email sent by Mr. John Koivula to Dr. A. Peretti commenting on “Contributions to Gemology”: Dear Dr. Peretti, In Tucson this year Mark Smith delivered both volumes of your excellent “Contributions to Gemology” including the very informative and computer-useful VCD. Thank you for sending these! I would have responded sooner, but I wanted to be able to read No. 2 first, and have now had the chance to do so. These are both very useful publications of the highest quality that all serious gem(m)ologists should have in their libraries. On a personal note I particularly enjoyed the study on Painite in issue 2. I am sure you are already hard at work on the next issue (3) and I for one am looking forward to it. You are doing excellent work that helps us all. Sincerely, John Koivula
