The red precious stone known as a symbol of love is the ruby. Rubies are valued for their vibrant red color, which can range from pinkish-red to blood-red. Historically, rubies have been associated with passion, romance, and power. They are often used in jewelry, particularly in engagement rings, to symbolize deep affection and commitment. Due to their rarity and beauty, high-quality rubies can be quite expensive, often more so than diamonds of comparable size. Rubies are also believed to bring good fortune and protection to their wearers, further enhancing their appeal in both personal and cultural contexts.
