three-stone semi-set engagement ring in warm 10K yellow gold frames a 10 x 5 mm marquise center, its tapered points drawing the eye along the finger’s natural line.

Each element is crafted with care in our Williamsburg studio: the low-profile setting balances presence with everyday wearability, while the smooth band offers a comfort fit that feels as natural as a second skin. The side stones echo the center’s graceful shape, enhancing its subtle drama without overwhelming.

Our diamonds are lab-grown, chosen for their clarity and brilliance with a mindful approach to sustainability and ethical sourcing.

This ring suits those who appreciate refined elegance with a whisper of vintage romance—its slender profile slips easily beneath gloves and stacks beautifully with complementary bands. The semi-set design invites you to select a center stone that reflects your personal story.

Resizing is available to ensure a perfect fit, and each piece undergoes meticulous inspection before it leaves our Brooklyn studio.
