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-inspired shimmer. This semi-set engagement ring foundation in 18K yellow gold offers a warm, tactile presence, designed to cradle your chosen center stone securely while maintaining a low profile for everyday grace.
Crafted in Williamsburg, the band’s subtle accents enhance the cushion’s rounded corners without overwhelming its soft geometry. The smooth finish and comfort fit ensure the ring feels as natural on the hand as it looks, slipping easily beneath gloves or alongside stackable bands.
Each piece reflects our commitment to ethical jewelry: the setting awaits your lab-grown diamond, a choice that honors sustainability without compromise. The semi-set style invites personal expression, allowing you to select a cushion cut that matches your vision and lifestyle.
Resizing is straightforward, handled with care in-studio to preserve the band’s integrity and finish. Whether you visit us in Brooklyn or design remotely, this ring foundation is a thoughtful start to a custom engagement ring made for daily life.
