Sunlight catches the sharp edges of a 6 x 6 mm square diamond, casting a precise, architectural sparkle that anchors this engagement ring’s quiet confidence. Crafted in warm 14K rose gold, the band’s subtle sheen complements the gem’s geometric clarity without distraction.

The low-profile setting secures the stone with delicate accents that enhance brilliance while maintaining a sleek silhouette, ideal for everyday wear. Each ring is meticulously finished by hand in our Williamsburg studio, ensuring a smooth comfort fit that slides easily beneath gloves or alongside stackable bands.

Our commitment to sustainability is reflected in the lab-grown diamond’s exceptional clarity and ethical origin, offering a conscious choice without compromise on beauty or durability.

This design suits those who appreciate modern structure paired with practical elegance—its balanced proportions flattering a range of hand sizes and shapes. The ring’s sturdy yet refined build supports daily life’s rhythms with ease.
