This is reduced due to significant dicolouration of the chain and the links.
A bracelet that doubles up as a pendulum, the catch to do up the bracelet can be used to clip the pendulum weight off or on.
The beads are made up of quartz, amethyst, sodalite, green quartz, citrine, carnelian and haematite with a quartz pendulum weight.
The whole length including the pendulum weight is about 28cm long.
The quartz weight alone measures about 3cm long.
NB If you have a silver cloth and some time you can probably clear a lot of the discolouration off.
Yours will be one of the ones from the photos.
