Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a cushion diamond, its gentle glow unfolding like a quiet promise. This three-stone semi-set engagement ring frames an 11 x 11 mm center stone with two delicate side gems, each carefully positioned to enhance the central brilliance without overpowering it.

Crafted from warm 10K yellow gold, the band is shaped and polished in our Williamsburg studio, where every curve is refined for a comfortable, low-profile fit that sits close to the finger. The artisan finish reveals subtle handwork details—smooth edges and secure prongs—that ensure daily wearability without fuss.

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

This ring suits those who appreciate a balance of presence and subtlety, its three-stone design lending a narrative depth while the cushion cut’s soft geometry complements a variety of hand shapes. Its modest profile makes it ideal for stacking or pairing with a wedding band.

Should you wish to adjust the band size, resizing is available to ensure a perfect fit without disrupting the ring’s integrity.
