Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of an 8 x 4 mm marquise diamond, it draws the eye along its tapered points, creating a subtle drama that feels both refined and striking. This solitaire semi-set in 14K white gold offers a low-profile setting designed to sit close to the finger, balancing elegance with everyday practicality.

Crafted in Williamsburg, the band is smoothly finished with a comfort fit that eases wear throughout daily routines. The mounting’s precise prongs cradle the stone securely while maintaining a sleek profile that slips easily under gloves or alongside other stackable bands.

Each lab-grown diamond is selected for clarity and brilliance, reflecting Haejin Jewelry’s commitment to sustainable, ethical sourcing without compromising on visual impact. The semi-set design allows you to choose a center stone that perfectly matches your vision, ensuring a personalized expression of commitment.

Ideal for those who appreciate architectural grace paired with subtlety, this marquise solitaire suits slender to medium finger shapes, elongating the hand with its tapered form. Resizing is straightforward, and the studio offers attentive care guidance to preserve the ring’s refined finish.
