This is an anklet but can be worn as a bracelet if you want to. This is either sterling or gold and the gems are all real.
You would wear this and it would work to heal you all over and to make sure all hormones are working correctly.
I think this is sterling with gold over it. All the gemstones that are on the bracelet/anklet are there for a reason and all work together.
You can use this whenever you want but you should always cleanse the crystals or gems before using it again.
