What is jujube wood? In Christian tradition, the jujube tree was identified as the thorn bush used to weave Christ's crown of thorns. Based on this tradition, Christian pilgrims to the holy land would take branches of this tree home as symbols of Christ's sacrifice. The wood is heavy and durable and serves for artistic woodwork.
