Lab-Grown Diamond Engagement Ring
Sunlight catches the soft, rounded edges of a 7 x 7 mm cushion diamond, its gentle glow unfolding like a quiet promise. This semi-set engagement ring offers a refined foundation, crafted from warm 18K yellow gold that embraces the stone with subtle strength and modern clarity.
The band’s smooth profile balances comfort with structure, designed to sit close to the finger without overwhelming daily wear. Accents along the shank add a whisper of sparkle, enhancing the cushion’s vintage-inspired softness with a contemporary edge. Each piece is meticulously finished in our Williamsburg studio, where hand polishing and rigorous inspection ensure a flawless surface and enduring shine.
Our commitment to ethical jewelry is reflected in the lab-grown diamond’s exceptional clarity and sustainable origin, offering brilliance without compromise. This ring suits those who appreciate a confident yet understated statement, pairing effortlessly with stackable bands or worn solo for a quiet declaration of intent.
Should you need a custom fit, resizing is handled delicately in-house to maintain the band’s integrity and comfort. Lead times are transparent, with personalized guidance throughout the design process.
