The Sun God, the ruler of the Leo zodiac sign, is the eleventh house in the horoscope of a Libra ascendant and is considered a malefic house. When the Sun is placed in the sign of Libra, it is deemed debilitated and typically produces unfavorable results. Under no circumstances should the person of this ascendant wear a Sun Gem Ruby. Unfortunately, the Sun does not bring any positive results for the natives of a Libra ascendant.
