Basis of Selection of Gems
The main criteria for the choice of a gemstone is it's color. Vedic Astrology principles recommend selection of a gemstone on the basis of the following criteria:
Vedic Sun Sign
When birth data, like date, place and time of birth, are doubtful or unknown, a gemstone on the basis of the Sun Sign, selected from the month of birth, is recommended as per the following table:
|Taurus||Diamond, White Sapphire, Zirconium|
|Libra||Blue Sapphire, Amethyst, Lapis Lazuli|
|Scorpio||Hessonite, Brown Tourmaline|
|Sagittarius||Yellow Sapphire, Citrine|
Date of Birth (Janma Tithi)
Each day is ruled by one of the eight planets from Sun to Rahu. A gemstone is recommended based on the ruler ship of the day of birth. This method is not a very popular basis for selection of gemstones.
Weekday of Birth (Janma Vara)
Each day of the week is named after one of the seven planets ( from Sun to Saturn) and is ruled by that planet. A gemstone is recommended based on the ruler ship of the day of the week. Once again, this method is no longer a very popular basis for selection of gemstones.
Ascendant (Janma Lagna)
The Lord of the Ascendant (Lagnesh) is the controller of life forces (jeeva). Based upon the determination of the Ascendant, a gemstone is recommended to be worn as a ring on the ring finger.
Planetary Periods (Dasa)
The rulership of the current planetary period (Dasa) or sub-period (Antardasa) is very often used for selection of a gemstone to bring relief from malefic effects of the ruler or to enhance its benefic effects.

Precious and Semi-Precious Stones
Actually the gem stones found at present are innumerable but according to the specialist of Indian Gemmology there are 84 gem stones. Amongst them nine – Ruby, Pearl, Emerald, Yellow or White Sapphire (Pukhraj), Diamond, Blue Sapphire, Gomedha and Cat’s Eye occupy the prestigious category of Navratnas. Five of them viz. Ruby, Pearl, Diamond, Emerald and Blue Sapphire have been given the distinction of being termed as Maha Ratnas (superior most class of gems). These are also precious stones and the others are classed as semi precious stones. But there are several semi precious stones which by their brilliance and luster do not look inferior to some of the above mentioned Nav Ratnas(nine gems). In hardness, durability, scarcity, luster and transparency they do not lag behind the Nav Ratnas like Emeralds, Gomedha, Cat’s Eyes and Sapphire.These stones are very importent for us.
