Lab-Grown Diamond Engagement Ring
Sunlight catches the soft, rounded corners of a 9 x 9 mm cushion diamond, its gentle glow unfolding like a quiet promise. This semi-set solitaire ring features a 14K yellow gold band, crafted with a low-profile setting that nestles close to the finger for everyday ease.
The band’s smooth finish and subtle taper ensure a comfort fit that resists catching, making it an ideal choice for those who value understated elegance alongside durability. Each piece is meticulously hand-finished in our Williamsburg studio, where precision meets thoughtful design to balance sparkle with wearability.
Our diamonds are lab-grown, offering clarity and brilliance with a smaller environmental footprint, reflecting a commitment to ethical jewelry without compromise. The cushion shape’s soft edges and vintage-inspired silhouette flatter a variety of hand shapes, while the solitaire style allows the diamond’s natural fire to take center stage.
Designed to pair effortlessly with other bands or worn solo, this ring suits those who appreciate refined craftsmanship and a subtle statement. Resizing is available to ensure a perfect fit, with care instructions provided to maintain the ring’s polished surface over time.
