TL;DR>>In the Eastern Astrology system the Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn will rule the houses of your astrology chart. These houses are similar to Western Astrology but not quite. Note that Uranus, Neptune, and Pluto are not considered in Eastern Astrology. Eastern Astrology planets are beneficial or troublesome depending on your Ascendant sign and what houses they rule.

Certain gemstones are ruled by the planets in this system and can be helpful in mitigating troublesome planets. Not all gemstones have a planet ruler. Eastern Astrology also has planetary periods which have no equivalent in Western Astrology. When a gemstone is listed as sometimes beneficial, it is because during that particular planetary period that gemstone will be beneficial. For example, if said person is in a Sun planetary period, a ruby or garnet may be beneficial, but an astrologer must be consulted to determine what planetary period the person is in and if that particular planet is not afflicted by other malefic planets.
