Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that dances across the skin. This three-stone semi-set engagement ring in 18K rose gold frames a 9 x 4.5 mm marquise center with two delicate side stones, each facet sculpted to catch light with quiet brilliance.

Handcrafted in Williamsburg, the band’s gentle curve and polished finish offer a comfortable fit that sits low against the finger, ideal for everyday wear. The rose gold’s warm blush complements the diamond’s fiery sparkle, while the three-stone setting balances romantic symbolism with modern refinement.

Each lab-grown diamond is selected for clarity and cut, reflecting a commitment to sustainable, ethical jewelry without compromise. The semi-set design invites you to choose a center stone that resonates personally, making this ring uniquely yours.

Its slender profile suits hands that appreciate subtle elegance and works beautifully alongside stacking bands or a wedding ring. The low-profile setting ensures it slips easily under gloves or sleeves, marrying practicality with poetic form.
