The Cross and Crown seal is an internationally registered trademark owned by the Christian Science Board of Directors of The First Church of Christ, Scientist. This jewelry depicting the trademark is being manufactured under license.

Mary Baker Eddy first used the Cross and Crown seal on the cover of the third edition of the Christian Science textbook, Science and Health, issued in 1881. Her Church continues to use it today to mark her writings and the publications she established. Christian Scientists particularly cherish Christ Jesus’ words surrounding the cross and crown, "Heal the sick, raise the dead, cleanse the lepers, cast out demons."
(Matthew 10:8, Revised Version of the Bible)
