This gem, of extremely fine quality, can be dated to within a very short time span. The style of Nero's coiffure as seen on the gem was introduced in coinage in A.D. 64. This confirms the identification of his companion as his wife Poppaea, whom he married in A.D. 62., rather than his mother Agrippina, whom he appears with on coins only early in his reign. Poppaea died in A.D. 65, and the gem is not likely to have been engraved much after her death, thus the likely date of the gem is circa A.D. 64-65.
