Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 3.75 mm round diamond, poised to sparkle with quiet brilliance. This semi-set solitaire ring foundation, crafted in warm 14K rose gold, invites your choice of a lab-grown center stone to complete its embrace.

The band’s smooth, low-profile silhouette balances subtle presence with everyday comfort, shaped and polished in our Williamsburg studio to a soft glow that complements the diamond’s classic round cut—known for its lively fire and timeless allure. The setting’s delicate prongs are designed to hold your chosen gem securely while allowing light to dance freely across its facets.

Each piece reflects a commitment to sustainability, featuring a lab-grown diamond option that offers clarity and ethical provenance without compromise.

Ideal for those who appreciate understated elegance, this solitaire mounting pairs effortlessly with stacking bands or stands alone as a statement of refined intention. Its modest scale suits slender fingers and adapts well to glove wear, making it a versatile choice for daily life.
