I've got some gorgeous, brand new amethyst jewelry in my store!
Amethyst is the royal purple version of quartz. There is also a stone called prasiolite that is also known as green amethyst - both are the birthstone for February. It was used in ancient Roman times as an amulet to ward of drunkeness (I wouldn't recommend that :P)
Treat yourself to a beautiful purple bauble from my line of amethyst jewelry, or guys - come on, you know she wants a fabulous necklace for her birthday.
A fine selection of purple amethyst set in rings and necklaces.
A lovely green amethyst ring, size 9.
