@elliottbnewcombjr Do you believe your eyes? Compare the pictures. As I said, the diamond is full of contamination, one edge is obviously pitted. The contact patches are well cut and polished and the stylus is perfectly oriented. But a diamond that contaminated is obviously going to be softer. Just looking at the Soundsmith stylus, another microridge, which do you think is going to last longer? However, the Jico is a $285 item VS all those others that are in $10K plus cartridges. You get what you pay for and in this case it is a very serviceable stylus, it just won't last as long. I'll buy another to hold is reserve. what is really going to be fun is comparing the V15 to my other cartridges when my moving coil phono stage returns. It has a little gremlin the factory took care of.
Trying to predict a styluses life span is a fool's errand. There are way to many variables involved to be able to predict this, VTF, AS, Cleanliness, diamond purity, polish, contact patch area plus whatever I am missing. There are things you can say about it like, lower VTFs will prolong life, clean records will prolong life and so forth.
