Where Gemstones are found

Some gem minerals, such as quartz and garnet are found world wide. Other, like dimonds and emeralds are rarer, due to the more unusual geological conditions necessary for their formation. The physical properties of gemstones, their hardness, theri specific gravity or density, and the way they break or cleave, depend on cemical bonding and the atomic structure within the stone.
Many kind of gems occur in more than one environment.

Colour is the most obvious visual feature of a gem, it depends largely on the way it absorbs light. Each gem in fact has a unique colour "fingerprint".

Emerald, the color of spring, derives it's beautiful green colour from the presence of chromium and vanadium. Emeralds are rarely flawless, so stones are often oiled to fill and disquise cracks, hide flaws and enhance colour.
Occurrence: Found in granites, pegmatites and schists, as well as alluvial deposits. The finest Emeralds are from Colombia. Other sources are Austria, India, Australia, Brazil, South Africa, Egypt, USA, Norway, Pakistan and Zimbabwe.
Most Emerald used in historical jewellery, would have been from Cleopatra's mines in Egypt, which now yield only poor quality Emeralds. The Egyptians were known to engrave Emeralds with the symbol of foliage to represent eternal youth and bury the jewelry with their dead.
The ancient Romans associated this gemstone with fertility and rebirth, and dedicted it to venus the goddess of love and beauty.
Some people beloeve that wearing an Emerald brings wisdom, growth and patience.

Before I am starting with my once a month education about gemstone, I would like to explain what is gemstone also called a precious or semi-precious, this stone is a piece of attractive mineral which when cut and polished is used to make jewelry or other adornments. how ever certain rocks (such as Lapis-lazuli) and organic materials (such as amber) are not minerals, but are still used for jewelry and are therefore other considered to be gemstone as well.
Most gemstone are hard but some soft minerals.

Birthstone: are gemstone that are associated with each month. they my be precious stone (like diamonds) or semi precious stone (like Amethyst) they are considered lucky for their particular months and for those who believe in such things their healing power are heightened during their months.
Birthstone started back in the 15th century and more modern birthstone were officially adopted in 1912 by the national association of jewelers. It was believed to give it it's power. With time birthstone began to be associated with their respective months. People wear birthstone jewelry to represent their birthday as well as their personality. there are few way to look at birthstone: Zodiac Birthstone, traditional and modern.
