Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of your finger framed by an 8 x 4 mm marquise diamond, its tapered points catching light with a quiet, refined drama. This solitaire semi-set ring offers a sleek foundation in 18K white gold, engineered for a low-profile silhouette that slips comfortably beneath daily gloves and sleeves.

Crafted in Williamsburg, Brooklyn, the mounting features precise prongs that cradle the stone securely while maintaining a streamlined profile. The band’s gentle curve and polished finish ensure a balanced feel, designed to wear seamlessly alongside other stackable pieces or alone as a statement of modern elegance.

Each lab-grown diamond is selected for clarity and brilliance, reflecting Haejin Jewelry’s commitment to ethical sourcing and sustainability without compromise. The semi-set design invites you to choose a center stone that resonates personally, allowing for a tailored expression of your engagement story.

Ideal for those who appreciate architectural grace with everyday practicality, this setting suits slender to medium finger shapes, emphasizing length and light. Its low profile reduces snagging, making it a thoughtful choice for active lifestyles.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers attentive adjustments with care and precision, ensuring your ring fits as naturally as it shines.
