Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of a 12 by 10 mm emerald cut diamond, its glassy planes reflecting a quiet architectural elegance. This semi-set halo engagement ring offers a refined foundation in 18K white gold, meticulously crafted in our Williamsburg studio to cradle your chosen center stone with precision and care.

The band’s low-profile setting balances presence with everyday wearability, its smooth finish ensuring comfort against the skin. Each prong is hand-formed and inspected to secure the stone while allowing light to dance freely across the emerald’s signature step cuts. The halo setting adds a subtle frame, enhancing brilliance without overwhelming the ring’s clean lines.

Crafted from ethically sourced lab-grown diamonds, this piece embodies a commitment to sustainability and clarity, reflecting a modern approach to fine jewelry. The cool white gold complements the emerald’s elongated shape, ideal for those who appreciate architectural geometry and a statement that feels both bold and wearable.

Designed for hands that value understated sophistication, this ring pairs effortlessly with stackable bands or stands alone as a singular expression of intention. Its comfort fit and modest profile make it glove-friendly and suited for daily life.
