Lab-Grown Diamond Engagement Ring
Sunlight catches the soft, rounded corners of a 12 x 12 mm cushion diamond, its gentle glow framed by a semi-set band awaiting your choice of center stone. Crafted from 18K white gold, this mounting balances modern minimalism with structural clarity, its clean lines and subtle accents offering a quiet confidence.
The band’s smooth finish and low-profile setting ensure comfortable daily wear, while the semi-set design invites customization, letting you select a cushion diamond that reflects your personal story. Each ring is meticulously hand-finished in our Williamsburg studio, where precision meets thoughtful design.
Our commitment to lab-grown diamonds means your ring carries a clarity of purpose—ethical origins paired with sustainable craftsmanship. The 18K white gold band complements a variety of skin tones and fits seamlessly alongside other stackable pieces or a wedding band.
Designed for those who appreciate refined geometry and understated elegance, this mounting suits hands seeking a balance of presence and subtlety. Its comfort fit and moderate width make it glove-friendly and ideal for everyday life.
