X1-X5 are bone rings found on the left hand of juvenile skeleton
2119, burial 200...in the east-central platform of Building 1.
All five rings had been cut from a single bone and evidence of wear supported the excavator's belief that in two instances there were two on one finger.
Although they appear quite large, the hole is small, suitable only for a fairly small hand, and there is little doubt from the wear evidence that they were worn in life by juvenile 2119, who was buried with everyday rings on the left hand.
