Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set engagement ring foundation in 10K yellow gold frames a 6 x 3.5 mm marquise center with subtle accent settings designed to enhance clarity and structure without distraction.

Handcrafted in Williamsburg, the band’s smooth finish and modest profile ensure comfort for daily wear, while the secure prong setting balances protection with light exposure for lively brilliance. The warm yellow gold complements the stone’s natural fire, creating a modern-minimalist statement of refined confidence.

Each piece reflects our commitment to sustainability through lab-grown diamonds, offering ethical clarity without compromise. The low-profile design suits those who appreciate clean lines and a ring that layers effortlessly with other bands or stands alone with quiet strength.

Resizing is available to ensure a perfect fit, and the semi-set format invites you to select a marquise diamond that matches your vision. Whether visiting our Williamsburg studio or designing online, this ring foundation offers a thoughtful starting point for a personalized symbol of commitment.
