Opal and Tourmaline
Opal, a symbol of hope and purity, with brilliant fire and color is an amazing gem. The play of color in the October opal is actually a result of water within the gem.
Tourmaline birthstones are found in almost any color. The most common colors are green and pink. With a hardness of 7 to 7.5 this October birthstone is used in many jewelry applications.
