Turn memory into something meaningful — a diamond designed to last.
Our Personal Carbon Diamond service creates a beautiful lab-grown diamond using a meaningful carbon source, such as pet fur or ceremonial ash connected to someone special. Each diamond is grown in a controlled laboratory environment and crafted into fine jewelry designed for long-term wear and remembrance.
Diamonds are available in a wide selection of shapes, sizes, and colors. From soft pink heart shapes to radiant yellow princess cuts, every stone is individually created and set into handcrafted jewelry.
All diamonds are produced using advanced laboratory growth technology and meet quality standards for fine jewelry. Each finished piece includes a Brand Authenticity Certificate, and customers are guided through the full process — from secure sample submission to final delivery.
