Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise center stone stretches gracefully across the finger, its pointed ends drawing the eye with subtle drama. This semi-set halo ring in 10K white gold frames a 12 x 6 mm marquise diamond, designed to amplify brilliance while maintaining a low profile for everyday comfort.

Crafted with precision, the halo setting surrounds the center stone with a delicate circle of pavé diamonds, enhancing light reflection without adding bulk. The band’s smooth finish and modest width ensure a secure, comfortable fit that slips easily beneath gloves or alongside other stackable rings.

Each piece is hand-finished in our Williamsburg studio, where expert jewelers inspect every facet and setting to meet exacting standards. The choice of 10K white gold balances durability with a refined sheen that complements the diamond’s icy clarity.

Ethically sourced, the lab-grown diamond offers a sustainable alternative with the same optical properties as mined stones, reflecting a commitment to responsible luxury.

This design suits those seeking a statement ring that remains practical for daily wear, especially flattering on slender fingers or anyone who prefers a ring that feels light and unobtrusive.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly.
