These earrings have been made from vintage components sourced from old warehouse stock. The earring post-back cup was made for Sarah Coventry circa 1970s-80s. Pearl cabochons circa 1960s have been placed into those cups and then finished with lustrous Japanese-made pearl beads from the 1950s.
They measure 3.5 cm from the top of the cup to the base of the drop.
These earrings have been lovingly made with vintage materials which hold some evidence of their former life in a deepened patina and minor wear. I think that is what gives them so much charm.
