Lab-Grown Diamond Engagement Ring
Imagine the quiet confidence of a 6 x 6 mm cushion-cut diamond poised to catch the light with its soft, vintage glow—ready to become the heart of your custom engagement ring. This semi-set foundation in cool, enduring platinum offers a low-profile silhouette designed for everyday grace and resilience.
Expertly crafted in our Williamsburg studio, the mounting features delicate accent settings that enhance sparkle without adding bulk, ensuring a comfortable fit that slides easily beneath gloves or rings stacked alongside. The platinum band is polished to a satin finish, balancing subtle sheen with scratch resistance for lasting wear.
Each piece is designed around a lab-grown diamond, reflecting a commitment to ethical sourcing and environmental mindfulness without compromise on brilliance or clarity.
Ideal for those who appreciate refined craftsmanship and a ring that integrates seamlessly with an active lifestyle, this semi-set allows you to select a cushion diamond that matches your vision and hand shape perfectly.
Should you need adjustments, resizing is handled with care to maintain the integrity of the setting and metalwork. Typical lead times for completion are shared transparently during your consultation.
