Lab-Grown Diamond Engagement Ring

Imagine the quiet thrill of a heart-shaped diamond poised to catch the light, its soft curves echoing a personal promise. This semi-set engagement ring offers a handcrafted 18K yellow gold band, gently rounded for comfort and polished to a satin sheen that complements the stone’s delicate silhouette.

Each band is shaped and finished in our Williamsburg studio, where artisans refine every contour to sit low on the finger, ensuring a subtle profile that slips easily beneath gloves or alongside other rings. The solitaire setting awaits your choice of a 5 x 5 mm heart-shaped diamond, known for its romantic form and luminous sparkle.

Crafted with lab-grown clarity, this ring reflects a commitment to sustainable luxury without compromise. Its warm gold tone suits those who favor a classic yet intimate expression, especially flattering on slender hands or as a centerpiece in a curated stack.

Should you need adjustments, resizing is handled delicately in-house to preserve the band’s smooth finish. Typical design lead times allow for thoughtful customization, ensuring your ring is as unique as your story.

We invite you to explore this design in person at our Williamsburg studio or begin your custom journey online, where expert guidance meets personal vision.
