I usually try to maintain a hard head and not get involved in astrology, and other non scientific stuff - but I keep on finding that there are coincidences - my birth sign Aries is associated with the purple form of amethyst, it is made up of layers of alternating left and right turned molecules - I am quite ambidextrous.

What is the only piece of jewelry I have with 'real' stones in? A ring set with pale but definitely purple amethysts. It is quite pretty with a base of gold and then a narrower strip of silver through which the amethysts can be seen. I knew nothing about its chemical make up or crystalline properties when I bought it.

If you have a choice, I suggest that you select a stone, crystal or mineral which resonates with you - or has some association for you - even if it just on 'Ooo that's nice' reaction - you might find out that there are connections.
