I found this information on what a cabochon is amazingly satisfying. I have been trying to get more thorough info ever since I began collecting Tiffany style lamps. When friends or relatives would ask me what cabochons were I said I thought they were a kind of quartz. Now I understand better than ever and am so appreciative for the explanations.
I am most grateful. Thank you to any and all who offered up such interesting info. I will sleep well tonight. JN.
