At Carat & Co we specialize in the wholesale trade of high-quality diamonds, offering both industrial-grade and jewelry-grade diamonds. With decades of experience and an extensive global network, we are proud to provide our clients with unique, exceptionally large diamonds in both rough and semi-finished forms. While we primarily focus on lab-grown diamonds, we also offer natural mined diamonds to meet diverse needs.
Lab-grown diamonds are the perfect choice for industrial applications due to their consistent quality and versatility. We offer a wide range of diamond types suited for different uses, including:
As the global diamond-growing industry continues to expand, we support laboratories and companies with an extensive selection of diamond seeds (up to 30x30 mm) for growing high-quality diamonds. These seeds serve as the foundation for producing diamonds through various growth methods, ensuring top-tier results for all applications.
Our diamonds, available in remarkable sizes, are perfect for a new generation of luxury jewelry. The exceptional dimensions of our lab-grown diamonds allow for unique creations, including diamond-encrusted rings and even complete watch cases made entirely of diamond. Our exclusive brand, PietrAverde, showcases some of these exceptional pieces. We offer colorless diamonds, as well as a range of pastel hues, to suit every design. Additionally, we carry a broad assortment of cut diamonds in popular shapes like brilliant, emerald, princess, pear, and more.
