I’ve started taking some of the classes here. They are well structured and easy to follow, but not overly simplified. I needed a challenge in my life for the summer and these courses fit right in! I’ve always loved rocks and gems, always wanted to learn and expand my hobby. I honestly doubt I would need to be “certified” but hey, you never know! I find that the knowledge that I obtain is well worth the effort. I really would rather spend tuition money on specimens and instruments at this time. I think the Gold membership is a “BARGAIN” considering the information.
