Research Room

When a conclusion cannot be found for a gem using ordinary grading or identification methods, that gem is put through even more advanced analysis in the research room. These stones are observed using a highly advanced system operated by an expert senior technician using the latest analysis equipment capable of examining complex treated and synthetic gems. This wealth of knowledge and expertise is also needed in the field of research and we are moving forward with our own unique research to search for the color origin of rubies and sapphires and to identify the location of production. The benefits of this research are not only used in the daily identification and grading of stones, but also continually utilized in presentations at academic conferences inside and outside Japan to increase international awareness and build a strong cooperative relationship with major laboratories around the world.
