Up for sale is an authentic mid-century souvenir export necklace purchased directly in Hong Kong during the 1960s. This continuous 29-inch opera-length chain features genuine natural jadeite tube beads that are beautifully translucent when backlit, revealing a light green color matrix with organic dark green "moss-on-snow" veining. The untreated gemstones alternate with detailed geometric Greek Key openwork filigree stations crafted from a highly durable, strong base metal with heavy gold electroplating that remains bright and tarnish-free. This seamless, endless loop slip-on design has no clasp and is in excellent vintage condition with completely intact stones and secure links.
