Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of an 8 x 4 mm marquise diamond poised to elongate the finger with its tapered silhouette—an emblem of refined confidence. This semi-set engagement ring foundation in 18K white gold offers a sleek, modern-minimal frame, designed to highlight your chosen center stone with delicate accent details that catch light without overwhelming.

Crafted in Williamsburg, Brooklyn, the band’s polished finish and precise low-profile setting ensure comfortable daily wear, while the clean lines maintain a contemporary clarity. The mounting’s structure balances strength and elegance, allowing your marquise diamond to shine with architectural grace.

Each piece reflects our commitment to ethical jewelry through lab-grown diamonds, reducing environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate minimalist design with a confident edge, this setting pairs beautifully with slender bands for stacking or stands alone as a statement of subtle sophistication. Its low profile fits easily under gloves and complements a variety of hand shapes.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly into your life.
