Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a subtle, tapered sparkle that draws the eye along the finger’s natural line. This semi-set solitaire ring offers a handcrafted 14K yellow gold band, shaped and polished in our Williamsburg studio to a smooth, comfortable fit that wears effortlessly every day.

The slender shank supports a low-profile mounting designed to cradle a 9 x 4.5 mm marquise stone, emphasizing its dramatic pointed ends and graceful curves. Each band is meticulously finished by hand, ensuring a tactile warmth and resilience that complements the diamond’s architectural brilliance.

Crafted with lab-grown clarity, this ring reflects a commitment to sustainable luxury without compromise. The ethical origin of the diamond aligns with a modern approach to fine jewelry, mindful of both beauty and impact.

Ideal for those who appreciate a statement piece that remains understated in daily wear, the slim band pairs well with stacking rings or stands alone with quiet confidence. Its low profile fits comfortably under gloves or sleeves, making it as practical as it is striking.

Resizing is available to ensure a perfect fit, with care instructions provided to maintain the band’s polished finish and the stone’s brilliance over time.
