The ancient civilizations were convinced that there were just seven planets : Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn. It was also strongly believed that the astrological positioning of these planets at the moment of birth affected an individual's destiny.

The seven planets were believed to influence their designated day of the week:

• First day was influenced by Sun or Surya
• Second day by Moon or Chandrama
• Third day by Mars or Mangal
• Fourth day by Mercury or Buddh
• Fifth day by Jupiter or Brahaspati
• Sixth day by Venus or Shukra
• Seventh day by Saturn or Shani

In the Middle Ages, seven metals had been identified by the alchemist. The metals were then matched with planets :

• Gold (Sun) : Gold expresses the splendour and radiance of Sun. It is the only metal that never tarnishes and resists the fiercest of fires. Gold is associated with riches, rule and truth. Sun is the centre of our solar system and gold is the core of every aspect of life be it economy, rule or comfort. Gold is used for wisdom, for fighting depression depression, comforting and strengthening the heart, wealth and healing. Gold or golden colour is used in rituals involving Sun God. Like sunlight, gold is also diffused through Earth's crust. The Sun's position in the horoscope is said to express one's true destiny. Thus, the uniqueness of gold and Sun make them a matching pair.

• Silver (Moon) : Silver is ruled by the Moon also called Luna by alchemists. Silver is used for protection against magic. The symbolic meaning of the Moon is reaction and reflection. The Moon acts as a mirror reflecting the light from the Sun and a mirror is just glass with a thin layer of Silver.
