Mormon Dilemma 798 No Tattoos, One Pair of Earrings Only

Ensign, “Great Shall be the Peace of Your Children”, November 2000; “…the piercing of the body for multiple rings in the ears, in the nose, even in the tongue. Can they possibly think that is beautiful? It is a passing fancy, but its effects can be permanent. Some have gone to such extremes that the ring had to be removed by surgery. The First Presidency and the Quorum of the Twelve have declared that we discourage tattoos and also “the piercing of the body for other than medical purposes.” We do not, however, take any position “on the minimal piercing of the ears by women for one pair of earrings”—one pair.” – Gordon B. Hinckley

Proverbs 14:12; “There is a way which seemeth right unto a man, but the end thereof are the ways of death.”

Why is one pair of earrings okay but not two pairs?

Is this from the Lord or from the thinking of what the Church says is acceptable?
