Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of a heart-shaped diamond, it reveals a quiet promise—intimate and unmistakable. This semi-set solitaire ring invites you to choose a 7 x 7 mm heart-cut center stone, its soft silhouette poised to capture both brilliance and sentiment.

Crafted in 18K white gold, the mounting is designed with a low-profile setting that hugs the finger comfortably, making it ideal for everyday wear. The band’s smooth finish and subtle taper ensure it sits securely without excess bulk, while the prongs cradle the stone with precision, balancing protection and light exposure.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and sparkle with a smaller environmental footprint. This choice aligns with a modern approach to sustainability without compromising on elegance.

Its streamlined shape suits hands that appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable accents. The heart shape’s romantic form adds a personal touch, especially for those drawn to symbolic design.
