    Hi,
    Regarding the recent lesson on gemstones, I wanted to express my concerns. First, I expected a high level of audio and video quality, which was not met. Additionally, the lecturer struggled to present the material clearly and professionally, resulting in a low level of instruction. I also noticed that the lecturer frequently paused to drink water, which raises questions about her ability to maintain focus. It's important to understand that expertise in a field doesn't always translate to effective teaching. I would appreciate it if you could address these issues and consider ways to improve the instruction.
    Thank you,

    Interesting subject. Too bad Dr. Magana's broadcast didn't have much bandwidth. It was a struggle to listen.

    Is it from a scientific point of view possible that colored diamonds can change or fade in decades/ centuries of time? Because there are some stories from fancy colored experts that pink diamonds can go deeper in color over time? Like the moussaieff red diamond. It was a straight RED and became after new grading from gia a Purplish RED

    So I'm not sure what to do about getting a rough diamond authenticated or anything in the united states' I know it's extremely rare to find any but I did from all the test I learned to do online at home and purchasing a diamond tester everything says I'm on point the gravity test says density is 3.5 and I'm a poor man who doesn't have industry backing how can I get my stones checked out

    Thank you! Fantastic information. Just a question.
    Is it possible to change the word "defect" (negative connotation) to "characteristic" a more neutral word?
    Imagine selling a diamond and explain to the client that the reason for the magnificent color of the diamond is defects in their structure.
    Best regards.
