ARIES (March 21-April 19): When Spanish conquistador Francisco Pizarro laid waste to Peru in 1532, his soldiers found green stones on the land. Were they emeralds? A priest who was traveling with them gave them bad advice. He said that the way to determine whether they were merely colored glass or else precious gems was to test their hardness by pounding them with hammers. In this manner, many actual emeralds were shattered into fragments. Learn from this mistake, Aries. Make sure you recognize treasures for what they are. And don't force them to submit to unwise tests that misconstrue their true nature.
