Huge lemon crystal genuine garnet gold tone pendant white opalescent chain

This is an absolutely gorgeous vintage lemon lime crystal with genuine garnet gold tone pendant and white opalescent bead chain. The stone is huge and measures 42 millimeters long and 20 millimeters wide. I’m not sure if the stone is made of lime quartz or crystal glass. There are 3 natural garnet stones on the corner top of the pendant. The chain is made of gold tone metal and opalescent beads and measures 24 inches long. There is a tiny bit of metal tarnish on the frame of the pendant that comes with its age, otherwise in great vintage condition.
