Livestream Lecture: Nature's Art in Stone

This is the second program in the Natural Beauties lecture series.

Faceted gems are prized for their obvious sparkle and brilliance, but it is in the dramatic colors, intricate patterns and sublime textures of the lapidary stones such as malachite, lapis lazuli, jade, jasper, and agate that the wonder of nature’s artistry is fully revealed.

The stone medium permanently records these masterpieces that inspire craftsman and artists to create spectacular ornaments and objets d’art.  This illustrated talk will explore the stories behind the many beautiful precious stones represented in Natural Beauties.


This virtual lecture is presented live via Zoom. The online "waiting room" opens at 6 p.m., and the lecture will begin at 6:30  p.m. Participants can submit questions via the chat feature.
