TUESDAY, APRIL 21, 7:00 P.M.
As the birthstone of April, the diamond is arguably the most popular and sought after gemstone for the past several hundred years, owning its reputation from its rarity, durability and cultural status. However, there is a notable scientific value behind the glamour. Diamond’s simple chemistry of pure crystalline carbon has made it a valuable tool for industry and cutting-edge science experiments. This presentation will be in the spirit of the late Dr. George Rossman, where grad student and PLS member Paolo Sanchez will discuss the geology, chemistry, synthesis and applications of diamonds beyond simply its status as a gemstone.
This program meeting takes place on Tuesday, April 21, 2026 at 7:00 p.m. in the Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007.
