Ruby, with its vibrant red hue, is often associated with the sun and is traditionally considered beneficial for those born under certain astrological signs. Here are some guidelines: Leo (July 23 - August 22): Ruby is particularly associated with Leo, a sign ruled by the sun. Leos are believed to benefit from the stone's qualities of enhancing strength, vitality, and leadership skills. Aries (March 21 - April 19): As a fire sign, Aries may also find rubies to be beneficial. The stone can enhance an Aries individual's natural courage, energy, and enthusiasm. Scorpio (October 23 - November 21): Though not a traditional match, some believe that Scorpios can benefit from rubies, as the stone can help to deepen their intensity and passion, attributes often associated with this sign. Sagittarius (November 22 - December 21): Sagittarians might also find rubies to be advantageous, as the stone can support their adventurous and optimistic nature. It's important to note that the use of gemstones in astrology is based on beliefs and traditions rather than scientific evidence. Individuals may choose to wear gemstones like rubies for their symbolic meanings, beauty, or personal significance rather than their astrological associations. If someone feels drawn to a ruby, regardless of their astrological sign, they may still find it a meaningful and beautiful choice.
