Research and development of hardware system for gemstone color identification device

Abstract

Color is a crucial factor in determining the value of a gemstone. However, establishing a standardized color system for different types of gemstones remains a significant challenge in the jewelry industry. Currently, color identification methods rely heavily on subjective color grading scales and manual assessment by experts. To address this issue, a new device called the GCIM (Gemstone color identification machine) has been developed. Its purpose is to digitize color measurements of gemstones and replace manual assessment, thereby promoting the advancement of the jewelry industry and improving efficiency and accuracy in gemstone appraisal processes. This study presents a new proposal for gemstone color classification and integrates hardware to enable gemstone color assessment based on this new system. This allows for a quantified measurement of gemstone color, providing a visual description. The GCIM device is currently undergoing the patent application process.
