Ruby, known as Manikya, is the radiant red gem of the Sun and one of the four great precious gemstones of classical tradition. Beyond its beauty, it carries deep astrological and even Ayurvedic significance. In this Astrokapoor guide, explore complete information about the Ruby gemstone — its composition, properties and who should wear it.
Composition and Physical Properties
Ruby is made of the mineral corundum, and its colour ranges from delicate pink to deep blood red, created by traces of chromium. It ranks 9.0 on the Mohs hardness scale, making it one of the hardest and most durable gemstones, second only to diamond. Natural rubies contain small inherent inclusions, and the deeper, richer red stones command the highest value. Cut quality and carat weight strongly influence price, which is why Ruby is honoured as the “King of Gems.” For its facts and lore, see our Ruby gemstone facts guide.
Astrological Properties of Ruby
In Vedic astrology, Ruby is the gemstone of the Sun and is said to emit warm, energising waves through its red cosmic rays. Because of this warming quality, it is traditionally associated with relief from cold-related ailments and with strengthening the bone system that supports the whole body. As one of the four classical precious gems, it amplifies the beneficial effects of a well-placed Sun, fostering power, wisdom, prosperity, good health and protection — the deeper science of which is explained in our Ruby stone astrology guide.
Ruby in Ayurveda
Ruby also holds a place in Ayurvedic tradition, where Ruby ash (Manikya bhasma) has historically been regarded as a rejuvenating, life-supporting preparation used to balance the body’s three vital elements (doshas). Classical texts describe its traditional use for conditions such as general weakness, pain and circulatory concerns, and for supporting healthy blood circulation. These are traditional Ayurvedic and astrological beliefs and should always be treated as complementary to, never a replacement for, professional medical care.
Solar Energy and Wellbeing
As the gem of the Sun, Ruby is closely tied to vitality, confidence and the life-force. Wearers traditionally report enhanced energy, self-assurance and a stronger sense of purpose, along with the Sun’s protective influence. Because the Sun governs the soul and the father in astrology, a suitable Ruby is believed to bring both inner strength and outer success, as detailed in Ruby, the gem of the Sun.
Recommended Wearers
Ruby is especially suitable for doctors, engineers, lawyers, artists, government servants, politicians, diplomats and stockbrokers — professions that reward confidence, authority and clear judgement. Creative individuals seeking fame, and anyone wishing to strengthen a weak but favourable Sun, may also benefit. As always, the Sun must be well placed in the chart, so an expert consultation is essential before wearing.
Choosing a Genuine Ruby
Because Ruby is precious and often imitated, buy only certified, natural stones from a reputable source, and have your horoscope assessed first. Astrokapoor provides certified rubies along with a proper Vedic gemstone recommendation, so you can be confident the stone is both genuine and suited to your chart.
