Holy Lance
A Holy Lance is conserved in Vagharshapat (previously known as Echmiadzin), the religious capital of Armenia. It was previously held in the monastery of Geghard. The first source that mentions it is a text "Holy Relics of Our Lord Jesus Christ", in a thirteenth-century Armenian manuscript. According to this text, the spear which pierced Jesus was to have been brought to Armenia by the Apostle Thaddeus. The manuscript does not specify precisely where it was kept, but the Holy Lance gives a description that exactly matches the lance, the monastery gate, since the thirteenth century precisely, the name of Geghardavank (Monastery of the Holy Lance).
Seamless robe of Jesus
According to the Gospel of John, the soldiers who crucified Jesus did not divide his tunic after crucifying him, but cast lots to determine who would keep it because it was woven in one piece, without seam. A distinction is made in the New Testament Greek between the 
"himatia" (literally “over-garments”) and the seamless robe, which is "chiton", (literally "tunic" or "coat").
