Since the first century particular gemstones have been associated with the signs of the zodiac and have been incorporated into gold and silver birthstone jewelry. Originally birthstone schemes were based on the color of the stones and the origins are thought to be associated with the Breastplate of Aaron which held gemstones associated with the 12 tribes of Israel. Each gemstone had the name of the tribe enscribed on it and they were attached to the breastplate in four rows of three. Although the names of the gems used are known, the exact translation is debatable so the particular gems that were used is not known and has led to different gems being associated with the different months of the year.

The Modern Birthstone Scheme
In later times birthstones became associated with the months of the year rather than the signs of the zodiac and there has been some differences in which gemstone is assigned to which month. The most widely used list today is one which was proposed by the Association of Jewelers in America in 1912, and includes some alternatives to the more expensive gemstones. There has been one addition since then. Tanzanite was added as a birthstone for December in 2002 by the American Gem Association although this is not recognized by everyone.
There are other schemes which associate particular gemstones with the birth month including mystical birthstones and Ayurvedic birthstones. The mystical birthstones scheme dates back to over 1000 years ago and is from Tibet and the Ayurvedic birthstones scheme comes from ancient Indian philosophy and dates back to around 1500 BC. Most people however use the modern scheme proposed by the Association of Jewelers.

For four thousand years Peridot has been mined as a gemstone and is even mentioned in the Bible under the Hebrew name of pitdah. Peridot is the national gem of Egypt and was used by the Egyptians as early as 1500 B.C. It was called the “gem of the sun” because early miners held that it shone with a light that made the crystal easy to find. This gem is becoming wildly popular because of the historical legend denoting it as Cleopatra’s favorite gemstone.


In the past the major source of aquamarine was Madagascar which produced gems with a darker blue color. Today most aquamarine gems come from Brazil and is bluish green in color. Aquamarine is also produced in Tanzania, Nigeria, Zambia, Zimbabwe, Kenya, Sri Lanka, Russia and Afghanistan. It is also found in the US in Colorado, and Wyoming.
The name turquoise is thought to come from the French word meaning Turkey as it was mistakenly believed that the gemstones originated in that country as they were traded in the bazaars to European merchants. In fact they probably came from the Sinai Peninsula or from the Alimersai Mountains which are now in Iran. It may also have arisen from the French word for dark blue stone, pierre turquin. It is often found in deposits of copper usually in very dry, arid conditions.
