Precious stones have been used as fashion jewelry for ages. The attraction towards colorful stones starts at a very young age, and one is fascinated by a particular color, depending upon ones state of consciousness. Stones are natural storehouses of colors. They are the catalysts for the rays of the SUN and as you know Sun is the father of our solar system and without Sun we will not survive.  
Analyzing the spectrum of seven colors from a holistic approach, each color represents a particular area of existence. Red is the color for fire or heat, and it has the potential to give comfort as well as to burn, Blue is a cold color, and variates between calmness and freezing, Orange and green represent healing, yellow is the color of expansion and so on, whereas white is a neutral color and black is infinite and a absorber of the weak colors, black also represents absence of light.

Hi,
I am born in the month of FEB so i bght AMETHYST but there were many problems after that what shoild i do??

Gems if not worn under correct guidence act as a curse rather than cure..many astrologers in India prescribe Gems on the basis of generalizations..The right gem to be worn needs in depth personalized study of the horoscope.Any one who wears a Gem of a malefic planet or a flawed gem even out of ignorance will face problems.

I think that many people would contend with that "flawed gem" thing.  All stones are manifestations of God and as such are to be cherished.

Isn't it lucky for us that gems do not spurn flawed people?

First off green is the heart chakra, red is the root chakra. Red = passion... green = tranquil healing

I think if the stone doesn't like how it's being used it will back fire. Or if the stone absorbs bad energy and is not cleansed it will amplify what energy it absorbed. But if it's cleansed regularly then it can act as powerful protection from bad energy. Also many stone don't like a lot of people for obvious reason(as least it's obvious for the stone) and if they don't like the position they're in they will find a way out. I've had stones leave me. It's crazy seeing in retrospect how a whole situation arose just so a stone could move to an environment in which it could function better.

If the stones are utilized properly, they are very happy to put their healing energies to use.
