The charming mineral tree—was a gift from Dr. Alfred Whittaker and his wife Jane when visiting me in 2000. The base of the tree is rose quartz. The leaves are sodalite, a mineral discovered by Karl Ludwig Giesecke between 1806 and 1808 during his long sojourn in Greenland when he was exploring the mineral reources and, incidently, flora on the west coast of that island.
