Ruby, ruled by the Sun, is a powerful gemstone that doesn’t suit everyone. Those with a weak or afflicted Sun in their birth chart, including placements in challenging houses like the 6th, 8th, or 12th, should avoid ruby, as it can amplify stress and arrogance. Additionally, water signs (Cancer, Scorpio, Pisces), individuals with aggressive personalities, or those prone to anxiety might find ruby too intense, leading to irritability or heightened emotions. People with heart issues or high blood pressure should also be cautious, as ruby’s energy can overstimulate. Always consult an astrologer to ensure ruby’s compatibility with your nature. Read Blog
