January 11, 2018: Thursday. 7:30 PM Speaker Gloria Staebler on “Beyond the Four Cs, A Diamond Alphabet.”

Everyone is familiar with the 4Cs of faceted diamonds – color, cut, clarity, and carat – established by the jewelry industry in the 1940s. But for collectors diamonds hold a whole alphabet of characteristics. From Arkansas to Zimbabwe, diamonds are embedded not just in our cratons but in our cultures. Diamonds are scientific and archeological breadcrumbs that have shaped what we know of our planet and our past in ways you may have never imagined, and with diamond technologies coming to the fore, they may likewise shape our future. This talk with touch on the tantalizing tentacles of diamond.
