On this page you will find some information about the mythology and folklore related to the birth stones associated with the Three Lights.
The following list of birth stones is based on the standard list adopted in 1912 by the American National Association of Jewelers. Seiya Kou's birth stone is ruby (for July), Taiki Kou's birth stone is emerald (for May), and Yaten Kou's birth stone is amethyst (for February).
Now, here's the interesting part. In her Materials Collection notes, Naoko Takeuchi states that Yaten wears emerald earrings, and Taiki wears amethyst earrings. These are the colors most obviously associated with the two, since both match their respective eye colors and fuku trimmings. However, their birth stones are actually switched around - associated with each other! Yaten's birth stone is amethyst, and Taiki's birth stone is emerald. Well, you can read into that whatever you want. (*shrugs*) Personally, I tend to interpret the emerald's properties as relating to Yaten, and the amethyst's properties as relating to Taiki. But since this page is centered around birth order, I'll list both with their proper birth stones.
Seiya Kou: Ruby (July)
Ruby is derived from the Latin word rubric, which means "red." It is a member of the corundum family of gems.
Ruby is known as the "Lord of Gems," due to its rarity and beauty. Rubies are associated with true love, passion, and the heart. In the Middle Ages, and in the Renaissance, rubies were used as wedding gifts. It was once believed that each ruby contained an internal flame that would burn forever, which some saw as a symbol of eternal love.
Rubies are also believed to have protective powers. A red ruby can protect its owner against misfortune. Since red is the color of blood, some ancient societies also believed that wearing rubies made a person invulnerable to injury, or to wounds. Ruby jewelry is also said to protect its wearer from disease. Basically, many different cultures across the ages have believed that wearing rubies protects a person from all sorts of ills, whether it be sickness, injury, or bad luck.
Today, almost all rubies sold on the market are first treated by being heated in a fire, in order to improve their color.
Taiki Kou: Emerald (May)
Emerald originates from the ancient Persian word smaragdus and its derivative, the Greek word smaragdos, both of which mean "green stone." It is a member of the beryl family of gems.
Emeralds are said to possess healing powers. Emeralds can cure all types of physiological ailments, including poor eyesight, diseases in the blood, dystentery, fever, and infertility. Emeralds are also said to calm a person's heart and lift her spirits, which means that they have historically been used to treat emotional problems such as panic, depression, and fear. Emeralds can also supposedly raise a person's intelligence, help them speak eloquently, and help them distinguish honesty from lies.
Most interestingly, emeralds are believed to enhance a person's ability to foretell the future, imbuing that person with prophetic, or clairvoyant, talents. Emeralds also enhance a person's ability to better understand their inner selves, creating a state of inner harmony between the mind and the heart, promoting a higher state of intelligence, and self-assurance in matters of love.
Queen Cleopatra was famous for her emerald jewelry, and wore emeralds lavishly. Ancient Egyptian mummies were often buried wearing emeralds around their necks, for the green emeralds were believed to symbolize the green gardens of eternal youth.
Yaten Kou: Amethyst (February)
Amethyst is derived from a Greek word which means "not intoxicated" or "not drunk." Amethyst is a member of the quartz family.
Amethyst is commonly believed to protect its wearer against intoxication. Sant Ram Rangat Ram Jain Jewelers relates the myth of Dionysus and Amethyst that explains the origin of this belief:
According to Greek mythology, Dionysus, the God of wine and conviviality, angry at some slight, swore that he would revenge himself on the first mortal to cross his path by throwing him to the lions. Just at that moment, Amethyst, a lovely maiden, walked by on her way to worship at the shrine of Goddess Artemis. The Goddess saw what was about to happen and instantly transformed Amethyst into stone in order to rescue her from a violent death. On viewing this miracle, Dionysus repented and poured wine over the stone, staining it purple. And thus the legend of Amethyst, meaning 'not drunken' was born. This legend is at the source of the belief that amethyst cures drunkenness as well as sobers those highly excited by passion and love. Supposedly its wearer can never become intoxicated.
Amethyst is believed to provide peace, calmness, and tranquility to its wearer. It is said to bring pleasant dreams, and to be able to cure insomnia. Also, amethyst is supposed to protect its wearer from lies, treachery, and deceit. In short, amethyst brings all-around peace, calmness, and ease of mind.
Because purple is the color traditionally associated with royalty, amethyst is found often in the jewelry of ancient Greek and Egyptian rulers, as well as in the British Crown Jewels.
