Sunlight catches the softly rounded corners of a 10 x 10 mm cushion-cut diamond, its gentle glow unfolding like a quiet promise. This engagement ring, set in cool 14K white gold, balances presence with subtlety through a low-profile mounting designed for everyday grace.
Each accent stone is meticulously placed to enhance the cushion’s vintage-inspired shimmer without adding bulk, while the polished band offers a smooth comfort fit that slides easily beneath gloves or alongside other rings. The setting’s precision ensures the diamond sits secure yet accessible to light, maximizing brilliance without compromising wearability.
Crafted in our Williamsburg studio, this ring features a lab-grown diamond—an ethical choice reflecting a commitment to sustainability and clarity. The stone’s soft square shape lends an architectural elegance that complements a range of hand sizes and styles.
Ideal for those seeking a refined, stackable piece that endures daily life, this ring’s design respects both form and function. Resizing is available to ensure a perfect fit, with care instructions tailored to preserve the diamond’s radiance over time.
