Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise diamond, casting a subtle, tapered sparkle that dances with every movement. This 12 x 6 mm center stone is nestled in a platinum setting, its cool sheen framing the gem with quiet strength and refined precision.

Handcrafted in our Williamsburg studio, the ring features delicate accent stones that enhance the marquise’s dramatic silhouette without overpowering its architectural grace. The platinum band is polished to a smooth comfort fit, designed for daily wear with a low-profile setting that slips easily beneath gloves or sleeves.

Each diamond is lab-grown, offering a clarity and brilliance that honors both the environment and your values. The ethical origin of the stone complements the meticulous craftsmanship, creating a piece that feels as conscientious as it does captivating.

Ideal for those who appreciate bold geometry paired with artisan detail, this ring balances statement presence with subtle wearability. Its shape elongates the finger, while the slender band invites stacking or solo elegance.

Should you need a custom size, resizing is available to ensure a perfect fit without compromising the ring’s integrity.
