Solitaire Diamond Institute and Gem Testing Lab

Diana deepthi did a great job facilitating the gold appraisal course.Her enthusiasm and knowledge kept the team engaged throughout the session. To make future sessions even more impactful, I would suggest DGI institute. Overall, it was a very valuable experience, and the core objectives were definitely met."

Excellent Gold Appraisal class! The training was clear, practical, and easy to understand. I gained valuable knowledge and feel much more confident in assessing gold. Highly recommended for anyone interested in jewellery appraisal.

I learned new things about gold and its purity, and I enjoyed using the touchstone to check its purity. Diana, ma'am, was so good; she was very friendly to everyone in the class.

"The training was very good and helpful. I learned many new things and gained better understanding about the work process. The trainer explained everything clearly and in a simple way. This training will help me in my job. Thank you."
