Lab-Grown Diamond Engagement Ring

Imagine the soft glow of a 9 x 9 mm cushion diamond poised to catch the light with a gentle vintage warmth, its rounded corners offering a subtle contrast to the sharp geometry of traditional cuts. This semi-set solitaire mounting in 18K rose gold provides a warm embrace for your chosen stone, while the white gold accents lend a quiet modern edge.

Crafted with a low-profile setting, the band sits close to the finger, designed for everyday wear without catching or discomfort. The smooth finish and balanced weight ensure a comfort fit that feels natural from morning coffee to evening strolls. Each ring is meticulously inspected in our Williamsburg studio, where precision meets thoughtful design.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and brilliance with a significantly reduced environmental footprint.

This solitaire setting suits those who appreciate refined simplicity and a ring that layers effortlessly with wedding bands or stackable styles. Its modest height makes it glove-friendly and ideal for active lifestyles.

Should you need resizing, our Brooklyn studio offers expert adjustments to ensure your ring fits perfectly over time.
