gemmed

   “After dark it was a beautiful sight to look down on our rudders, from which rushed eddying streams of phosphoric light gemmed with whirling sparks of fire. It resembled (more nearly than anything else to which I can compare it) one of the large irregular nebulous star-clusters seen through a good telescope, with the additional attraction of ever-changing form and dancing motion.”

   “The linkage of northern and southern Christian concerns is evident in the oldest surviving great golden and gemmed altar frontal with historiated narratives in Sant'Ambrogio in Milan, commissioned between 824 and 859 in an area fairly recently absorbed into Carolingian control”
