The goal of the Jewelry Glossary Project is to create shared definitions of key terms within the jewelry industry for use by the trade and the public. The project was launched to increase transparency throughout the supply chain, by building consensus on definitions for key terms and creating accountability for their usage. 

A working group comprising jewelry designers, gemstone wholesalers, goldsmiths, educators, and sustainability experts defined the terms below. These definitions were written for use within the specific context of jewelry, so please approach them through that lens.
