Lab-Grown Diamond Engagement Ring

Imagine the quiet confidence of a 12 x 12 mm cushion-cut diamond poised to catch the light with its soft, vintage-inspired glow. This semi-set solitaire mounting in 18K white gold offers a refined low-profile silhouette, designed to sit close to the finger for everyday ease and subtle elegance.

Crafted in Williamsburg, the band is meticulously shaped for comfort fit, its smooth finish ensuring it slips on effortlessly and wears well beneath gloves or stacked with other bands. The prong setting balances security with minimal metal presence, allowing the chosen cushion stone to become the unmistakable focal point.

Each piece reflects Haejin Jewelry’s commitment to ethical sourcing, featuring lab-grown diamonds that combine clarity and sustainability without compromise. The cool sheen of 18K white gold complements the cushion’s gentle facets, creating a harmonious interplay of light and metal.

Ideal for those seeking a solitaire that merges classic form with modern practicality, this mounting suits a range of hand sizes and shapes, especially those who value a ring that integrates seamlessly into daily life.
