"The Diamond, symbol of innocence, purity, and strength. Diamonds gives courage and strength, protection from pestilence and helps the cause of true love. But take heed of this warning: Diamonds gained by treachery or violence, or desired out of envy or greed, are ill omens, and bring bad fortune. Great evil comes upon those who gain them without honor." —The Belt of Deltora, Deltora Quest
Purity and strength. Yes I can see that. The crystal blade is very pure while the arrow/spear is good symbol of strength and innocence as well if you look into the story of the Goddess Diana.
