Lab-Grown Diamond Engagement Ring

Imagine the quiet thrill of a marquise diamond catching the light as you turn your hand—its elongated, tapered silhouette lending a subtle drama that feels both intimate and bold. This semi-set solitaire invites you to select a center stone that measures 8 by 4 millimeters, a shape known for its graceful elongation and vintage allure.

Crafted in 14K yellow gold, the mounting balances warmth with refined structure, designed with a low-profile setting that nestles close to the finger for everyday ease. The band’s smooth finish and gentle taper ensure comfort, while the prongs are precisely shaped to hold your chosen diamond securely without overpowering its delicate form.

Each piece is meticulously finished in our Williamsburg studio, where expert hands inspect every curve and angle to meet exacting standards. The use of lab-grown diamonds reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

This ring suits those who appreciate a blend of classic romance and modern wearability—its slender silhouette complements slender to medium finger sizes and layers effortlessly with wedding bands or stackable rings. Its low profile also makes it glove-friendly, ideal for daily life in Brooklyn’s changing seasons.

Should you wish to adjust the band size, resizing is straightforward and handled with care to preserve the ring’s integrity. Lead times vary slightly depending on stone selection but we keep you informed throughout the process.
