Diamond’s name is derived from the ancient Greek word adamas, which means invincible or untamable.  For that reason, diamonds are thought to dispel fear, and to promote emotional, mental, and physical fortitude.  In antiquity, diamonds were considered antidotes for poison, including snakebites. They also were believed to offer protection from the plague.  Although about half of the world’s production comes from Africa, diamonds are also minded in Canada, Russia, Brazil, and Australia.

To chart their position at sea, the Vikings needed to be able to locate the sun even on overcast days, and iolite enabled them to do so.  Gem quality iolite is cut to maximize its blue or violet blue color. It is mined in Sri Lanka, India, Brazil, Mozambique, and Madagascar. New Agers use iolite for detoxification and emotional cleansing.

Peridot gets its name from the Arabic word faridat, which means, “gem.”  Peridot is always green; however, the depth of the green varies from yellow-green, to olive, to brownish green.  Peridots were cherished in antiquity by the Egyptians and Romans who wore them as amulets. Recent new finds in Pakistan and Afghanistan have created a resurgence of interest in the stone.  Peridot is also mined in Myanmar and Arizona. Practitioners of New Age metaphysics use it to regenerate the spirit and the heart. Peridot is the birthstone for August.

They were also believed to facilitate the ability to give and receive unconditional love.  Rubies are mined in Myanmar, Sri Lanka, Vietnam, Madagascar, and Africa. Ruby is the birthstone for July.
