In the fall of 2025, Chatham released The Ultimate Lab-Grown Catalog. As the leading lab-grown brand, we’ve created an essential reference guide for full-service jewelers. Catalog highlights include extensive stock listings, clear policies and procedures, gemstone education and color lore, understanding growth methods, partnership programs, and more.

Explore the definitive lab-grown catalog—designed to support informed buying, merchandising, and client education.
