Lab-Grown Diamond Engagement Ring

Imagine the quiet geometry of an Asscher cut diamond, its step facets catching light like a secret held close. This semi-set halo mounting in 18K white gold frames a 5x5 mm center stone with precision, designed to showcase the diamond’s architectural clarity while maintaining a low profile for everyday grace.

Crafted in Williamsburg, the band’s smooth finish and secure halo setting balance durability with refined detail, ensuring comfort beneath gloves or alongside stackable bands. The setting’s subtle elevation protects the stone without sacrificing wearability, making it a practical choice for daily life.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and brilliance with a smaller environmental footprint. The cool white gold complements the Asscher’s glassy, elongated facets, enhancing its vintage-modern appeal.

Ideal for those who appreciate clean lines and understated strength, this ring suits hands that favor architectural shapes and a confident, modern silhouette. Resizing is available to ensure a perfect fit, crafted with care in our Brooklyn studio.
