Anyways amethyst is a good substitute for 
blue sapphire, and it's easy to find uncracked amethyst gemstones. 

 If a fresh tumor is swelling on one’s body, he should dampen the amethyst with his saliva and touch the tumor all over with it. The tumor will grow smaller and disappear. Pass that stone over the place where a spider has pierced a person’s flesh, and it will be cured. Also, the serpent and adder flee this stone and avoid the place where they know amethysts to be.
Amethyst: It's most celebrated occult virtue is a safeguard against intoxication. At the first signs of drunkeness, the amethyst should be placed on the stomach to draw the fumes in that direction, and away from the head. It also acts as a preventative; those that wear it may lose the desire to drink. It also has higher virtues of driving away evil thoughts, promoting chastity, attracting the favor of the great, repelling sorcery, banishing sadness, making the barren fruitful, although some say also that it can cause unhappy dreams.
