Sunlight catches the softly rounded corners of a 9 x 9 mm cushion-cut diamond, its gentle glow unfolding like a quiet Brooklyn afternoon. This engagement ring, set in warm 14K yellow gold, balances modern minimalism with structural clarity, where each accent stone frames the center with subtle precision.
Crafted in Williamsburg, the band’s smooth finish and low-profile setting ensure a comfortable fit for daily wear, while the secure prongs cradle the diamond without excess metal. The ring’s refined geometry allows light to dance through the facets, revealing the cushion’s signature soft vintage glow with a contemporary edge.
Ethically sourced, the lab-grown diamond offers a sustainable alternative, reflecting Haejin Jewelry’s commitment to responsible craftsmanship without compromise.
Designed for those who appreciate confident understatement, this ring pairs effortlessly with stackable bands or stands alone as a statement of enduring elegance. Its balanced proportions suit a variety of hand shapes, while the comfort fit invites everyday wear without distraction.
Should you need resizing, our Brooklyn studio offers expert adjustments to ensure a perfect fit, with care instructions provided to maintain brilliance over time.
