Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise, casting a slender beam that seems to stretch beyond the hand. This semi-set engagement ring foundation in 14K yellow gold offers a sleek, modern-minimal frame designed to highlight an 8 x 4 mm marquise center stone of your choosing.

Crafted with precision in Williamsburg, Brooklyn, the band’s smooth finish and subtle taper ensure a comfortable fit that sits low against the finger, ideal for daily wear. The mounting’s clean lines and secure prong setting promise both clarity and structure, allowing light to dance freely through the stone’s pointed ends.

Each piece reflects a commitment to ethical jewelry, featuring lab-grown diamonds that combine brilliance with sustainability. The warm yellow gold complements the marquise’s dramatic shape, enhancing its confident geometry without distraction.

Designed for those who appreciate refined simplicity, this mounting pairs effortlessly with stacking bands or stands elegantly alone. Its low-profile setting is glove-friendly and balances well on slender or average finger sizes.
